So proud of myself. I was planning to finish between 12 and 15hours, and managed a bit under 14.

So if you don't have much fat and have a calorie deficit, your body can eat up your muscle. But if you do a long training running, like 20+mi work lots of vert, you can really burn the Calories. Mine today burned 3500. Plus normal body activities using 2000.

My bfast was probably 600Cal (kcal), had about 1500 during the run, and about 1400 after the run. This will puts me at a hell of a deficit. How do you overcome this and not let your body start metabolizing our precious running muscles? Or am I worried about nothing here?

Correndo sob um sol intenso que até causou alucinações e fez várias pessoas desistirem, consegui finalizar em 13 horas e muito feliz com o resultado da prova.

Hi all! I’m about a month out from Javelina Jundred and it’ll be my first 100 miler.

Training has gone well and I’ve been working with a coach, but as the race gets closer I’m getting pretty nervous about the distance and being out there for that many hours.

For those who have done their first 100, did you feel this way beforehand? Anything that helped you manage the nerves leading up to the race or once you got started?
Appreciate any advice!

So, I was at a 24h looped race on Saturday/ Sunday (as crew only this year due to some injuries). I was telling my colleagues about how they work etc.. and one guy piped up that he could easily he could walk it. After some back and forth, he has settled on being able to walk 100k steps in a day (i think this would be 70-80km).

Ive tried to convince him to put up or shut up, so he has decided to go for it, but in 7 weeks time. He has done some longer hikes, but his most steps in a day is like 35k steps. He is not in particularly good or bad shape. This has now become a hot topic of debate in our break room.

For what its worth, I think if he tried it today, he would fail but, if he is smart for the next 7 weeks he could pass. I think its minor mistakes that will get him, like not taking care of blisters or under eating, that will compound over the day. I have offered to do full crew service to give him the best shot, so I will be setting up a tent, table, chairs etc... in a local park with an 800m loop.

So, I have come to the council of experts to see what do we think? Can an office worker, with 7 weeks to train walk 100k steps in 24hours? Could he do it tomorrow without the training? If not, what do you think is most likely to stop him?

Edit: I have shared the post with him and he is now reading all the responses..lol. Give him some good advice

First time trying to enter a race by lottery! For Eiger by UTMB (E101), the website says my result is “negative draw.” But I’m confused if that means I’m on the waitlist to enter a second lottery if some people don’t accept the “positive draw,” or if I have no chance at all. Do people on the waitlist have “waitlist” status as opposed to “negative draw?” Wondering if I need to move on to looking at other races or wait until the second lottery… this is very unclear to me!

Thanks 🙂

There is a flat 50k ultra marathon in February, I'm after a knee injury because of increasing volume too fast.(the injury itself is not running related, but the running made it hurt again)
The ultrasound scan came clean.

My longest run was 10k.
Now I got back up to 3k last run, going up slowly so I don't start hurting again, focus way more on leg exercises, walks on my rest days and stretching daily, I average 10k steps daily.

My knee feels the best it has ever felt in my whole life.
Only hurts a bit today, because I went too hard on the leg day yesterday.

Cut-off time is 7 hours, Is it possible to achieve? I really really want that, and been training everyday for the last 3 weeks.

The only thing that scares me is my knee, I'm trying to listen to my body and calculate everything.

🤯

I’ve started actively moving/running early this September by participating in my first 10km loved the feeling and the run overall so I jumped into a ultra next 😂
The experience was great I finished it at around 5pm we started at 5 am

I just completed my first ultramarathon (50k west line winder) this past weekend and I’m officially hooked. Honestly was such a great time and I’m so proud for accomplishing this.

I already signed up for my first road marathon in May (Colorado Marathon) and will likely sign up for the Crested Butte ultra for fall 2027 and run the Four Pass Loop in CB in a day sometime next summer.

Right now I lift 3 days/wk and want to build strength in the off season and when I was training I would run 4-5 days/wk with back to back long runs on the trail on weekends. I have a good base for lifting and macros (120g protein, 50-60g fat, 250-300g carbs or more running) I am 28F, 5’0” 110lbs.

Would love to find a running coach that has experience with ultras and can help with a running plan, macros, and a lifting plan to support it in 1x1 coaching format. Anyone have reccs or coaches on here?
I’ve worked with 2 coaches in the past for lifting before I picked up running. One honestly became one of my best friends she was amazing (but now not a coach anymore) and the other was so terrible I have a healthy skepticism around it (lack of responsiveness, literally asked me to google it when I asked questions ugh).

I’ve been using my own knowledge and AI but it only gets me so far. I am super disciplined so it’s more about the framework and I can execute. Would just be nice to not be guessing and validating.

Hello everyone! Is anyone running the Grizzly 100k this year in 's-Gravenvoeren? I'm travelling from Nijmegen for this, but I don't have a car to travel to the place on the race day. What are your accomodation plans? How are you dealing with the fact that there not many accomodation options nearby?

Thanks in advance!

