[@stamatisvragas7720]

34:35 is actually a good time. The average non runners time is around 40. Also take into account that vo2max is based on weight too so hou must have around 53-55 vo2max ehich is a lot

Your tip on removing the air from your water bladder to avoid the sloshing noise is a life saver! I never realized how annoying the sound was until I forgot my headphones at home and went for a run without them. Thanks for the awesome advice!

[@NateMegOfficial]

Oddly, I didn’t mind the slosh when I first tried a camelback. The rhythm was actually cathartic while I was running (also have a music background so anything that sounds like a metronome is oddly relaxing).

[@FocusingOnChrist]

if you forget to empty the air before you go, just bend over and take a drink. keep sucking and most of the air will exit

[@Burps___]

I like the tip about removing air from the bladder, thank you. Another tip that, literally, 95% of runners struggle with is bladder storage. To avoid mold, they brush them and hang them and put a fan on them and prop them open, etc etc. All they need to do is refill them with water again and put them in the refrigerator. Boom, no mold. Want fresh water for your run, dump out the “storage” water and refill with fresh water the night before the workout. Simple and works like a charm! 💦 Love water!

[@MarkLewisfitness]

Nice tip!

[@iamrobot396]

Nice fucking tip! alternatively what do you suggest to store the bladder on a hike. i thought dumping a few chlorine tablets on it and then swap for fresh water after

[@csn583]

@@iamrobot396 Why are you storing it on a hike? Are you thru-hiking for months with a spare or something? Otherwise you're just not carrying it empty long enough for this to be a concern. You're constantly moving new clean water through it. If pulling water from natural sources, personally I filter and also use Aquamira bleach tablets. Whatever bottle/bladder you're bleaching in (for 30-60min) will be handily sterilized in the process. 🤷‍♂️

[@csn583]

Also, if you have an already-nasty old bladder (or whatever, glass and plastic), get yourself some PBW. Designed for cleaning brewing equipment without scrubbing. Just shake a bit in and fill with water and in a few hours every unreachable corner will get that scrubbing-bubble magic, then rinse. I like the fridge tip too.

[@kombava7275]

I store mine in the freezer between hikes. I usually run without water because i don't have a small backpack yet, but i'll buy one soon as i'm starting to run more 15+ km runs.

[@sanan22]

it depends on intensity and temperature. I've done 21k and a comfortable pace at -20C without water, because my water was frozen the entire run.

[@sachakopa7964]

Yeah, I did the same about an hour north of Toronto, Canada two winters ago. It was evening, -20, ran 21km, 1h 45 mins. I wasn’t cold though. Body warms itself up just fine after 3-4 mins. The trick for me is NOT to try and keep the core to warm by bundling up. Long sleeve, lightweight Merino base layer, windbreaker, neck gaiter, light running toque, light weight merino long underwear, windbreaker running pants and gloves to start. Gloves, toque and gaiter come off after about 5 mins and unzip the windbreak to the belly. This way your core activates and you pump blood to your extremities (hands, head, ears). The second I try too zip up the jacket is the second my hands, ears and head start getting to cold. Only problem was that when I was finished the run, I forgot exactly where I’d parked my car. Let me tell you, while running, the body took care of keeping itself warm but once I’d stopped for 5mins plus I was really really cold. That and once I found my car, I discovered the battery was dead. So I used my phone with my shivering hands to call CAA for a boost and froze my ass off for the next half hour till the tow truck showed.

I run with a 250ml soft flask in my pocket and sometimes use it. Brilliant. Great video.

[@LasseBuck]

So true! Runners adapt differently to reducing hydration during runs, but most runners will find that there is lots of room for change. I don't hydrate during a training run if it is less than 2 hours long and I find that it doesn't affect my performance much.

[@MixFixKitten]

Not you pointing out the obvious about running about 'running with a water bottle in hand is like running with a weight in your hand'. Really glad I watched this video today. I was about to buy one of those bottles tomorrow. Great insight! Thank you.

[@Chris-mn7yy]

I always carry it, because I like to have some with me. Maybe don’t need it but my ultra vest makes it easy.

[@AndrewSmith-cd5zf]

Lovely advice, just don’t try long running in Australia with this strategy. A small hand held 250 ml bottle will work well if water points are separated by 10 km or more. Also in competition a small water bottle will allow you avoid the overcrowded water station’s- you can run past cleanly on the other side of the road and use the uncrowned tables at the 25 or 35 km mark.

