Trail races and ultrarunning continue to grow in popularity, and race organizers need technology that can keep up. RunSignup continues to lead the way as a technology-based registration platform, supporting a growing number of trail and ultras with powerful tools for registration, race-day operations, and participant management.
This blog reviews some of the top reasons trail races and ultras continue to move to RunSignup, along with several customer examples.
Some of Our Favorite Features
Free Website: Races get more than a simple page, they get a full website. Easily create and match your branding for your race website, with unlimited pages and system data like countdown clocks, participant and team lists, results, photos, and more ur own content.
Free Email: Upload any number of contacts and send any number of emails — for free. Emails are branded for your race and tailored for your needs with custom list uploads, smart data replacement tags, and beautiful designs.
RaceDay CheckIn App: Streamline your race day and eliminate lines with the RaceDay CheckIn App. Whether you’re assigning bibs dynamically on race morning, managing add-on pickups, or checking in teams, the RaceDay CheckIn App can help.
Multiple Waivers: Support multiple waivers to make paperwork easy when you, your venue, and/or your sponsor all need different waivers.
Participant Insurance: Boost revenue and reduce admin work with optional participant insurance during registration—Protecht RegShield handles all insurance management and refunds.
Participant Management: Reduce customer service headaches with self-serve tools for transfers, bib exchanges, and (optional) refunds—plus waitlists, registration caps, fees, and bulk actions for easy updates at scale.
Volunteer Management: Manage volunteers right from your race dashboard—create roles and shifts (with coordinators), set min/max capacity, collect waivers and custom info, email targeted lists by role, and reward volunteers with vouchers for future events.
