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

Why UltraSignup?

Most registration platforms are built for any event — 5Ks, corporate fun runs, charity walks. UltraSignup is built for endurance.

Your participants are already here. They use UltraSignup to track their race history, find their next adventure, and follow results. When you list on UltraSignup, you're not hoping the right people stumble across it — you're putting your event in front of a community that's actively looking for exactly this.

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
• Running the Alps — guided running expeditions across Europe's biggest mountains

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

If someone has to train for it, sign a waiver, or talk themselves into it — it fits.

What you get

• 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

Results are optional. But when you publish them, your event becomes part of a permanent record that runners browse, share, and return to. That's a discovery engine most platforms can't offer.

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 in-person start. Participants submit results after. Virtual challenge, self-reported mileage month.

Club or group — ongoing membership-style signups not tied to a single date. Running club dues, season passes, team registration.

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, donations.

Do I need to publish results? No. But when you do, your event builds a history on the platform that runners find and follow year after year.