[@kennymacm3031]

I’m terrible for not drinking enough through the day and I’ve just spent ages looking at running packs because I’m doing an ultra in June, watched this and realised when I came 13th out of 100 in a 10k in Belize….in the heat/humidity that I got a glug before and at the end. I’m still here thirty years later!!

[@DriveandThrive]

I love my running vest. I keep a headband to wipe away sweat, keep a few gels in the back, and of course water. But I’m slow asf and so my runs are often 2-3hours long. For me the water and gels are life savers (I also don’t care much about my time performance)

[@stephengoodfield2530]

😂😂😂 love it. I’ve actually gone the opposite way. Started taking no water up to half marathon distance but am now taking water on my long runs. I find it just makes my overall running experience better as I’m not gagging for a drink those last few km.

[@DriveandThrive]

Anything 10k or more and I’m bringing water. I’m also in Thailand so it’s hot and I sweat a lot. Actually I enjoy 0 calorie gatorades for electrolytes and over 10k I bring gels because I’m slow

[@alexpotanos6752]

I’ve been taking 500 ml with me on short 4-5 mile runs, and seen a lot of improved performance. Maybe that means I’m not hydrating properly during the day but… 🤷🏻‍♂️ life happens

[@JMijares]

Thanks for the tips. My favorite race vest is by Salomon. I like keeping the water in front and usually switch between 750ml and 500ml bottles, depending on how long and brutal the race is.

[@1960Martin]

Great info. Mark, thanks. I did a 10K a couple of years ago, it was about 29degC...in England! And the route was in full sun, no wind, black tarmac. As an experienced runner, I knew I probably wouldn't need to hydrate during the race, but did so beforehand and certainly needed water afterwards. There were a number of runners in serious difficulty though, they clearly didn't hydrate adequately beforehand and were staggering all over the place and having to be helped towards the end.

[@edwin5419]

Man I'd kill for a 29C day. Haven't had one that cold in months.

[@georgelane6350]

Great advice, i did a road/trail marathon today. Got through

[@royfr8136]

In Mexico it's a must. Surely it just depends on the temperature? Also the distance. Hydration through the week to prepare is a must for sure. Carrying anything in your hand, even a t-shirt, over time and distance creates problems - with rhythm and muscle aches. When going on training runs here in Mexico I hide my bottles in the bushes at certain points in the run. Now, in events (where water is provided) I still only carry my water belt in order to take on gels (which need to be taken with water). For beginners its good to know what you really need. I too did events where music was not allowed - so I got used to no music - but I think music is a helpful tool for motivation while training.

[@EnterTheFenix]

I rock the Salomon 12 vest for everything over 10k .. i'll usually fill the bottles up max with ice water and just use it as a sort of weight vest for shorter runs.. might take a sip if the mouth gets dry, but ive only ever used it for hydration on 18-25km + runs .. mainly i stick with it because i like it for marathons.

[@elvagar]

For me it was the opposite . I never carried water and have never used earphones. On my first 10k trail race I have had my first mid run sip of water and realized how much better the running is when you're not completely dried up :D I think it is more of a mental thing that I was able to push myself harder after a few sips of water. Now I take water on every run that is 10k or longer. My small flask is 250ml, but depending on weather and length I can take more. Also I have learned to appreciate earphones, when I was doing a long slow runs on a track.

[@supermitendo9654]

Longer than 10k, sure, but 10k run is only 1 hour even for beginners and the common recommendation is to drink about 500ml or one bottle of water per hour. By the time you need to drink your water, the run is over 😂

Never understood why people wear earphones while running, but then again when I started running I would only run after nightfall as I thought my pace was just embarassing and I didn't want to be seen, so what do I know :P )

[@pistonhung]

Here in Vietnam with avg 30°C, quite humid, I often started morning with fasted 20k-25k easy run. Sometimes fasted 40k-45k on weekends, of course slow and easy pace. Not trying to convince anyone to do it but I think we can do little by little as long as we feel comfortable.

[@johnrobinson4445]

Running in Northern Arizona (elevation about 6,000 feet, on the Hopi lands), I routinely rain 10+ miles with no water. If you drink water all day it is no problem. I was running in the early evening in the summer. However, when I ran a 20 miler, I believe I did take a small bottle.

