How To Get Faster On Your Bike By Training With Power | Power Meters Explained

[@gcn]

Do you use a powermeter? How does it help you with your riding? Let us know in the comments 👇

[@lechprotean]

get some good readings, measure or at least accurately estimate your FTP and start doing sweet spot training. If you're new to structured training it will do wonders in relatively short time and without straining you too much.

[@VictorValderrama]

my smart trainer has it, and helps me a lot training for ultra distances ;) hopefully will set one on my bike soon

[@Second247]

Got it month ago. Hugely motivational and gives a lot more structured approach to my rides. Hilly terrain has alot more offer to me now than it previously had. Been riding year and a half, and main issue has been lack of reliable data and i have had no glue how i've improved over the time because conditions are almost never the same. Getting my watts helps hugely to put everything into perspective, both short and long term. As a strength athlete i consider power meter to be almost the same thing as knowing how much my plates weight on my barbell. Which is pretty basic information.

[@rafaelfranco7041]

Just started 1 year ago and realized I should've done it as soon as I could afford one. But I think that availability of information (i.e. internet) is what really makes power meters useful tools. With no knowledge on how to train with power then is just another number to look at.

[@andymiller3889]

Absolutely! I find they're particularly useful in helping me rein myself back when doing hill repeats. I finish in less overall time, with less maximum wattage, and feel better, as well. Worth every penny (I use Assioma Duo pedals so I can swap them easily between bikes).

[@fletcherchambers7175]

Love Ollie's *subtle* hour record attempt reference... "an hour full gas... Who wants to do that?". :P

[@bleckb]

Oh, I missed that. NOT!

[@MichaelMa]

You need a power meter, heartrate monitor, and a cadence sensor. I got each of these a year apart and while it provided good information, when you see all 3 working together and how it all effects the other, it felt like entering the matrix. You know what gear and cadence to be at a certain watt so your heartrate stabilizes in the aerobic zone so you can build up for a big anaerobic effort when required.

[@vvk]

I come from the world of trail/fell running. I was using a heart rate monitor for a few years but at some point I realized that too much information is just stressing you out. ( I remember switching off my watch when the alarm set for 180 BPM was constantly ringing during a 119km race in the Alps. ) So while gadgets could be a useful tool if you are a beginner the more experience you get the less dependent you are on equipment and gadgets.

[@macizzle1956]

Agreed! It seems like a waste of money to gather data that just tells me to ride harder ride longer. So effin what?

[@ronaldjimenez6556]

[@dwaynerandolph3565]

I was about to refer to the specifics of power while seated or standing & then tight at 14:50 of the video you addressed the topic head on. Well done mate ✔️

[@mattwolf4044]

Throughout the video we see clips of Ollie riding his red/black Orbea but if you look closely, at 20:24 there's a shot of Hank riding a red/black Dogma. This clip just so happens to come after a cheeky comment about how everyone will be so excited to hear all about your 5 watt gain. Very subtle - keep up the good work mates!

[@RLL944]

I got a power metre for my birthday on friday. Love it

[@TheMarman57]

I borrowed a friends bike which had a power meter fitted, and after zeroing it, I went for a 1 hour steady ride to see what I thought of the bike. Whilst out, I decided on the spur of the moment to go full gas up a 10% incline for around 100m. The power meter came back with approx 780 Watts for that effort - it was about 35kmh but by the time I got to the top, I was done. It's still the highest wattage I've ever pulled. I've just bought a power meter myself, and can't wait to fit it and get out on the bike.

[@paulignacius]

Very timely. Just started using my Faveros just a day ago. I'm lovin' it and indeed very useful especially for someone like me who goes to work by bike.

I'd love a video on how to buy a power meter. Seems to cost a million quid for the power meter, bike computer, and then you've gotta replace the either your pedals or crankset. Totally lost and feeling very poor having googled em

[@michaelrch]

Hang around on eBay patiently. But even then they aren't cheap. I got a 2-sided vector 2 for £350 after about a month of bidding. It's a good Investment if you want to improve and you can get the money together.

[@itnoked]

247MS1 luckily prices are coming down a bit, I guess it’s all relative! Decide: do you need a two sided (helps you spot asymmetries) or is one sided sufficient? What kind of bottom bracket & groupset do you have ? What’s your max budget? With those questions answered you should be able to pick amongst the main brands/models easily. Quark, 4iii, Stages, Power2max, SRM.

