Swim, ride, run — one coach, one plan, built around how recovered you are today.

Every day

Open the app, know what to do

No spreadsheets, no guesswork. CoachSage reads your recent training and recovery and tells you exactly what today's session should be — and why.

Miss a day? It adapts the rest of your week instead of nagging.

The USP

One integrated multi-sport week

Triathlete, or just mixing it up? CoachSage blends running, cycling and swimming into a single balanced week — not three plans fighting for your time. Injured and can't run? It keeps you fit on the bike and in the pool.

Each day is tagged with its sport and the right target — pace, power or pace-per-100m — right down to a brick session.

An integrated triathlon week: easy run, endurance ride, threshold swim, threshold run, a brick session and a long run
Goal-driven

A real plan to your race day

Set your event and date. CoachSage builds a periodised plan — base, build, peak and a proper taper — from today to the start line, and reshapes it every week around how your training is actually going.

Watch the whole block, phase by phase — base, build, peak and taper.

Recovery-aware

Your week, session by session

Every day laid out with the session, distance and target — and adjusted to how recovered you are, read from your overnight HRV, resting heart rate and sleep. Hard days land when you're ready for them, judged against your own baseline.

Each session comes with the why, not just the what.

Share the journey

Tell your friends

Cross the finish line and share the moment — or your full race-day plan — as a beautiful card. One tap, and it's ready for Messages, Instagram or wherever your crew hangs out.

Your finish, your race plan, your season recap — all shareable.

Swim deeper

Laps, strokes & SWOLF

Swim workouts now show per-length lap count, total strokes and an average SWOLF score from your Apple Watch data — so you can track efficiency, not just distance.

One more reason the pool sessions feel purposeful.

Race day

Your plan on the Lock Screen

On race morning, your checklist and next cue sit on your Lock Screen and in the Dynamic Island — so you can glance at pacing, fueling and transitions without unlocking your phone.

One tap from the race plan, and it stays visible until you cross the line.

In your pocket

A coach that remembers

Ask anything — "can I move my long run?", "what do I do about the sessions I missed?" — and get answers that know your plan, your history and how you've been feeling. Pick a coaching style, from encouraging to strict.

It remembers the conversation, so follow-ups make sense.

Your data stays yours

CoachSage reads your training from Apple Health and shows you exactly what it read — every sleep session and workout, and the app each came from. Your health metrics are used to coach you and never stored on our servers.

Sign in with Apple; your goals and plans follow you to a new phone.

“I built CoachSage as a runner and former triathlete — I couldn’t find a coaching app that brought it all together, with tailor-made plans that actually adjust to your progress.”