[@Go_Irish]

This is great advice. I've gotten into longer distance runs over the last 6 months. I don't carry water unless my distances are 10 or more miles. I use a Naked brand belt (tried a few and this is the best for my setup). I use collapsible flasks to hold the water and carry the 8.5 oz size for 10 miles. The 8.5 oz and 5 oz sizes for 15 miles and so on. Your body should definitely have the hydration needed for anything under 10 miles as long as you are hydrated to begin with and aren't running at elite speeds.

[@Gumpmachine1]

Honestly I don’t take water until I run further than 25km. Marathon is the only distance I’ve been caught out on for not hydrating enough

[@hocsll]

I run in Singapore, the average evening temperature is 30C, 70-80% humidity. Not having *iced* water, even at night, for runs >6km can be dangerous. Heat exhaustion can be potentially fatal. I also pour water on my skin as a coolant. With climate change, temperate regions may also get dangerously hot. Something to think about.

[@megachristy9838]

I second that. I live in Abu Dhabi where summer temps exceed 48 degrees and stay at 37-40 in the night. Lack of water can literally kill you. That said, I see where you're coming from

[@sergiofartlips]

In the state of Tennessee or the south eastern region of the US, the average summer humidity during the day is up close to 92% with a high in the upper 90'sF Im.

[@thecasualhobbyist9710]

Hey! I’m from SG too I’m planning to do my first 10k and was thinking of getting a running vest. The route I’m going is from Punggol to Tampines and there’s very little stops that offer water etc. do you think it’d be a good idea to get a running vest?

[@toi3213]

Most of us not elites.

[@Prod-23]

You gained a sub. I've just started running again and the only reason I wanna carry just a bit of water is that my mouth gets so dry, not really for hydration. As you state, you should ensure you're hydrated before the run.

[@vintage910]

Look into breathing entirely out of your nose. Can go miles and your mouth will still be moist. Takes some time getting used to though!

[@emanuellerizzogomespereira4200]

I have been running (5k to 15k) not carrying any water with me over the last 10 years but I had many dehydration episodes (dizziness, heart racing…) which made me very cautious and scared of facing it again. I decided to run with a vest with 500ml water capacity… it calms me down!

[@simonchis9333]

Def with you on the salomon adv 12 vest. I just always wear it now. Doesn't bother me and I have everything I need for a run what ever the length so I can decide how far to go as I run.

That's exactly why I carry a vest even when it's just a shorter distance.

[@robertjones7023]

Thanks Mark, I just ran my first solo 10k in 85 degrees (F.) and 80% humidity with nothing but a tee shirt, shorts, and running shoes. I remember listening to your advice to hydrate prior to the run and wala! I did not die. I stopped 4 times to catch my breath and reset my heart rate. Other than that it was doable. I am going to keep pressing on with miles, so I'm looking for a small water source.

[@lorim2000]

Awesome advice. I’m a backcountry hiker who does a little trail running and this all rings true. I’ve learned how to hydrate properly ahead of time and carry less during activity. It’s amazing. I hate heavy packs period. I have friends who continue to struggle in this area but I finally feel like I have this dialed in for myself.

[@alfromtx245]

Good stuff. I've dehydrated a handful of time, even when I've carried water. The problem was that I had done something in the heat (yard work, running, etc.) the day before and hadn't properly hydrated. Living in Texas, I do tend to carry some water on summer runs that are longer than about 45 minutes. But maybe I could try and extend this to an hour or so.

[@cpruns4501]

This is an awesome video and I love your style. You are 100% correct that up to 10K in normal conditions you don't require extra water if hydrated properly. However, I do find I can end up with a sore throat if I let it dry right out for too long (heavy breathing in and out and really dry). SO...what I found works well is to get a flexible 250ML bottle and fill it 3/4 of the way and keep it in your front pocket. You hardly know it's there but it gives you just a sip of water every 2-3K just to keep your throat damp.

[@ianjones9322]

Yeah I run.13 k at least twice a week and my spittle is ruining my fluency, u have just purchased a camel pack so I can gargle and resolve this issue, I doubt I will drink as I fear stitch but I definitely need lubrication

[@Gran_Torino]

I did my PR half marathon 2 years ago (april 9 2020) in 1:23:53 at 3:59 min/km without any water. Never run as fast before or since (I gained weight since then, trying to get back to that form and better now). I never drink water for outdoor runs below 20 km. Indoor at a treadmill I sweat like a pig so I make sure I'm well hydrated before and also drink 0,5 liter during the run. Any more than that and I usually need to go to the bathroom - and not the quick one.

