# How to Set Up Registration for a Duathlon, Aquathlon or Multisport Event

Multisport events are a gentle way into endurance racing. A duathlon combines running and cycling, an aquathlon combines swimming and running, and relays let a team share the work. They attract first-timers, so clarity matters more than anywhere else. If entrants cannot tell the formats apart, or do not know how a relay works, you will answer the same questions for weeks. Here is how to set registration up so they do not need to ask.

## Name your formats clearly

A duathlon is usually run, then bike, then run. An aquathlon is swim then run. An aquabike is swim then bike. Each organizer sets its own distances, so write them out for every format and show the order of the disciplines. Treat each format as its own category with its own price, capacity and start time, and show distances in km or miles the way each athlete prefers.

## Separate individuals from relays

Relay entries behave differently from individual ones. A team of two or three registers together, pays once and may share a single bib or take one each. Offer relays as their own category with their own price, and let the team captain register the whole team in one booking and invite each member with a personal link. Set the largest team size on that ticket so it matches your format.

## Keep capacity realistic

If your event has a swim, capacity per wave matters for safety, as it does in a triathlon. If it does not, transition space and course width decide. Either way, set a limit per start time or wave, give each its own ticket, and add a waitlist for any that sell out.

## Ask about bikes and kit

A few simple questions help on the day: bike type, club or team name, and T-shirt size. Add tick-boxes confirming your helmet rule, your bike check-in time and your transition rules, so every entrant has accepted them before paying.

## Waivers and safety

Use a clear, versioned waiver, and keep the signed name, the time and the exact wording attached to each entry. Collect an emergency contact and blood group, and make sure your safety team can open a single list of them. For relay teams, remember that each member needs their own details, not just the captain.

## Check-in

Assign a bib per person, check each person in individually, and keep a manual entry option for anyone who registered offline. A clean registration list you can search and export keeps the queue moving.

## Common mistakes

- **Format names that mean different things to different people.** Spell out the order and distances of each discipline.
- **Relay teams registered under one name.** You need every member’s details and waiver.
- **No limit per start.** Capacity should follow your safety cover and course width.
- **Rules only on a web page.** Put helmet, check-in and transition rules into the form.

## Set it up on endurace.pro

- Several formats per event, individual and relay, each with its own price, capacity and distances in km or miles.
- Group booking for relay teams with one payment, a personal link for each member, and a largest team size set by you.
- A separate ticket per start time, each with its own capacity and a waitlist when it sells out.
- Your own questions per category, including choose-one for bike type and tick-boxes for rules.
- Waivers stored per registration, plus date of birth, T-shirt size, blood group and emergency contact in a CSV you can export.
- Bib assignment and check-in per person, including each member of a group booking.
