Are you training for a personal best? What time do you think Sarah can run? Let us know in the comments!

[@jonb1107]

Sarah will run a sub 45 - her disappointment at 12 secs and determination will drive her on. I am looking to break 35 mins(35.45 pb) 10k, 1.18 (1.18.45 PB) half marathon before 40 next year.

[@lardus8614]

Sarah should go for 42 minutes next 😉 I may not be training for any PB, but I did do a leisurely stroll today and just so happen to have done my best time for a half marathon! Yes, it was road (yuck) and flat*, but I was close to doing it under 2 hours which for me would be an amazing time! *Netherlands is so flat! I miss the trails in South Africa 😀

[@jamie4u1431]

She would complete it in 43.xx mins

[@adamscales2376]

44:55.35

[@dineshjangir5450]

definitely she will run sub 35 minutes, she is seems to be fully determined and dedicated for continues improvement

[@xnij250]

Sarah has inspired me a lot as an average runner. Running my first 5k tomorrow and my goals are to finish the race in 30 min or 45 min or just finish it without walking. Thank you Running Channel for all your videos! Edit: Did it at 43min! Didn't expect the elevations in some parts of the route. I learned a lot more about what my body is capable of. I'll incorporate more hills and strength training next time so that I can improve my endurance. 😊

[@runningchannel]

Thank you Jinx and good luck for your 5k tomorrow! Let us know how you do 😃

[@JM-rm3lt]

Good luck to you!

[@rewod1644]

Good luck 💪💪💪

[@andrewcollier3495]

Good luck 💪

[@crowbar_the_rogue]

Good luck!

[@sigepohio]

These kinds of things are great. Watching someone, not just the highest level athletes, challenge their limits and see what they are capable of on the day. Brilliant! It's scary, exciting, nerve-wracking, thrilling, everything! Way to push your boundaries, you're on your way to your goals! Keep your eyes forward, mastery is a life long ambition. You have many years of growth and improvement ahead of you. Never know how far you will go unless you try.

[@eleanormorgan1891]

I actually felt a bit emotional watching this! It’s amazing how far Sarah has come since she first joined TRC, watching her do her first marathon, ultra and now an incredible 10k pb!! Well done x

[@souradipta]

In the last few months I have brought my pb down from 57 to 48.31.. now videos like this inspire us... where people like us...who are not athletes as such..push for their best and get there...thanks team TRC. Kudos Sarah

[@bighands69]

For many people starting out focusing on 3k and 5k times are more realistic and then using the 10k runs to help build that 5k time based foundation maybe a better approach.

[@78clarkkent]

Inspirational Sarah 🎉 Knocking nearly 3 minutes off your previous PB is insane ❤ Well done 👏 ❤

[@alexwoolley5173]

Could see Sarah was gutted not to break the 45 minute barrier but that was a bloody good effort! And an an amazing chunk off her old PB in conditions that looked far from optimal. Sport can give us highs and lows, it's never linear but personally, when I miss out on a certain goal I'd planned to achieve, it makes me more determined to go better the next time, you have plenty of time to reach that goal, very inspirational!! Well done Sarah

[@mabr6444]

Commenting on an old video here but I got freaking goosebumps watching this. Missing out by 12 seconds is nothing, like 1 second per K, which means that you where almost perfectly on pace which is a hard thing to do. Really impressive and inspiring!

[@hamba1998]

Well done Sarah, that's a huge new PB! I'm always impressed by how this channel is open about not meeting goals, and how it frames it in a positive way rather than as a failure. You'll get that sub-45 another day.

[@iainmacn62]

Half a second per lap! It's so happening very soon. Well done Sarah and thanks to all at TRC for a fabulous evening.

[@trasheaterpeter]

Amazing effort! You totally have it. I'm still after a sub-25 5k. I've failed many attempts but I've been, very slowly, chipping away at the time. Hugely motivated by your work Sarah.