Totally agree - mistake in hydration are very common. But I'd say, handhelds are VERY underrated, and worth a second look in ultras once you get to a certain level - not for all context but certainly great for faster paced 100k.

[@kristofbe1]

When I clicked this vid, I was ready to start disagreeing with you... but I don't. As a heavy sweater living in a hot place, running without water is rarely an option for me. For runs of up to an hour, I usually take a flexi bottle that I stuff in my short pocket. Not ideal, but it works. For longer runs I use Adv Skin 8 vest by Salomon, which is really great. It holds 2l of water, but I only fill it completely for 3h+ runs. On top of that it has room for smaller bottles in the front that I use for electrolyte drinks. Thans for the tip on the belt, though. I've been looking for a good one. Great vid!

[@jelly-baby]

Useful, as a regular 5-6 km and infrequent 8-10 km runner I have never taken water, and very often just get up, clean my teeth, put on running gear and go. I'm surprised how many runners I see carrying bottles. As long as you are well hydrated the day before you should be good to go.

[@carsonecombs]

As a beginner I never even realized how important hydration was. Water was not a concern. Now I realize that as long as I drink about 13 cups (8oz) or 3L a day I can go for 90-120 minutes (at an easy pace) without any “need” for water.

A real danger with dehydration is also blood clots, which can further lead to strokes and heart attacks. As lack of water in your blood thickens the blood, and thus increases risk for severe adverse effects. But beyond that it's good for a vast amount of reasons. And it tastes fantastic! :)

As has already been said, it depends on intensity and temperature. I have done many easy long runs of 3 hours with zero water and no gels. I have also ran marathons with zero water and a couple of gels. Other runs of higher intensity or higher temperatures i take on water and/or gels.

Just got back from the alps, climbing mountains, some over 3,000ft in elevation, and then I ran the trail down. Most runs were in 30c+. I did one without water bottle in hand and tried on another, but it became essential and a huge help. I wasn’t swigging at all. Just a little bit to wet the mouth. It helped massively in that heat. If you feel the need for liquids, don’t deprive yourself. But guzzling it down won’t do you any favours.

[@NinjaElephant]

I‘ve been running for 16 years now and with 95 kg and a heavy sweater having white shores on my sleeves every run I always assumed I need massive amounts of water. But in fact I can dehydrate a lot more without a drop in performance than what I thought possible. I now almost never take water with me. If the run is over two hours - rare - I might consider it. If it is a trail run with uncertainty and no gas stations, I take water or sugary tea. Bring a Credit Card and an FFP2 mask for gas station stops. I almost don’t drink during half marathons with fair times (1:30 ish). Longer races like marathons should be hydrated especially when hot, but 500 ml per hour or less is probably enough (for me!!!). The only time I really DNF dehydrated was during a L’Étape du Tour cycling Race with 4,600 m of climbing on a 35 degree Celsius day with no wind after 10 hours. I would have drank (drank?!) more but repetitive puking wouldn’t allow it. 🤷🏻‍♂️

[@orangew3988]

I find this video so funny, because as a 'runner' over the years, I have always been a beginner, never ran more than 6k and it has never occurred to me to run holding water before! Maybe because I'm more a rugby player who attends parkrun haphazardly for fitness, but I don't play rugby carrying water, so I've never tried running carrying it either! I drink before I start running, and back in the day when i ran more, I would leave my water bottle and jacket somewhere and loop back round for a drink on the way sometimes. If anything, the issue with the idea of going out the house for a run I find is that I need a jacket for warming up, but then I totally don't need it at all when actually running.

Spot on . . . I can do about 10 miles without water depending on humidity but I carry 1/2L anyway. I just sip it as needed. If I go 20 miles I drink a lot between laps and carry two half liters for the second leg. Organized races provide water but training hikes you bring your own which is why I do 10 miles twice rather than 20 miles, so I can be at my car in the middle of my session.

High altitude and dry, you're going to lose a lot more through breathing thank you realize. If it's hot and humid, you get the point. But absolutely ⬆️.

kipchoge is definitely hydrating during a marathon, all elites do and is essential part of training for that distance

[@Demondoink1]

i'm the opposite end of the spectrum. i would never carry water and attempted to run a marathon by myself one evening on 500ml of Lucozade lol. having just completed my first marathon at the weekend, i now realise how much i was holding myself back by not drinking enough, or eating enough throughout the run. i didn't need to stop once and beat my target time by almost 20 mins by drinking a small amount at each drink station and eating a couple of bars whilst running. for me it was better to under do the hydration cos it meant on race day it felt so much easier when i was adequately hydrated (though perhaps this isn't the most healthy advice haha).

