FAQ: All About Swim Events

What types of swim events use RunSignup?

Open water swims, USMS-sanctioned competitions, charity swims, aquathons, and multi-event swim series all run on RunSignup. Many use the same platform for registration, fundraising, and race day.

How do companies pay for their employees’ race registrations?

You choose how teams pay. Companies can buy a pre-paid package that covers a block of entries, or pay as employees register. RunSignup can invoice teams automatically after team joining closes. Invoices can be paid by credit card or check, before or after the event. Captains can view their team’s invoices and payments from their RunSignup profile.

How does RunSignup validate US Masters Swimming memberships?

RunSignup checks USMS memberships in real time during registration. Swimmers without a current membership can buy one without leaving checkout, and the USMS waiver is collected alongside yours.

Can I offer different distances and wetsuit divisions for one swim?

Yes. Set up as many distances and divisions as you need in one event. Check-in presets also let volunteers verify or change a swimmer’s wetsuit category on site.

How can RunSignup help keep open water swimmers safe?

Custom questions collect emergency contacts and qualifying-swim proof at registration. On race day, certified timers can turn on RaceJoy for chip-timed alerts and on-course monitoring.

Can I run a lottery registration for my open water swim?

Yes. The lottery tool collects entries and payment details up front, then charges only the swimmers you select, which works well for capped events.

How do charity swims collect donations through RunSignup?

Swimmers can donate at checkout, and you can add individual and team fundraising pages, fundraising minimums, and support for one or multiple charities.