[@jjsoledad8553]

Well done! I’m 56, 45 minutes has been my goal for the last 2 years, but life just keeps getting in the way. Current PB is just about 50 minutes, but more realistically run around 52-55 minutes. Mad props to you Sarah! Thank you for the tips.

[@sneharaju4791]

The running channel has inspired me so much. 9 months back I had my 1st baby & after a month or so of delivery I was not able to walk and had to start physical therapy. I was in the worst physical shape of my life! Watching your videos and the encouragement from my husband I started running again. Next weekend on the 2nd of Oct I’m running my first 10 mile race 🤗 I’m excited & nervous at the same time, I know I am capable of finishing the race. Running has helped me feel like myself ❤

[@runningchannel]

So glad you’re enjoying our videos Sneha! Good luck for you first 10 mile race 🎉 let us know how you get on!

[@tomthetaletellerphillips]

Amazing! Well done Sarah! 🎉 Just think, that's 1.5 seconds per km you were out by. That's so achievable! I ran a 20:04 5k and beat myself up that it wasn't sub 20 but then that's just 1 second per km and I did shave 3:30 off my PB! You've done so well, I am truly inspired. Now, if I was fitting multiple injuries I would be pushing for more PB's!

[@altosack]

Umm… It’s only off by 1.2s/km… (12s/10km). Back when I was running 10k every Mon/Wed/Fri and GPS on your wrist just wasn’t a thing, I finally broke down and measured my course (very accurately) with my road bike… it was 6.7 miles, not 6.2! Instant new PB!

[@TheDanami]

10K on the track is both mentally & physically tough, that was a fantastic effort Sarah & it's only a matter of time for that sub 45!!

[@chelseachristopher1585]

We fell in love with Anna and Sarah has now captured our hearts as well. Good job and well done!

[@monikaczng]

I always thought you were either a good runner or you aren't. Watching Sarah's journey along the videos has been so inspiring, currently working on getting my own 10k under an hour, and staying consistent with my runs! 🥰

[@brent_f]

Congratulations Sarah! 45 minutes and 12 seconds is still an amazing achievement. Kudos!👏👏👏

[@Bweyg]

That's basically sub 45 minutes. Just 2 seconds faster per mile pace and then she's got it!

[@alicespeedy98]

Had the honour of coming down on the day and can say it was an incredible evening!! Thanks so much to The Running Channel for organising it and congrats on your new pb Sarah - you’re such an inspiration!! 🎉🎉

[@runningchannel]

So happy to have seen at the event supporting Sarah’s attempt! 😄

[@bartb217]

What an inspiring video and well done Sarah. It was so hot that day, so I knew and predicted it would be hard to go sub 45, but you really did great and I am sure with better conditions you would have gone sub 45. I have no doubt you will break that barrier soon. I am training for sub 40 minutes after 4 years of close to no running. My PB, before I stopped running was 36 low, but I have gotten older, so I need some extra effort to get back in shape. I started running again 3,5 months back and after starting slowly am now at 4 times a week and 50km/week. This video gave me inspiration for my sub 19:30 minutes attempt in 2 weeks and sub 40 minutes attempt in 3 weeks time.

[@Liam-up3rv]

Congrats on your PB Sarah!🎉

[@SamHarrison2099]

Great video, and it was an awesome night too. Sarah and Andy both stayed around for ages to talk to everyone who came, they’re even nicer in person than on the channel! My big goal for 2021 was to run an ultra, which I did in July. Since then I’ve been training for a sub 2 half, which I am attempting tomorrow!

[@runningchannel]

Hi Sam, so lovely to see you at our event to support Sarah! Congrats on your ultra and good luck for your sub 2 hour half - let us know how you get on 😄

[@marcusgrainger3329]

Well done! This really makes me want to do 10k training again - that was an astonishing improvement in just 12 weeks!