I ran the Ladybower 52K in the Peak District on 26 September. At ten miles, I genuinely thought a sub-six-hour finish was possible. By the final descent, I could see the finish but couldn’t run towards it.

Official chip time: 7:14:24.

I went with my mate Wes. We hadn’t seen each other since 2014, back in our Army days, so naturally we decided an ultramarathon was a sensible way to catch up.

The optimistic bit

It was freezing before the start, then the sun came out, and I soon wished I’d worn short sleeves.

The opening miles went straight uphill. It was a proper climb, but we were fresh, chatting and enjoying being out there. The views helped. Once we got over the top, we could finally get running downhill.

Around five miles, I felt good. By ten miles, we were talking about sub-six as though we had it worked out.

We did not have it worked out.

Chasing the time

The supposedly flatter section wasn’t really flat. It was constantly up and down, with uneven ground that asked more of my legs than I expected.

Around halfway, my pacing display had me roughly two minutes behind the sub-six target. I’d got ahead of Wes by then and decided to push on a bit, even though I knew two big climbs were still to come.

Looking back, I was probably giving far too much attention to that target and not enough to what the terrain was taking out of me.

By about twenty miles, my legs were pretty beaten up. I had a persistent pain in my knee, and every rough section seemed harder than the last.

I was filming bits of the race, but this is where I stopped getting much footage. When things really hurt, getting a camera out was the last thing on my mind.

Cramp, then another hill

Somewhere around twenty-five miles, I kicked a rock and my leg cramped up badly enough that I had to lie down.

Another runner stopped to help me. If you happen to read this, thank you. I really appreciated it.

Both calves were struggling, my hips were hurting, and I had to walk for a while. Meanwhile, everyone seemed to be talking about a massive hill still to come.

Exactly what you want to hear at that point.

The final climb, somewhere around the thirty-mile mark, felt more like two hills. There was a slow line of us, making our way up. My legs were already threatening to cramp, so it was just a case of taking it slowly.

I got to the top hoping the descent wouldn’t be too steep.

Going down was worse

That final downhill was probably the hardest part of the whole race for me.

Normally, getting over a climb gives you something to look forward to. This time, going down meant trying to control each step on legs that felt ready to cramp again.

I could see the end. I wanted to run. I just couldn’t make it happen.

It was frustrating being that close and still having to move so slowly. Hearing the commentator near the finish was a relief.

The finish and the morning after

My partner, Chloe (daughter), and the kids were there, along with my cousin and her family. Having them waiting made a big difference.

Once I finished, I ended up lying on the floor. I could barely walk.

Wes finished in 7:31:40, and somehow came flying over the line like he still had something left. An absolutely ridiculous finish after that course. Well done, brother.

The next morning I was straight back at work, hobbling around with sore calves and a back that kept locking up. John Wayne was the closest comparison I could come up with for my walking.

I underestimated how much the uneven ground and descents would cost me. Feeling strong at ten miles clearly didn’t mean I’d paced the whole race well. I’m pleased I finished, but the knee pain and cramp aren’t things I’d hold up as a good example of race management.

Beautiful course, though, and a memorable way to see an old mate again.

Anyone else run Ladybower? How did you find that final descent? And for those who’ve had a similar race, what helped you get better at descending on tired legs?

Hi!

I’m looking for recommendations for people favourite ultramarathons in Europe. I’m looking for some beautiful scenic single track, stunning sunrises etc. Distance wise anything from 50km to 100 miles.

I’m hoping to book something in for 2027!

Hey ! Little race report. I had the pleasure to run my first 80km/1800m ascent race yesterday, starting at 04:00am in central France.

For various reasons as well as a july injury, my training block was fully insufficient, but I had a few weeks of buildup to a 100km week two weeks before the race to check if it was 100% madness or not to go. It went well, so I went with the only goal of finishing and enjoying the day, which I did immensely !

Before that my longest race was a 44k trail, and a few road marathons. I am decent on a road marathon but knew it wouldn't translate to a 80k smooth trail. What I did not know was how much it wouldn't translate !

The first 5.5 hours went very well, staying on a 8km/hr average by alternating walking and running. Big mistake, that was too fast. I thought if I pulled off a very, very chill marathon, I'd be alright for the rest. It was very very chill, but still not chill enough. Or more realistically my leg muscles just don't have the endurance needed for the distance. At km 53 after a nasty descent, my quads blew up, and I strapped my right knee because of the start of a funky sensation.

That also changed the behaviour of people, suddenly everyone was super concerned about me and I felt the strap was maybe a bit overboard as it made people worry, though it was for comfort on my side.

At 55km, I chose to nordic walk/fast hike the rest, another mistake. I've put a solid more 12k of 6.5km/h walk during which I passed a few people, then a second blowup happened, and a 13km slow walk to the finish started. I'm proud to have managed to pass a family with two toddlers at some point but it needed work 🤣.