[@hendriks_kevin]

I just started running a couple months again, started running with a belt with to small bottles (200ml), from the second day, because I got thirsty (I know hydrate more, always an issue). But I always bring it and pack it on small runs like I am going to do a long run. Just to train with having equipment. I have been doing walking marches for almost 20 years now (4 days x50k or 80k on one day) and also pack for a big march, that way my body is used to the equipment and I can test stuff out to have improvements.

[@WoolyJumper5]

thanks Mark, super useful.. amazing how i'd never thought of all this but have been jogging for years ..

[@kft4764]

I whole heartedly agree lots of beginners overestimate their need for water (and food)

[@AZHighlandHomestead]

I’m so happy I don’t have to throw away my camelbak. The RoboCop Ms. Doubtfire look whilst on the trail is what my dreams are made of! ❤

[@willneverforgets3341]

it depends on the weather conditions too, In the UK you can pretty much do from Sept to May without water in any run up to 10-12k... Here down in Spain it is the opposite, you have to carry water even if it is a small 250ml flask for short runs.

[@typrzemek]

There is a video on you tube about a guy who serves water to Kipchoge has the nickname "Bottle Klaus". This means he drinks water during a marathon

[@playerzero2236]

I would ignore the noise and bring water especially if you do high intensity training in high temperatures.

[@legacydentco]

You’re right man. I ran 31 miles yesterday, and it’s too tempting for me to wanna take sips along the way, so at mile 15 I threw my guts up. Realize my body wasn’t even processing all that water I was drinking. I’m not taking any next time. And just stopping at a convenience store if necessary. 🤜🤛

[@jamesarendse9739]

Watching this before breakfast is not a good idea. Great video, love the presentation style.

[@flyingfrog7847]

Probably also depends on how fast one sweats. I'm a heavy sweater, and if I run over 40min without drinking, i'll fehydrate so bad my head hurts the next day.

[@binarysun_]

This is interesting insight and kinda mimics my SO. She HAS to have a water bottle with her even on shorter sessions. That's especially interesting since I went the other way around. I never took any water with me because I learned through a lot of biking during my "active" time as a cyclist that I don't need any water for a one hour ride. It was fine in the beginning when my usual run was a 3-5k run. Then when I got better and had I my first slow 10k-ish run which took me like 1h30 it became horrible because it was kinda warm and I had no water but started to notice a dry mouth around the 5th k and it really started to get uncomfortable at around the 7th k. I have two bottles now. a small 300ml silicone bottle for the distances/times where I noticed that I at least need to rinse out my mouth from time to time (like anything up to an hour and not too hot) and a 600ml bottle for runs where I know I need something to drink (my weekly long runs through secluded forrests). I now face a similar thing with running nutrition. Because I thought it MUST have caffeine in it and it took me a while to recognize that the uncomfortable surge in fatigue that I have 45 minutes after my "dose" is not me getting weak all of a sudden but the caffeine wearing off which feels kinda brutal and lasts for like 20 Minutes. What helps me most for some reason is just taking a gummy worm with me and eating that in little pieces😅and maybe adding some plain unflavored electrolytes to my water on really hot days.

[@plowestv]

Mark, relatively new to your films and they make me laugh. This one made me laugh BUT also, I agree with EVERYTHING you say here. I carry water when I need it. Leeds marathon last weekend, needed quite a bit! Love my vest and its 2 bottles. Thirsty horses for courses :-)

[@noreply-mp]

Thanks for the sage advice bruvva. Going out for my first jog tonight without a water bottle

[@GodzillaGoesGaga]

About 12k is my limit where I’ll NEED water. On longer runs I take my running vest so I can constantly hydrate slowly. You really have to be ahead of the game for longer distances.

[@claireonlinex]

Your delivery was so funny, great advice

[@girlsgonefishing3758]

I'm only a beginner but I don't carry water with me as I worried about having the extra weight on me and just drink water as I'm getting my kit on to go for a run. I was a bit worry that I was not doing my body good so I'm glad you've confirmed what I was doing is fine. Thanks a lot for this video

[@mikerobinson9836]

When I hydrate properly I have run for an hour without drinking. I feel I struggle more when I do drink during a run now. Although over an hour I would need water and probably some sort of energy tablet/gel. Less during more before has really improved my times!!!