[@myklonsip]

[@henkki1000]

Then GPLama is your guy. Check his channel on youtube and also this list: gplama.com/powermeter-guide/ But if you don't already have a bike computer then get that first as well as a heart rate strap and cadence sensor and worry about power later. See what Garmin and Wahoo have.

[@HeatherSpoonheim]

Yeah - I picked up a Garmin watch with heart rate monitor so I could use it cycling and cross country skiing. Picked up a new fancy bike. Now I'm adding speed/cadence/heart rate sensors (heart sensor so I can put the Garmin watch on the bars as bike computer). Start of next season I'm going for a Garmin Edge. Maybe, if I save really hard, I can get the power meter by the end of next summer. I thought cycling was going to be a cheap hobby. Oops.

[@patrickenglish9593]

Ollie-enjoyed v much-thank you. I think it has been picked up in different ways in the other comments but it is worth correcting the stated maths-once calculating the work done you don’t multiply it by your efficiency you multiply by 1/efficiency , so 1/0.25 = 4 getting us close to 1 kJ = 1kCal

[@bramdoedijns4509]

You're absolutely right. Nice informative video, but it is a shame that the math is off. Also due to the this error yous should assume an efficiency of 25% instead of the 20% to be on the conservative side for weight loss, but who is counting calories anyways.

[@antrod4502]

[@ninaanderson9016]

Excellent video. Really well explained, thank you. I may be an ageing leisure cyclist, but I am off to look at power meters to work out my numbers and get better!

[@andrewlarkins4311]

19:50 I think you have things the wrong way around. You should assume 25% metabolic efficiency so that you do not over estimate calories used. If you assume 20% efficiency you would calculate a larger number of calories used. Apart from that it was a good video.

[@melembree8112]

No, do the math. Metabolic efficiency does not correlate directly to gas mileage in Ollie’s John Wick example. (418.4kj/4.184) x 0.2= 20 calories,

[@melembree8112]

(418.4kj/4.184) x 0.25 = 25 calories

[@chrisgregory7862]

Andrew is correct. There's an error in the formula - you need to divide by the efficiency, not multiply. 418Kj measured by the power meter is approximately 418 Kcal burned by the body.

[@gl3906]

@@melembree8112 kcal, not calories. anyway, as Andrew pointed out, you have to divide by the efficiency: energy input = useful work / efficiency, as the definition of efficiency is like: efficiency = useful work / energy input acc. to the laws of thermodynamics energy input >= useful work, otherwise you've invented the perpetuum mobile ;)

[@andrewlarkins4311]

It is interesting to note that gasoline engines typically 20-25% efficient much like a human cyclist! Just imagine the VO2 max of a 500 BHP engine.

[@Try_n_2Tri]

[@hobomnky]

19:02 you got the divides and multiplies mixed up. I learned the typical human efficiency is 20-25%

[@stephactiveveggiebyrd4275]

You explained it all well!! I have 3 different types of power meters on my 3 road bikes for at least 7 years and I love training to power training programs. I become stronger and focused for the season when I do.

[@marianneoelund2940]

That's quite the investment in equipment! I have one power meter, which is usable on only one of the 4 bikes I ride, as it's a hub type. I would love to have power metering on our tandem, but the only option is pedals since tandem cranks and hubs are special types.

[@huzaifahbaihaki4199]

I love GCN presenter's bike😍

[@xuchenglin6256]

There's a mis-spoke in 19:55, if you want to get a more conservative number of calories, you should use the higher number, that is 25% not 20%. If you use 20%, let's say, you worked 20Kcal on your power meter, you burned 20/0.2=100Kcal, use 25% you burned 20/0.25=80Kcal. The commonly used equation video mentioned, 1KJ=1Calorie, actually comes from the 25% efficiency assumption. Actually from KJoule to Kcal, you divide by 4.06, but the gross efficiency is 25%, you then multiply by 4. That's also what your Garmin uses. The divide and multiply roughly negate each other, so that it's roughly the same figure on the numbers.

[@p504504]

[@leeshirley14]

[@VictorValderrama]

the guy with the mullet just told you to throw your ego away 👌🏽👌🏽

[@Swampster70]

Powermeters are great for keeping you in check at the start of really long rides and for showing you the error of your ways. In one 400km ride, I couldn't figure out why I was so stuffed - until i looked at the data afterwards and saw that getting out of the saddle to keep the speed going up all the little bridges and overpasses (of which there was around 70) made it a 400km ride with 70 intervals thrown in. Not ideal.

