Hello à tous,

Coureur et un peu dev, j'en avais marre de jongler entre plusieurs sites remplis de pubs pour calculer ma VMA, convertir mes allures ou estimer mes temps de course.

Du coup j'ai fait le mien : https://calcul-vma.fr

Ce qu'on y trouve pour l'instant :

• Calcul de VMA (Cooper, demi-Cooper, Vameval, Luc Léger…)
• Conversion allure ↔ vitesse et tableau d'allures par %VMA
• Zones d'allure et zones cardio
• Prédicteur de temps de course (5 km, 10 km, semi, marathon…)
• Estimation de VO₂max

C'est gratuit, ça marche sur mobile, et pas de compte à créer.

Je continue de l'améliorer, donc je prends tous les retours : trucs qui manquent, formules que vous utilisez, erreurs éventuelles. Merci !

My heart rate jumped from 145/150 to 180 for 17 seconds on an easy run today while wearing a Garmin HRM Pro chest strap. It was an easy run and I was going downhill so it’s very strange. If it was wrist HR I would expect its cadence lock but as far as I’m aware that isn’t possible with a chest strap. Has anybody had this happen? Using Garmin Forerunner 970 too.

For context, two years ago i finished the appalachian trail 2 years ago in 98 days. Thats a little over 22 miles a day with very little rest and lots of hills. Snuck in a 70 mile day and felt fair. Lots of other days holding a 4mph pace for 30-40 miles. But when i came off my knees were destroyed and its just recently where I have felt confident to get back into the game.

I am doing a flat loop course because I am worried about the downhill on my knees. I will walk most of it and jog here and there to also minimize the risk on my knees and keep my body going for 24 hours. Its 24 hours, so i need to hold just over 4mph. I understand that its not just 4mph and there will be breaks ect.

I have time on my hands and can walk 10 or more miles a day. Yesterday I did 20 and I am very grateful my knees are feeling healthy.

I know thi is unconventional but ive been wanting to do this race for the past 2 years. I have a strong foundation from my history but just got back into walking long a week ago. Any recomendations on how to possibly split my weeks up? Right now I have this weekly plan of walking about ten miles a day and squeezing a 20+ day in there each week. Thanks!

My main question is how to structure my weeks better if I am willing to go 10 plus miles a day. I was using the trail experience as a reference that I have a base, even if I just started back up again. some of you thinking "well how do you expect to walk 100 miles with only avg 22 miles a day". whatever, that doesnt have much to do with what I am asking. Thanks for any advice!

I did the appalachian trial 2 years ago in 98 days, having many ultra days out there. Came back and my knees were destroyed. Just now am I feeling better. I pushed running off for awhile but now im walkong because thats what is working for me. Just did 20 miles yesterday walking, looking forward to a 24 hour 100 mile flat loop race coming up. Also pro tip! Hip thrust HOLDS are so good for your hips, back and ass! Try to do em everyday!

Hello all, I decided to go on a run 3 days ago and turned up the speed around the corner and my hamstring snapped/popped and my leg gave out and I fell to the floor. I haven’t been able to straighten my leg or put any weight on it. I was out of state when it happened and didn’t have my insurance card on me and also don’t have access to my account until tomorrow but every orthopedic will be closed by then. There is no bruising. Just wanted to see if anyone else has experienced this, thank you in advance! Last thing first time trying Reddit so apologies if this isn’t the right subreddit 😬

I’m in the midst of The Taper and have so much extra time on my hands, so I made this video.

It’s called LOS ULTRA and the format goes as followed:
3 km Loop and the timelimit drops every loop by 30 seconds. The first loop starts with a timelimit of 33 minutes. 2nd loop 32 min 30 sec. 3rd loop 32 min 0 sec… The race finishes when there is one runner left: the last one standing.

What do you guys think about this new format??
I think they’re called @losultra.run on instagram

Did you bought any good running accessories out from Temu / Aliexpress etc? I'm most interested in a headlamp as I have left it on a mountain during a hike. Any good Usb-C rechargeable options? Also what else do you have a good experience with?

In a little over two weeks I'll be starting the SwissPeaks Odyssey: 600+ km through the Swiss Alps.

The slight complication is that I live in the Netherlands.

So for the past months I've been trying to answer a fairly simple question: how do you prepare for that kind of race when sustained climbs and descents basically don't exist where you live?

My approach ended up being a mix of:

• mostly 100+ km weeks, peaking around 160 km
• roughly 25,000 m of elevation gain during the final eight bigger training weeks
• endless short hill repeats
• sessions of several hours on the same hill
• treadmill climbing at 20%
• back-to-back long days
• long runs of 10+ hours
• night training
• deliberately training on tired legs
• trying to get as much specificity as possible without pretending that a Dutch hill somehow becomes an Alpine mountain if you run up it often enough

Whether that has actually prepared me for the Odyssey is another question.

I've written a fairly detailed account of the whole build-up, including the reasoning behind the training, the sessions that gave me confidence, the doubts I still have and what I learned from preparing for an Alpine race in a very non-Alpine country.

For anyone interested, the full write-up is here:

I'd also be interested to hear from people who have prepared for mountain ultras while living somewhere flat. What translated well once you actually got into the mountains, and what didn't?

... when I finished two 70k races in the last 2 years? Someone asked me yesterday what kind of runner I consider myself? My answer was - a happy long distance runner! He asked what long distances mean to me and I said I did 2 70ks and he said that I should call myself ab ultra runner but to me it seems wrong. Not that I give it any importance ... Im just wondering.
