For coaches & testing studios

Coach a team. Without spreadsheets.

Your athletes connect Strava or Garmin once and their training arrives on its own. You read it — load, form, laps, the same session against every previous attempt — build next week, and it lands on their watch. All of it anchored to zones from a real lactate test instead of a percentage of a guess.

Only test people? If you run step tests for clients and hand back a report — no calendars, no athletes to follow — that is its own product.

The workflow

From their watch to yours and back

The loop a coach actually runs, per athlete, without a spreadsheet in the middle of it.

1

Add them

Invite an athlete or create them yourself. They connect Strava, Garmin or Apple Health once and every ride, run and swim lands in your workspace from then on.

2

Set the zones

From a lactate test rather than a percentage of an estimate — yours, or one a studio ran. Every number downstream is anchored to those two thresholds.

3

Build the week

Structured sessions with targets in watts, pace, heart rate or their own zones, dropped straight onto the athlete’s calendar.

4

It reaches the watch

The session is written into their Garmin Connect calendar as a structured workout — the steps become laps, with targets, on the device.

5

Read what happened

Planned against completed, load and form, laps and intervals, and the same session compared with every previous attempt at it.

Your brand, not ours

A report that sells your service

Every test exports as a clean PDF carrying your logo, studio name and contact details — the professional handout clients expect, with LT1, LT2, OBLA and their full power / heart-rate / pace zones.

Everything in the Coach workspace

Built for a roster, not one athlete

The tools that turn testing into a coaching service.

One workspace, every athlete

Switch between athletes in a tap. Status dots show at a glance who is training, who has gone quiet and who is due to be retested.

Their data arrives on its own

Strava, Garmin and Apple Health sync in the background — power, pace, heart rate, cadence, laps and per-second streams. Nothing to upload, nothing to chase.

Load, form and fitness

TSS per session, CTL, ATL and TSB per athlete, with a plain-English read on whether they are fresh, productive or digging a hole.

The same session, every time they did it

Repeat workouts are recognised and grouped, so 5×8min in August sits beside the same session in March — power, heart rate and what moved between them.

Structured workouts onto their watch

Build the session once and it appears in their Garmin Connect calendar with every step and target intact. They press start; you see it come back.

Planned versus completed

Duration, distance, load and average power side by side with what you asked for — per session and across the week.

Zones out of a real test

LT1 and LT2 by six methods with the measured points on top, and power, pace and heart-rate zones generated from them.

The season, not just the week

An annual structure with blocks and target load, races with a countdown and taper, and a weekly review you write once and keep.

Talk about the session itself

Comments live on the training, not in a separate thread — the athlete asks about Tuesday under Tuesday.

“I coach 14 triathletes. The athlete switcher and the ‘ready for lactate’ filter saved me two hours a week. Status dots are pure gold.”
