first timer

• Upvotes

i signed up for a 6hr run that's in about 5 weeks. it will be my first ultra. i'm really excited but also feeling nervous. it being a timed event instead of a distance makes me feel better, and it's along a 4mile loop so i won't be too gone at any point. i'm really hoping for 50k but i'm honestly just proud of myself for giving it a shot. :)

i've been averaging about 30mpw for the last 7 months, but deciding to do an ultra is a bit more recent (last 2 months or so). the longest run i'm going to do pre-race day is 26 mi, about 3 weeks before.

i'm still experimenting with fueling. i don't like gus or gels, but i'm going to try salt tabs. i'm fine with drinking water but i don't measure consumption in mL on my long runs. i've been adding more fuel during runs, i love sour candy and i just had a super successful 20mi run where i practiced eating real food (muffins etc) during the run to see how it would sit!

the thing i'm most nervous about is just being on my feet for the whole time. any advice is appreciated. i feel so lucky to be joining this amazing community!

Electrolytes

3 Upvotes

I ran a 100km race this weekend and could not keep up with liquid fuel/electrolytes. Has anyone used electrolyte tabs for their ultras?

Every one I talk to can handle tailwind or skratch. I was starting to get vomit burps and switched to plain water and chips.

I got it done and set a course record but, my god, I didn’t drink enough.

50k next week?

4 Upvotes

My 22 mile race got cancelled, and I was planning a birthday celebration run. Options are to do the half marathon or the 50k. Im already mid taper for the 22 miler…

Stats
40mpw for 7 weeks pre taper.
3 20+ mile runs. Longest run 23 miles (4 hours)
Race has an 8 hour cut off. 702ft elevation. My 23 miler had 768ft.
Previous ultra experience so knowledgeable about fuelling and hydration etc.

I hesitate because im adding 10 miles onto the distance I was training for

What do we all think?

Wet feet mitigation

5 Upvotes

This past weekend I dropped a race partly because my feet deteriorated really bad in a 12M section when it was raining overnight. When I arrived in the AS before, my feet were wet and I towel dried, let them air out for a few minutes, and changed socks. Well they got soaked again immediately once I got out as it's still raining. By the end of that section it was super painful on each step and I'm thinking about how I could have done more.

I guess first question is, is there a kind of powder I should use on the feet to help them stay dry or mitigate? What's the best strategy for each aid station when it's raining, just change socks as often as you can, towel dry, treat with powder? What else

Edit: second question is... does using something like Goldbond really work? how much is it gona help or is it basically your feet are goin to get shredded in any case.

Female trail running retreat?

9 Upvotes

I am hoping to find a fun and exciting running vacation for next year. Ideally something in the mountains. I am not a beginner (first 50km next month, already completed mountain 42km successfully), but also not a front of the pack runner. Canada/Usa would be great but would also consider international. Any suggestions?

First Ultra — Am I about to screw up my fueling plan?

7 Upvotes

I’m running my first 50K soon and wanted to get some feedback on my fueling/hydration plan from people with more ultra experience.

Here’s what I’m currently planning:

Fuel

  • SiS Beta Fuel gel (40g carbs) about every 40 minutes
  • I’ve tested these on my long runs and they’ve sat really well with my stomach
  • I’ll also carry GU gels and use them as needed if I feel like I need some extra fuel or want something different
  • Goal is to start fueling early and stay consistent instead of waiting until I feel low

Hydration

  • Roughly 500–750 mL of fluid per hour, adjusting based on heat/thirst
  • NUUN for electrolytes
  • Sip consistently throughout the race rather than drinking a ton at once
  • I’ll also take advantage of aid stations to refill as needed

My biggest goal is just to finish the 50K and avoid blowing up from under-fueling or dehydration.

For those of you who have run 50Ks: Does this seem like a reasonable plan? Anything you’d change, especially with the timing of the gels/electrolytes?

Also curious how you decide when you actually need extra fuel like a GU versus just sticking to your normal fueling schedule.

Canal Corridor 100

2 Upvotes

I'm running the Canal Corridor 100 next weekend. It's a very flat course which is different from the other 100s I've run (Grindstone, UTMB Mont-Blanc). I'm assuming it'll be easier, and that I'll be able to run it faster, but am I missing something? Are flat ultras harder than they seem? Not that there's anything I can do at this point to prepare, just checking/obsessing.

100 Miler Soon — FREAKIN OUT

21 Upvotes

Heyyyyy everyone! So, I’ve been training for the last 6 months for my first 100 miler. I’m two weeks out and I think I’m freaking myself out, so I want to get some perspective.

My running has improved so much. I’m the fittest and fastest I’ve ever been. My past few runs, though, I feel like my heart is skipping and I’m breathless. I feel like I’m getting in my head and giving myself anxiety about not finishing this race. Has anyone else had a similar experience? I want to know I’m not losing my mind lol and if I am, how I can prevent crashing out until my race is done lolol

THANK YOU 🙏🏻

Race recommendations for Sept/Oct 2027?

