Time slots give athletes the ability to choose their preferred competition window at the time of registration. Instead of arriving on event day to figure out when everyone competes, you arrive with a pre-distributed schedule that athletes have already opted into.

This is particularly valuable for mass participation events — such as obstacle course races, endurance challenges, or large-scale fitness competitions — where spreading athletes across the day is essential to keeping the event running smoothly. It's also a great option for any organizer who simply wants to give their athletes the flexibility to plan their day, compete alongside their friends, and feel more in control of their experience from the moment they register.

Reduce no-shows
When athletes actively choose a time slot they're committed to, they're more invested in showing up. An athlete who has picked their preferred window — especially one shared with training partners or friends — is far less likely to drop out or miss their heat.

Give athletes flexibility
Time slots let athletes plan around their day. Whether they need to be done by noon, want to compete alongside a training partner, or prefer a quieter afternoon slot, giving them that choice creates a better athlete experience before competition day even begins.

Control your event flow
Set capacity limits per slot so no single window becomes overloaded. Once a slot reaches capacity it closes automatically, naturally distributing athletes across your event day without any manual intervention.

Plan with real data
By the time registration closes, you already know exactly how many athletes are competing in each window — across all divisions. That means smarter staffing, more accurate setup, and a well-paced event day you can plan with confidence.

1. Create your time slots
Navigate to Event Setup > Timeslots and create your slot groups. For each group you'll set a start time, a capacity limit, and the divisions the group applies to. The divisions you attach determine how the capacity is shared — see Capacity and format flexibility below. You can create as many slots as your event needs across one or multiple days.

2. Athletes choose at registration
During the registration flow, athletes are presented with your available time slots and select the one that works best for them. Slot availability is shown in real time so athletes can see how many spots remain in each window.

3. Slots fill automatically
Once a slot reaches its capacity limit it closes and is no longer selectable. Athletes are naturally guided toward other available windows without any manual management on your end.

4. Review your distribution
As registrations come in you can monitor how athletes are distributing across your slots from the event dashboard. If you need to adjust capacity or add new slots as your event grows, you can do so at any time before registration closes.

Time slot capacity is controlled by which divisions you attach to a slot group — not by a separate format setting. This gives you flexibility in how individual and team divisions share (or don't share) the same competition window.

The shared pool option is especially useful when you don't need to separate formats at the same start time. For example, a 9 a.m. slot with a capacity of 100 attached to both individual and team divisions can fill as six individuals and ten teams, five and five, two and eight — any combination that fits the pool. Instead of building two separate 9 a.m. slots and guessing how to split capacity between individuals and teams, you set one slot and let registration shape the mix. Each team counts as a single registration against the cap, so a four-person team occupies one spot, not four.
