Each race is scored against the ideal split shape for that event, and the pacing pattern is named — even leg-by-leg on relays.

Roster rankings, cut tracking, race comparison, team trends, and an assistant that knows your data — all updated instantly.
Pacing intelligence
It reads the race the way a coach would.
Every swim is compared to its ideal split distribution and labeled with a plain-English pattern — even pacing, fading home, went out too fast, negative split, and more. Color-coded so you spot what to fix at a glance, with an estimate of the time left on the table.

Race comparison
Put any two swims side by side.
Compare a swimmer across meets, or against a teammate — even across distances. Splits line up and the fastest at each point turns green, so improvement (or a rough back-half) jumps right out.

SwimBase Assistant
Ask your data anything.
A chat assistant grounded in your team's real results — on every page. Ask who to put on a relay, where a swimmer can find time, or how the team's trending. It links straight to the swimmer and meet pages, and never makes numbers up.
