Taper is a calm marathon training plan and running coach for people who would rather run than read charts. Every morning it answers one question – what should I run today, and why? – and quietly handles the rest.
PEAK WITHOUT BREAKING
• A training plan built back from your real race date: 5K, 10K, half marathon or marathon.
• It bends around your life. Miss a run, sleep badly or feel a niggle, and the plan reshapes itself instead of piling on.
• Built-in guardrails stop your weekly distance and long runs from ramping up too fast, the usual road to injury.
• Runs from Apple Health tick themselves off. Nothing to log by hand.
TRAIN YOUR GUT TOO
• Plenty of marathons fall apart around mile 18 because the stomach was never trained. Taper treats fueling as training: you practice on long runs for months, so race day holds no surprises.
• A race-day fueling plan in plain words: when to take a gel, when to drink, how much salt, and when caffeine helps.
• Race-week carb loading, worked out for your body weight.
A COACH THAT ADAPTS TO YOU
• Morning readiness from your overnight heart-rate data: a gentle "go for it" or "take it easy today".
• Your coach reads your runs and explains what they mean in plain words. It runs on your device, so your data stays with you.
• Run form check: film twenty seconds of running with your iPhone propped up, and see your cadence, symmetry and form explained simply. Videos never leave your phone.
WATCH EVERY RUN ADD UP
• Weekly distance, personal bests and streaks at a glance.
• Share a clean run card with your club or friends.
