Stop guessing your training.
Taper reads your physiology, models fatigue across multiple body systems, and tells you exactly what to do — every day. Not a plan. A decision engine.
Every session hits different
Taper tracks muscle load, impact, cardiovascular fatigue, and neuromuscular stress — each weighted by the session. A long run doesn’t stress your body the same way as intervals, strength work, or other sports. Most systems treat it as one load. Taper measures what each session actually does to your body — and where.
Your plan fits your life.
Not the other way around.
Pool on Tuesdays only, gym access limited, travelling on Wednesday — Taper works around your real life, not an idealised version of it.
Friday run club, Tuesday masters swim, Sunday bunch ride. Your commitments are locked. Taper builds the rest of the week around them.

Your body changes daily. Your plan adapts with it.
Every morning, Taper reads your physiology — HRV, resting heart rate, sleep, temperature, and respiratory rate — and turns it into a readiness signal, applied directly to your fatigue model.
A bad night doesn’t just lower readiness — it changes what your body can absorb today. A strong recovery trend unlocks progression. Your plan shifts with you, not against you.
Not a chatbot.
A decision layer.
Taper tells you what to do, why it made that call — and negotiates when life gets in the way.
When reality changes,
your plan changes with it.
Taper reads every signal, every morning — and responds before you have to think about it.
Taper adapts automatically.
You still steer it.
The engine works on its own. But serious athletes have instincts that no model fully captures. Taper lets you shape the direction — and handles the execution.
Periodized from day one. Recalculated every week.
Tell Taper your goal event and target date. It builds a full periodized plan — then adjusts it every week based on your actual training response, not assumptions.
Aerobic foundation. Lower intensity, higher volume. Building the engine.
Race-specific intensity. Threshold, tempo, long bricks. Raising the ceiling.
Maximum training stress. Race-pace work, tune-up events. Sharpening the edge.
Volume reduces. Intensity maintained. Arrive fresh, sharp, ready to perform.
One body. Multiple goals. One system.
Taper holds all your disciplines and goals in one model. Strength work affects your run schedule. Race proximity affects your gym sessions. And when the week gets tight, it protects the minimum viable work that keeps every goal moving.
Tempo first, squats tomorrow. Your CNS needs 24h between max-effort running and heavy lower body loading. Stacking them costs you both sessions.
Your run plan doesn't know about yesterday's ride. Long ride loaded your legs at 68%. Intervals moved to Thursday — protecting the quality session, not discarding it.
Marathon build weeks → strength drops to maintenance. Deload weeks → lift heavier. Your goals aren't competing. They need sequencing.
Plans the lift. Plans the long run. Protects the week when life gets messy.
Taper can prescribe strength and endurance in the same system, then rebalance the week around multiple goals instead of dropping sessions blindly.
Intervals, long rides, circuits, sets, reps, and rest all live in the same system. Taper can prescribe the run and the lift, then sequence them so they stop sabotaging each other.
Travel week detected. Keep one run quality, one maintenance lift, and one short swim touch.
When life compresses the week, Taper doesn’t just delete sessions. It protects the minimum dose that keeps each goal alive, then tells you what can flex.
THE DIFFERENCE
Most apps track training.
Taper makes training decisions.
- Reduces all fatigue to a single TSS number
- Follows a static plan regardless of how you feel
- Doesn't know if your legs are fresh but cardio is cooked
- Breaks down when you miss a session
- Has no concept of multi-sport load interference
- Can't explain why it gave you any particular session
- ✓ Models fatigue across 4 independent body systems
- ✓ Adapts every session to your actual state that morning
- ✓ Knows exactly which systems are loaded and which are fresh
- ✓ Rebuilds your week automatically when plans change
- ✓ Tracks load independently per sport — built for multi-discipline
- ✓ Explains every decision and negotiates when you push back
Stop guessing. Start knowing.
Taper is in private beta with a small group of serious endurance athletes. Join the list to get early access.
Legs and cardio are loaded from the run. Upper and neuro are untouched. You’ll be recovered in time for Tuesday’s interval session.