[@CalmingAnxiety]

Wow, You are all so inspirational. Because of this channel and all the positivity I took up running again earlier this year aged 57 (after 10 years of power lifting). Next month I run my first Ultra!!! It won't be fast or pretty but it will be an incredible achievement for me. Thanks Sarah for your infectious smile,

[@jennic1684]

What a fantastic run by Sarah! I have signed up for my first 10k and expect to do it in double that time 😂 but I'll be happy to finish my first one.

[@robbiepenfold9318]

Really exciting conclusion. My 8yr old son has started running with me and is doing 3k twice a week. He loves watching your videos and it inspires him to train more.

[@Konsul135]

I started my training for a sub 3:30 marathon at the end of May next year just now, so seeing Sarah smash her PB in not-so-optimal temperatures is inspiring!

[@stewartsherwood7769]

Did the GNR two weeks ago not feeling especially in great form, expecting for maybe 1:30 at a push, somehow pulled out a 1:27:00. Was very impressed with myself. Did Lincoln half last weekend too, expecting about 1:35 as I was pretty broken from GNR, did 1:28:48! I think the cool weather helped so much, heat just saps so much energy. Sarah will smash that 45 soon enough!

[@adamfox2063]

I love these videos, motivating and inspirational, keep up the great work!

[@hollyandersen9394]

Congratulations! I am chasing a sub 2:10:00 half and have a current PB of 2:10:14. It can almost be harder to be so close than to be minutes away. Thanks for sharing your journey and the experience. Being in front of a crowd would definitely make it more nerve inducing when you are running alone. Looking forward to continuing to see your running journey.

[@quentinroberts7843]

I couldn't believe how emotional I got watching this- such an inspiring effort, well done Sarah 👏👏👏

[@JamesWester]

This was awesome! So much work. So much support. This is why this channel is great. Well done!

[@ThatGeekCatty]

So much love for this series!

[@stevie234]

Congratulations on the huge PB Sarah. I'm currently training for a sub-2:30 half-marathon. Long term is getting ParkRuns regularly under 30mins

[@andreta77]

Sarah, you are amazing! You were such an inspiration to me last autumn in preparation for my first marathon, and this 10K PB attempt is just something else! Good job and thank you for inspiring us to new victories!

[@sutrimfitness8181]

Well done Sarah! Amazing work!!! Such an inspiration 🎉

[@jmsanderson]

45:12 is bloody amazing for a 10k, look where you were when you started running and where you are now. Sub 40 vid in the future, wish i could have been there to cheer. Well done pacers too

[@mathesonrittenhouse]

12 seconds is a rounding error over 10k. A few degrees cooler and she not only hits her target she smashes it. Amazing job!

[@felishawood1904]

Incredible work, Sarah! Thanks for sharing your journey. So inspiring!

[@13tinytink]

Excited to watch you do this :-) Your journey has been incredibly motivating, so thank you! :-)

[@MajaNoer]

I hope you realized that a sub 45min is completely doable for you! And that’s the big thing to note! A few seconds over or under don’t change that. Weather does make a difference. Congratulations on the PB! 🎉

[@kyrioz]

As a beginner, I am guilty of the fastest 2k at the start thing haha. I always get carried away lol. Yesterday I got my new 5k PB (23m29s), 2 months ago I can't even do a sub 30min 🥺. Thanks to your videos, it inspires us non-athletes to do better. To all starters out there just like me just stay on track because consistency is the key. Slowly build up endurance then add speedworks. It does not happen overnight so stay consistent on your training ☺️ and please check your running form haha take care of your jointsss 🦵🏽🦶🏽

[@carolinephillips4116]

So so impressive Sarah. It’s amazing to see someone who is relatable achieving so much. You’ve really inspired me. Incredible work, especially in that heat!

[@daisydoo7575]

You did awesome Sarah! I love how you’re always striving to improve yourself. I know you were comparing yourself to 3 months ago, but I think it’s also important to look back on the last few years and see all the progress you’ve made. You keep on improving as a runner and your determination is so inspiring. I love the running channel! I’m nowhere near your speed or distance, but watching all the videos you guys put out has taught me that as long as I keep showing up I’ll improve! Thanks for giving us such good content!