[@edwin5419]

We have weeks over 40C. This Summer's average is 33C. I don't usually carry water for anything less than 10km, but only because I know where all the bubblers are. I'm similar size to you - 104kg, 6'4. In Winter I don't take water for less than a half marathon. I can't stand camelbacks or vests, so I carry a 600mL water bottle.

[@Ajumi-]

I never took water with me so far, but i might prepare a „secret water station“ on my first (private) marathon. (with the snaks which i already tried which work for me with running) Planed is to take a real break at the half of the distance, i don’t want to run through the whole distance.

[@GlidingChiller]

I bring water on my long runs and sometimes even gels, not because I urgently need them but because I always want to train drinking and eating on the run, something that a lot of people seem to have trouble with in the beginning.

[@Andy-Aims]

It's kind of useful for beginners, lol. You wouldn't want them thinking they could run in the desert with no water.

[@joeproctor2216]

This is the best video I've seen so far. I feel I'm a decent runner, but this long distance stuff is kind of new to me and this info here was perfect. Got a new die hard follower, sir. Thank you so much!!!

[@moggy992]

Hi there this is a brill video for runners. I've recently bought a camelbak circuit for women spec for my nine miles plus up to the half marathon training. Just need a cleaning kit now. Nice piece of kit tbf.

[@jollyjollyme]

Very true about the water….thinking back me and the missus were the same

[@spacecowboy2070]

“Probably wasn’t Kipchoge asking about a water station on a 10k Facebook group” killed me - had to watch that 3 times 😂

[@Technik500]

Did Slough just get a mention on your video! Awesome!

[@andrewdelprete]

For long races with aid stations, I never bring water. For training runs over 10mi I’ll either set some water out or bring a bladder or some soft flasks in my vest. Usually only 500-1000ml. I never hold it in my hand though, I’m not looking for a bicep workout.

[@haiguyzimnew]

I carry a small flask when doing 10k or running for more than an hour. I hydrate during the week too, but it's just comfortable - psychologically - to be able to have a couple sips of cold water when running. I think a camelback is overkill for my use.

[@dangerdave138]

i appreciate your jeremy clarkson-esc humor

[@rhinopaul]

Iv never taken water upto 1/2 marathon. At first I was concerned because all I kept reading was that I should, then I just realised we are all different. I dont have breakfast either and I run on an empty stomach. It works for me and see more n more people doing the same now.

[@markfinlay422]

Very much this.

[@choof_worm]

Just started running, empty stomach is essential for myself also

[@runfargetlost991]

What was your half marathon time?

[@rhinopaul]

@@runfargetlost991 I'm a finisher not a racer. 2.21.

[@alberttresslevic914]

Same here. I've lost count of the amount of half marathons I've run fasted without water, must be over 50. Half of them would be slightly hungover too

[@creativeponderer9528]

Once again you are a lifesaver🙏. I’ve decided to run an 8 km circuit for as long as I physically can, be it 3 hours or 80😱. Every loop I can pop into house to vaseline up and get some nutrients and a slurp of moisture. No need to carry all that extra stuff🥳. Thanks Mark🙏

[@Bendersnatchling]

My health care insurance has a youtube channel where a doctor gives all kind of advice. One is about (de)hydration and he recommended to simply drink a glas of tab water (150ml) before your run and you should be just fine, as long as it's not way over an hour long. I tried that and it's so much more comfortable! Thomas Hellriegel, former Ironman World Champion of 1997, so above average, said in an interview he won't carry anything to drink for his 100km bike rides (3h) because he dreaded cleaning the bottle afterwards more than he would get out of it having something to drink. So while it probably makes sense to properly hydrate throughout the workout, if you don't want to carry water because it's uncomfortable or just to much of a hassle: don't do it.

[@Amundstvoll]

I tested running without water. After 18km, I was having balance issues. My normal run is 10km, so it might have just been that I was very tired. Still, if I'm planning to go over 10km, I'm bringing water...

[@Alniemi]

gotta listen to slim shady now on my new bone conductive headphones now that you mentioned it XD I 100% agree the gear obsession can be bad, I used to have nothing, and let myself go for years, now I am making a lot more money than I have in the past,. and im going HARD on the gear. You are very inspirational! I have all the pieces together and getting started on being above average, my last hurdle is the alcohol.

[@marksamson9229]

Agree 100%. And don't get me started on the con that is bottled water...