[@walshman70]

After many, many years of happily riding without a PM I finally kinda fell into one on a new bike and I have to say I am surprised how much I like using it to guide my efforts. I suppose most cyclists are data hounds on some level right? I mean, I am no where near the athlete I used to be, but it is still fun to apply some of the modern training logic that is so much more available out there and understandable than in years gone by when it was all mysterious whispers and secrets...

[@gabrielmunoz9146]

this was such a great overview of training with power. thank you for putting this together!

[@thomascason2414]

I think that you guys could develop a great series of videos focused on how to continue to ride at a high level as you get "older" (read more experienced). I am talking about 50+ riders. We of that vintage still love to hoover up the county line sprints from the young bucks out there so I am sure it would be a very popular series. Get folks like Ned Overend to chime in.

[@eventaskibirkstis3963]

Thank u . Like your channel 👌👌👌👌👌👍👍👍👍👍

[@oliverracz2686]

I’ll argue that for non-competitive cyclists seeking to get fitter, a heart rate monitor is the better tool. You want to pace your effort depending on whether you have a better or worse day, how much you’ve had for sleep etc., and your heart rate reflects all of that, so it is a better indication of how your body is doing. Also as you get fitter over time, you will be able to exert more power at the same heart rate, and you can maintain a training effort relative to your own condition by maintaining your heart rate. For objective numbers, and comparing your performance to others, of course a power meter is better.

[@faabima]

When we have power meter, should we buy speed and cadence sensor too?

[@leedorney]

Torque is a good field to have on your computer and % of FTP which reads like a potentiometer whilst riding is really handy, forget the numbers/WATTS, they jump around like a spring.. Once you get an FTP it'll only vary if you're MEGA FIT so it'll generally be the same. Trainings a combination of Power initially, cadence then HR...measuring and pacing to a ride.

[@SRMUSA]

Great Video! Good explanations and you are focusing on the right aspects of training with power!

[@timothyc1985]

[@hahagager]

Most power meters cost more than my bike

[@JuniorBloxHD]

real

[@HeatherSpoonheim]

I bought a good bike. I picked up a Garmin watch with heart rate monitor. I'm adding Garmin speed and cadence sensors this month (oh, and heart rate monitor, so I can put the watch on the bars). I plan to add a Garmin edge for the start of next season. I'm thinking that by the end of next season I can add some sort of power meter. This is what I can afford, and when. When I bought my first bike, I thought I was going to be saving a lot of money by driving my car less. Why didn't you tell me!?

[@onilovni1234]

I had a power meter for 3 years, it was certainly useful but not necessary. That's why I sold it!

[@m.sspeckyy7494]

For cycling you just need legs pushing down the pedals, obviusly it is not necessary. It can help to improve faster, nothing more

[@michaelmartins8]

That ORBEA Orca looks slick!

[@dobby8]

Hi Ollie, you may want to check that formula on screen. You take the measured KJ and convert to Kilocalories by dividing by 4.2 divide by efficiency (not multiply) to gross up to actual work done by the body. Sorry the mathematician in me couldn’t bear to see that and not comment

[@marianneoelund2940]

Yes, the video was wrong and both operations need to be a division: First divide by 4.1868, then divide by efficiency (usually 0.2 to 0.25). But the end result isn't "work done by the body," it's "calories consumed." The work done by the body is the original KJ figure. For anyone who is at 23.88% biomechanical efficiency, the figures for KJ and calories consumed will be the same (using "dietary" calories which are technically kilocal). Most well-trained cyclists fall into the 23-24% range. For less-fit persons who are at about 22%, the calorie figure will be 8-9% higher than the KJ figure, and for sedentary or untrained folks at about 20% efficiency, the calorie figure will be 19-20% higher than the KJ figure. But studies have shown that efficiency can be as low as 16% when obesity is present, even in youths. That is fortunate, as it means seriously overweight persons can burn more calories at the same power output.

[@Mortinar]

It would be interesting to do this kind of video with a cheaper power meter, most of the people that use this top-end gear already know how it works and how to train, this crank set/powermeter combo alone cost more than what the average ful bike setup do.

I like the fact that you differentiated between doing a FTP test on the flats compared to doing them on a hill. I dont think doing them on a hill is as real world as opposed to doing them on the flats. Cadence I think is another factor that should be considered as well. If you typically spin then your test should reflect a good rpm otherwise if you grind it out for the bigger numbers than those are not likely numbers you will hold for an hour.

[@jafackl]

[@MrBJPitt]

A cadence sensor isn't a power meter.

[@MyFreeVideoServer]

@@MrBJPitt True, but it at least shows a piece of the data a power meter would provide. I feel there was a solid 30s of this video that pertained to me, lol. I'm just excited for all the boxes to be active on my Wahoo app during my next ride. Sure, it's totally unnecessary, but the geek side of me is pumped.