[@jonrogers6418]

Found myself gasping for breath as Sarah crossed the finish line. Well done! Might not have been the victory she wanted but it is the inspiration that so many need.

[@adam7597]

I'm currently working towards breaking 35mins for 10k - did 35:00.03 just 11 days ago, new pb by a long way, but damn that hurt 😂. Sarah can break 44 for sure, how much lower depends on the distances trained for - I started 5k specific training and dropped from 18ish to 16:30 in a couple of months, so anything is possible 👍🏻

[@davidconsumerofmath]

ouch, sooo close! Better luck next time

[@isabelpaton5559]

Massive well done Sarah! Loving watching your running journey. Keep up the great content ☆

[@botakd6612]

Congratulations Sarah!! That's some achievement to cherish. Keep on rocking, you inspire so many of us!

[@DeeJay_78]

Massive congratulations on a new PB Sarah. Sub 45 is just around the corner, am sure of it!! Well done, RESPECT! ❤

[@Ckates]

You did freaking amazing! As they all said, it was a hot day/night and you were only off by such a small amount. Honestly, yes 12 seconds is 12 seconds…but it’s ONLY 12 seconds! You got down to that 45! We’re all proud of your hard work ❤ so inspiring!

[@geoffreylee8297]

CONGRATSS!!! SUCH AN AMAZING ACCOMPLISHMENT!!!

[@amythompson2488]

Great work Sarah! Loved this series, you were amazing!

[@wilsontang8995]

That was amazing and kudos to Sarah on her new time! These videos are inspiring! Thank you!

[@jayg1605]

Congrats on a smashing a massive new PB and also for another great series. It’s been awesome to watch the progress and learn a lot along the way!

[@jobrookes534]

Sarah, you're an inspiration to so many!! This is amazing well done x

[@lukemazzamuto6952]

Such a fantastic effort!!! Totally smashed it!

[@marcobach]

So close! You‘ve come such a long way and have been such an inspiration more so than some elite runner as what you did seems achievable to me as you show what you can get to when you put the work in. I’m sure the PB‘s will keep tumbling! Well done

[@gabrielsebastian1459]

The energy looks amazing, it's nice to see all this support and camaraderie. Great job Sarah!!

[@paulstirk4964]

Well done. Love watching all you guys push yourself, showing the good and not so good days, and being entertaining whilst doing it.

[@mellis.5928]

Wow!!🥳🙈 This really is an achievement, you and this whole channel are just inspirational😊😊

[@sagebrod]

I thoroughly enjoyed watching your journey, and although it was just a few minutes to us, it was months of hard work for you! I’m inspired to hit a 5K and 10K PB within the next few months. Thanks for sharing, and congratulations on your new PB! 🎉

[@knightrhonda7963]

Absolutely outstanding run 🏃‍♀️. Your commitment and consistency have shown through in a golden manner! Well done Sarah! 🇦🇺🌏🦘

[@zmbchclt]

An amazing effort, big kudos to you! I don’t think you’ll realise how many people you’ll be inspiring and giving them that extra push to reach their goals. You’ve reframed my mind on pushing myself to my goals and I thank you for that. Godspeed.

[@lemonpsi]

Love watching this series as I have recently just finishing working towards a sub 50 min 10K myself.

[@awest1838]

God! I cried 😭. Sarah you did so well. This is so inspiring. I’m having an hard time keeping up with my goal even though there are really important to me and this is the kind of videos that make me wanna go out and work on my goals right away. Once again, good job Sarah, this is definitely a win!

[@katrinachandler7174]

Massive congratulations on a huge PB 🛎️ All your hard training really showed, by knocking off a good few minutes. So inspiring! It took me 3 years to get a sub 45 minute 10km, it's hard work but worth it in the end. Keep pushing, know it won't take long now the weather has cooled down and you've recovered from Berlin
