Host any endurance event on UltraSignup: trail runs, ultras, virtual races, Antarctic expeditions & more. Where athletes go to find their next adventure.

Why UltraSignup?

Most registration platforms are tools. UltraSignup is something endurance athletes actually come back to. 

They track their history here. They find their next race here. They come back after the race to see where they finished and who else was out there. 

When you list on UltraSignup, you're not placing an ad. You're showing up where athletes are already looking.

If it's hard, it belongs here

UltraSignup started in trail running. But the community it's built around, people who sign up for hard things, shows up for a lot more than that.

On the platform right now:

• Prairie Goat VK — a vertical kilometer in Manitoba
• Heart of the South — a 350-mile mystery road race where runners don't find out the start location until they board the bus
• Last Paddler Standing — an endurance SUP race on a Florida lake that goes until one person is left standing
• WILD Marathon — marathons in Peru, Tanzania, Turkey, and beyond
• FCT x The Iceberg — a 50K on the Antarctic Peninsula, aboard a ship, polar plunge included
• Run the Alps — guided running expeditions across Europe's biggest mountains
• SHEastern States Weekend — a women's running camp on the Eastern States 100 course in the PA Wilds, lodging included 
• Spring Training Camp — a coached skills weekend in the Catskills, designed for runners who want to get better in the mountains

Plus running camps, retreats, trail ultras, road marathons, gravel bike races, triathlons, running clubs, beer miles, and everything in between.

If you had to train for it, talk yourself into it, or sign something before the start, it belongs here.

Here's what comes with every UltraSignup listing:

• A public event page, visible to the UltraSignup community
• Online registration and payment collection
• Custom questions - collect exactly what you need
• Capacity limits and waitlists
• Discount and coupon codes
• Automated and manual email tools
• Participant management and reporting
• Optional add-ons (shirts, meals, donations, parking, and more)
• Results publishing - connects your event to athlete profiles and race history

Publishing results is optional. But when you do, your event builds a history. Runners find it, share it, come back to it year after year. Most platforms can't say that.

Pick your setup

Single event: one day or one weekend, any number of distances or waves. Covers most races.

Series or program:   recurring dates. Weekly trail class, 6-week training series, monthly workshop.

Virtual / self-reported: no physical start line. Runners log their own results. Good for virtual challenges or mileage-based events.

Club or group: for ongoing memberships not tied to a single race date. Running club dues, season passes, team signups.

Online event: registration and communications for a webinar, coaching session, or remote event.

Setting it up

Click Host an Event and move through five steps:

1. Location — country, state/province, or mark it virtual
2. Event basics — name, city, zip, timezone, website (optional)
3. Date, waiver, and capacity — paste your waiver, pick your date, set a cap (no hard limit? use 10,000)
4. Registration option type — most events use Race Registration; clubs use Membership; camps use Retreats
5. Event type — single event, program, multi-event, or ticket sales

Setting up a multi-day event or club program? Contact Member Ops before you start — those setups have a few extra steps and it's faster with a hand.

Common questions

We're not a traditional race. Does UltraSignup work for us? A paddleboard race that lasts three days and a 50K in Antarctica both found a home here. If you're not sure, reach out.

Can I collect custom info during registration? Yes, add any questions you need.

Can I sell add-ons or accept donations? Yes. Shirts, meals, parking, gear, donations, whatever makes sense for your event.

Do I need to publish results? Do I need to publish results? Nope. But events that publish results get found. Runners search by course, by year, by friends. Results put your event on that map.