[@darrylhuculak4996]

Yes, by all means, talk about your power numbers. Then watch as your friends put those numbers to the test by trying to ride away from you as quickly as possible. Makes for some great interval training.

[@MggW]

I'd be really interested in tips about how to carry out tests outdoors - in finding a route to ride, what am I looking for, how far from home to get in a warm up? Also, these often ask for a target FTP ahead of the test. Some tips on how to select that number would be good!

[@James-zu1ij]

I guess my ftp is 300 so I do 375W unstructured intervals i.e. I add up my time riding at 375W e.g. 30 minutes. So I ride up and down a dual carriage way for 90 minutes until I get a total of 30 minutes. I hardly ever go to failure. Then one day I decided to test my 20 minute power for the first time. So I guessed at 330 - 350W as something to keep nudging. I managed 337 W for 30 minutes and I always felt I had to keep holding back (Hr 160) I was always scared to test my self as sometimes it felt hard to do 2 minutes at 300W But this type of training seemed to do the trick. I am 60 yo 83Kg I do 3 X 29 miles fast commuting per week. One thing I have noticed, it's quite hard to go that little faster. My goal this year is to do 400W for 5 minutes I can do 375 quite easily but getting that extra 25W seems impossible. I think it's just a question of keeping the power at 400 as I tend to aim for 430W to average 400W keeping power low but CONSISTENT seems to be key to getting a high average power and hence a good average speed. Just my experience as a numbers nerd with no life. Hope this helps someone. Hope to get into chainganging soon then it repeated accelerations of 750W uuugh!!!

[@grahamknight4471]

@10:40 Ollie says he can produce a better 5 min power on a climb than on a flat, I find the same thing with my climbing power way above what I can do on flat. Can anyone explain why this would be?

You never explained the advantages/disadvantages of different locations for power meters. Any chance in the near future? Thank a lot!

[@Quagmire17000]

I know old video no one cares but I'm pretty sure you need to divide by the efficiency, not multiply since your body needs to use 4 or 5 times (0.25 or 0.2) the amount of energy (calories) to produce the power you measure with the power meter

[@MatthewAtkinson]

Idea for the next video: Calories burned and efficiency. When it's 100F outside, my body is working much harder to maintain 98.6F than when I'm inside and it's 72F. So when I am on the bike and the power meter says I burnt 500 calories when it was 72F and 500 calories when it is 100F, how many more calories did I burn when it was hotter? Over an hour I bet this adds up a lot. I'd also guess that some people are much better (efficient) at maintaining 98.6 than others.

[@denisspratt926]

Norwegian rider Carl Fredrik Hagen actually drops the powermeter for the Giro. He will not use it due to weigth. The Ridley bike Lotto Soudal uses are a bit heavy he thinks. Hope he does well in the Giro. He was great in the 2019 Vuelta. And personally i don't care for them. I feel that the pro cycling has become a bit more boring after they started using them in races. So it's not for me. Keep up the good work.

Would be good to get a follow-up on this perhaps coupled with The 1000 watt challenge on setting the typical 6-7 power zones seen on devices with your max effort results for 5 s, 1 min, 5 min etc instead of their usual % FTP based zone. Asking because my FTP is ~200 but my 5 s is 1200 and 1 min is 400+ so zone 7 120% FTP of 320 doesn’t seem right?!

[@Try2Tri]

I beg to differ on your opinion of HR versus power. It's true HR is variable given the environment. It is however also known that the physiology of your body is also variable. This means that when you train purely based on power you will have a different training effect given different environmental conditions for the same power. I do some training by power and some by HR. Ideally I would always have information on both, but there is no reason to prefer one above the other, it's always a combination of both.

If you want to improve something you have to be able to measure improvements in it's smallest increments.

What about calibration without a button?

[@itaybruck9671]

I ride with a Garmin Fenix 5x plus watch, a Cadence sensor and a Heart rate strap. When my ride is shown on Strava, I get an average power calculated by Strava. I wonder how accurate is it. My age and weight are known by my Garmin connect app. Has someone compared the calculated average Power to the power measured by a Powermeter?

[@HeatherSpoonheim]

I'm going for a similar setup - just have an older Garmin watch.

Depend on Too Much Factor the number it give me on my Gravel bike was 50-60% lower than my powermeter. But if guess rolling on 40mm tire on dirt is n'ont the same effort /speed than 25mm on pavement!
