Training science, product notes & our story
Notes from the team building Boost — what we're learning about swimming performance, readiness, and where the product is headed.

Race analysis, after its first gala
Race mode went to its first gala on 10 October. 49 of 51 events captured, a PB the card doubted, two relays we got wrong, and the one thing a coach from another club asked.

Race analysis, before its first gala
Race mode goes to its first gala on 10 October. Before it does: what it measures off each wall, and the talking point we had to scrap.

Two Weeks In
Fourteen days into the 2026-27 season. Nine meets mapped, step test data feeding live training zones, and the daily brief already earning its keep.

Your Swim Is Lying to Your Training Load
Triathlon's single load number is built from one trustworthy input, one rough one, and a swim metric that actively misleads. Here's why the swim inflates your load — and what to watch instead.

Nine Tests, Three Questions
We run nine tests, but they aren't nine separate answers — they're three questions about one athlete: is the engine adapting, is the chassis efficient, is the nervous system ready? The value is in reading them together.

The Cold Is Training Too
Distance and pace don't capture what open-water swimming costs an athlete. The cold, the chop, the current and the rewarming are all training load — and they're the part nobody's measuring.

The Tired Swimmer Isn't Tired From Swimming
The fatigue that wrecks a session often didn't come from the pool. Your swimmers carry exams, jobs and broken sleep into the water — and the training load alone can't see any of it.

What the Data Won't Tell You (And What It Will)
We sell a platform built on monitoring data — so here's the honest version of what it can and can't do. The numbers don't hand you the decision. Used well, they stop you being blind.

Coaching Is Breaking Its Coaches
UK swim coaches are roughly fourteen times more likely to be struggling with depression and anxiety than the swimmers they train. A look at why — and the one part of it software can actually lift.

You Cannot See What Your Swimmers Feel
Coaches and athletes agree on the hard sessions — and disagree about the easy ones. That gap is where recovery quietly stops being recovery, and the research has a lot to say about it.

The Swimmer We Got Wrong
Every coach knows the Tuesday night with too many tabs open, guessing whether the set is right for the swimmer in front of them. This is the story of the swimmer we kept getting wrong — and the tool we built to stop.