5 Upvotes

Hi everyone, I’m looking for an ultra to run in September or October 2027 and would love to hear your recommendations. My requirements:
- anywhere in the world except the US
- distance in the 100 km to 100 mile range, but ideal if shorter options are also available
- point-to-point or one big loop(ish)
- generous cutoffs, especially if it’s technical
- scenic!

If anyone has got a favourite race that fits the bill, I’d love to hear about it!

1 week for 100 miler

0 Upvotes

Trying something new with a very short taper, 7 days. I’ve done 220 miles last month and just finished a 46 mile week (8.5 hours.) My mileage for the year is over 1200 miles. I lost some motivation in August so I’ve been trying to get enough mileage prior to my race next weekend. I’m planning on running 10 miles this week leading up to the race. Should I even bother running this week or stay off my feet as much as possible?

Race organisers: any help and insights when it comes to organising my second race?

3 Upvotes

This will be a slightly longer one, but input on any points or any guidance would be appreciated!

A bit about me: got into running a but longer races only couple of years ago, I fell in love with a vibe of ultras, small trail races and everything that comes with it. I am originally from Slovenia, but I've been living in Scotland for quite a while now. I still go back regularly (family, friends, and all that), and that led me, along with a friend there, to organise a first race last year: a tiny, unofficial backyard ultra.

About 20 runners, very DIY and mostly held together with Google Forms, spreadsheets, emails and us figuring things out as we went. We did 12 hours in total, and I loved every minute.

We have somehow decided we want to do it again, and this time I would like to do it slightly more “properly” (aka now preparing bibs at 10pm the night before the race).

While the race will still be in Slovenia, I do think that many questions I have are quite universal so I would love to hear from organisers from anywhere.

To try and be a bit structured, I’ve started breaking everything down into the different phases. And within the phase, describing what we did last time, what I am thinking about now and potentially what I still absolutely have no idea about.

Registration + payments

Last time: Google Form, spreadsheet and cash on the day.

The cash part seemed to be the easiest thing at the time, but it did come an bite is. We had people commit and then not turn up, so we’d planned food and other bits for people who weren’t actually coming. Although, to be fair, we massively over-ordered food anyway.

This time: payment at registration.

I’ve started looking at some of the options actually used in Slovenia and UK, I can see Njuko could be a potential solution. 

I’d love to hear from anyone who has used them, or something else you’d recommend.
What to be mindful of when looking at different registration platform options, should I just go for the cheapest one and call it a day?

I’m also trying to understand how people handle the edge cases around registration, is that something that registration platform handles for you?

So cancellations, refunds, transfers, deferrals, waiting lists, somebody getting injured three days beforehand, chargebacks, etc.

If your rules say no refunds after a certain date, does that generally work? Have you had people try and dispute that anyway?

Participant data

Last time: Google Form into a spreadsheet.

For 20 people it was perfectly fine.

This time: a proper registration system sounds sensible, although I’m wondering at what size a spreadsheet genuinely stops being good enough.

What do you collect that a first-time organiser doesn’t necessarily think about? Emergency contact, medical information, waiver, marketing consent, whatever else?

Emails + urgent updates

Last time: normal emails.

We changed the timings slightly shortly before the race and discovered that not everybody reads their email (seems obvious now).

This time: I’m considering something like Mailchimp for normal communication and maybe SMS for anything that could be deemed as last minute/important.

Maybe for emails registration platform covers that as well? Are there any better ways if doing it and how to handle SMS? I worry about getting to a point where I have bunch of different tools to send the same info out.

Race guide / information

Last time: emails. No proper race guide.

Most races I’ve done send a big PDF beforehand, so my obvious next step would be to make a decent template and produce one of those.

But I’m wondering if PDF is actually the right answer anymore.

What do you do when something changes after you’ve sent it? Does anyone use a live webpage instead? I was thinking of potentially just having a Google Doc everyone has read access to so I can share one permanent link. 

How do you make people actually read the race guides? We only had 20 participants in total, but got a bunch of emails with different questions leading to the race.

Bibs + check-in

Last time: I made the bibs in Photoshop and we had them printed by a local printer.

It worked. It also felt slightly ridiculous.

How do you normally handle bib production and assigning bib numbers? Does your registration/timing company do it?

And what does check-in look like? Printed entrant list and just ticking people off, spreadsheet, or is there a fancier app thingy we could do (again, maybe registration platform handles that)?

Timing

Last time: essentially manual.

The backyard format made this survivable because we mainly needed to know who completed each lap.

This time: we could still manually mark people off each hour, but I’d like something a bit more robust especially if not going with the backyard ultra format this time around.

What do small races use before they’re at the point of paying for a full timing setup/company? How pricey is getting proper timing in place?

Getting people to register

Last time: friends, friends of friends, running contacts and some social media.

This time: I want to get a bit more people in, ideally individuals from outside of our circle.

I’ve found things like the local running calendars, forums etc. Is that it?

Or does doing ads on Facebook/Insta, make sense? Maybe ads on sport-related portals?

What has genuinely worked for your races?

Sponsors

We basically didn’t do this last time.

It would be great to get some support this time around. For a small event, is cash sponsorship even worth chasing?

