SwimSet

Warm-up, main set, cool-down — type in the reps and it keeps the running total, works out your send-offs against the clock, and prints a sheet you can read on the pool deck. No login, no plan to follow. You write it, you swim it.

A pace clock. It’s here because every pool has one.

The builder

Type your sets the way you'd write them on the board — 8 × 100 free on 1:40. The slip on the right keeps the running total.

Starters

Five sessions to begin from. Tap one and it drops into the builder — then change whatever you like.

Send-offs

Give it a recent time and it suggests a send-off for each effort, and marks where to leave on the clock.

Leave on the

Send-offs round up to a tidy interval and aim for ~5–15s rest. Tap a row to set the clock.

If you've never written a set

Most go warm-up, a short sharpener, the main set, then a cool-down. That's the whole shape — the rest is detail.

01
Warm-up

Wake up

Easy swimming, a little kick and some drills to find your stroke. Usually 15–25% of the session, all low zones.

02
Pre-set

Build speed

Short, sharp efforts — builds, descends or technique work — to bridge the gap before the main set. Optional, but it sharpens you.

03
Main set

The point

The reason you got in: endurance, threshold or sprint work. Where the send-offs matter and most of the distance sits.

04
Cool-down

Bring it down

Easy, loose swimming to flush the legs and arms. A few hundred metres of recovery to finish — never skip it.

How hard, in plain terms

Reading a set

8 × 100 — eight reps of 100m on 1:40 — leave every 1:40 build — get faster across the rep descend 1–4 — each rep faster negative split — 2nd half faster IM — fly, back, breast, free pull — arms only, with a buoy kick — legs only, on a board