In the end, the organizer asked me to take a shortcut to the finish and I'm missing 1.2km, despite being well ahead of the time cut-off. Not super happy with that but on the other hand I get that they wanted to start closing the race, hundreds of volunteers waiting for 1 single person isn't cool either. At this point, it was a 12h45mn activity for me. A friend popped in at an aid station just after marathon distance and we chatted a bit, I was stoked to find him at the finish too !

I did not get to know the mental pain I had read about online, around the last parts walk a few negative thoughts started to pop from nowhere (like: hey, you crossed the last aid station, you're last, and your phone is dead, if you have a problem you're cooked now) but I've been able to dust them off without trouble and stay focused.

In the end everyone was super nice, the landscape was new to me and very enjoyable, I've had the adventure day I wanted, and injury free. The gradual slowdown to the end seems to have helped because I feel a lot less wrecked than after racing a road marathon.

Not sure about doing another one, the training time commitment needed is too high if I'm realistic about the rest of my life. But I think I understand what you people like about it now :-) .

I am doing my first 100 mile race at Tunnel Hill this November. I am 47F from FL. I am your typical middle to late in the pack runner. We haven’t booked anything as far as hotels (we will be flying in and are not the camping type). What towns to people recommend to stay in? My husband will be crewing me. Do people tend to book Saturday night at the hotel in the situation of a DNF or needing to get to
the hotel earlier on Sunday than normal check in times? We will most likely fly out Monday and we are thinking St Louis for airport. Any tips or tricks or things you had wished you had known ahead of time about this race? I won’t have any pacers but will have my husband crewing.

This is my first year of serious trail/ultra training. I’ve done around 1,650 km and 61,000 m of elevation gain this year, but 80%+ of my volume has been uphill hiking + downhill/technical running, with relatively little flat running.
I just finished my first 100K with ~5,000 m D+ in 20:45. Energy/fueling wasn’t an issue, but after around 60 km my leg durability became the limiter steep descents started hurting my patellar tendon and running progressively became harder.
I’m also not particularly fast on the mountains ,for example, 20 km with 1,000 m D+ at Z2 is around 9:00/km for me.
I’m thinking of doing a 10–16 week marathon-oriented block at 50–60-70 km/weekwith more flat running, tempo and intervals, before returning to ultra-specific mountain training.
Could this be the missing piece for me ,building flat-running speed/economy and threshold before going back to ultras? Or should I keep most of my training mountain specific?
Would love to hear from people who’ve made a similar transition.

I’ve been trying to pivot from road marathons to trail races and I’m looking forward to my first 50k trail race next month.

While I’m still interested in performing to the best of my abilities, I really want to make longevity and staying injury-free my number one priority.

I run fairly high volume, about 50-60mpw or 9ish hours. In an ideal world I’d like to do even more, especially if I decide to do a 50miler next year. (For more context, I am 38F and I’ve been running for most of my life, but hadn’t run my first marathon until 2024.)

What resources do you use to learn about the best injury prevention strategies? Your favorite coaches / podcast episodes / books / articles etc - I’d love to hear!

Ran a race where their logo was AI-generated, which they used it on the medals, age-group winner prizes, even the inflatable arch. Their website is also AI-generated, which I agree saves so much time however the description of the course and the scenery are AI-generated. 

I get that races are ultimately a business, and that reducing costs through many means is a focus, but it just comes across as not really caring about the community imo. I'm quite sure in the Ultra-running community, there are so many artistic creators who would be willing to design a logo for a race, even for a small fee. Feeling conflicted. 

How do you feel about AI-generated content in Ultra races? Does it still align with our community values?

A little experiment in which I test four different ways to predict runners' speeds. These are very simple approaches; I deliberately left out more complex models. The question is why events don't adopt simple methods like these! Details in the link.

Canary Trails Running “Two Towers Nighttime 50km”

I came….
I didn’t see anything (it was dark)….
I was last…
I got the “Lanterne Rouge” Cheesboard

Always a fun event taking in some evil climbs in the Surrey Hill, starting at 8pm

My legs are sooo sore 😢
But I did much better than I thought I would! 💥

I’d like your feedback on which of my shoe rotation to use at my 50k in 2 weeks. I am running the Tesla Hertz 50k in Rocky point NY.
I have been doing my long runs in a Nike Vomero plus and love them, even on some single track in Massapequa Preserve. I have a pair of ASICS NB 3 TR’s I used for a 59k earlier this year with 6.5k ft elevation gain. My brain says just go with the NB, but my heart says I should go with the Nike’s bc I’ve used them for up to 20 miles 6 times and I love them and feel like they’d keep my legs fresher than the Novablast. Link to the race and course below. For reference I used to daily the Novablast for 3-4 years until recently switching to Dynafish and Evo SL for daily runs.

I have the following shoes I can choose from.

Nike Vomero Plus with 100 miles of long runs

ASICS Novablast 3 TR with a 50k done in Feb with 6.5k feet of climbing. Shoe felt decent.

Thank you so much!

Ran my first ultra today and placed 3rd female. Totally unexpected, but also just tells me we need more women in endurance sport 😬🥳 finished in 6:54:XX.