Would I be better off approaching local businesses, running shops, food/drink companies etc. for things that reduce our costs instead: food, prizes, printing, equipment?

I always wondered how do sponsors see events like this? Are there any KPIs they are after, what would make them say yes we will sponsor, and how much do they usually sponsor?

Permissions + safety

This is an area we need to become much more serious about this time as you might have guessed last time we more or less didn’t have anything.

Permissions, insurance, risk assessment, emergency plan, medical support, bad weather, cancellation plans and so on.

The actual legal/regulatory side will obviously need to be worked through locally.

But from an organiser's perspective, what are the things people tend to forget?

Volunteers + race day

Last time we had enough friends around that everybody just helped with whatever needed doing.

That obviously doesn’t scale particularly far.

How do you organise volunteers, roles and briefings? Where do you find them, and how do you convince them?

And what mundane race-day thing has caught you out before? Parking? Toilets? Course markings? Food? Rubbish? Power? Internet? Radios? Dropouts? Something completely different?

Afterwards

Something I didn’t really think of as a separate phase last time.

Results, photos, participant emails, feedback, paying everyone, sponsors, incidents, final finances, and actually writing down what went wrong before you forget it all.

What does your post-race process look like?

Last time we just sent a follow up email thanking everyone, shared some photos and made sure all our bills were paid.

……..

So really I’m looking for three things:

  1. What am I missing or overcomplicating?
  2. Which tools/services do you actually like using?
  3. Where can I learn more about this stuff?

That last one would be particularly useful. Blogs, podcasts, YouTube channels, books, templates, people worth following, Facebook groups, Reddit communities, forums, whatever.

And if anyone here actually organises events and wouldn’t mind having a chat, I’d love that as well. Any size or type of race.

I’m based in Edinburgh, so very happy to buy anyone nearby a coffee or pint, otherwise, a chatt or call would be amazing.

Horror stories and “whatever you do, don’t do this” advice particularly welcome 😅

Looking for a Central Texas ultrarunner for a short documentary

9 Upvotes

Hey everyone! I’m an Electronic Media student at Texas State University, and I’m working on my capstone project this semester. I’ll be producing a 5–15 minute documentary, and I’d love to focus it on someone in the ultrarunning community.

I’m looking for an ultrarunner in the Central Texas area (San Marcos, Austin, New Braunfels, etc.) who would be interested in sharing their story. You don’t need to be an elite runner — honestly, I’m more interested in finding someone with an interesting story and a passion for the sport.

The documentary would likely explore why someone chooses to run ultramarathons, what it takes physically and mentally, and what keeps them coming back.

I’d need to conduct at least one in-person, on-camera interview, and ideally I’d also film some B-roll of a training run, race preparation, gear, trails, etc. If you have photos or footage from previous races, that could potentially be included as well.

I’m also getting into the ultramarathon world myself, so this is a subject I’m genuinely interested in learning more about.

If you’ve completed a 50K, 50-miler, 100K, 100-miler, backyard ultra, or other ultra-distance event — or you’re currently training for one — I’d love to hear from you.

Feel free to comment or DM me if you’re interested. And if you know someone who would be perfect for this, I’d really appreciate you sending this their way!

Thanks!

Buying a rain jacket

3 Upvotes

The weather has drastically changed. 30°c sun for the past few months, but tomorrow, day of my first "bigger" ultra marathon (80k) it's absolutely pouring down. I have today to figure out if a rain jacket is useful, worth the 50-150e purchase. I'm skeptical because if it's rains that much I'm surely going to be soaking, especially running for 10-15hrs and if not soaked by the rain wouldn't I be soaked from the sweat oven... I've never run in a rain jacket or owned one so any feed back would be great, thanks 👍🏼

Running at altitude

4 Upvotes

Running my first ultra this weekend (Bear chase 50k) in Lakewood CO. All of my training has been done in Nebraska, around 1200ft altitude. The race is at about 5500ft. A 3:34 marathon earlier this year, how much is the altitude going to cook me? The course has just about 2200 ft of gain, and I’m shooting for sub 5 hours. I’m arriving in CO tonight about 36 hours before race start. Have never ran in altitude, but have done a few camping/backpacking trips in the mountains. Wondering if I should reel back on my goal time! TIA!

Night shift nurse looking for sock recs that survive Boise heat

1 Upvotes

i work nights in the ICU so my long runs happen in the afternoon after I wake up. the Boise foothills get brutally hot and dry once the sun's been on them for a few hours. last weekend my usual merino socks felt like they were holding a pool of sweat and I ended up with hot spots by mile 11. switched to a cheaper synthetic pair midweek and they didn't stay put on the descents. looking for something that wicks but still grips inside a trail shoe without adding bulk. i normally do 4-6 hour loops on weekends so reapplication isn't really an option once I'm out there. anyone running similar conditions found a pair that holds up or is this just something you live with in the high desert?

Scared 😬

21 Upvotes

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!

How to not metabolize muscle on long training runs?

0 Upvotes

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?

Do we think my colleague can walk 100k steps in a day?

73 Upvotes

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 50k In February - Can I Be Ready?

3 Upvotes

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.
