Taper Join the waitlist

BuiltBackwardsFrom race day

Taper drafts your season from the race morning back to today, out of your own training history, and redraws it when a week goes sideways.

Private beta. Free to join; invites go out by email.

Your history comes in from Strava, TrainingPeaks, and FIT, TCX or GPX files from your watch.
Taper morning check-in: How did you wake up? with Rough, OK and Good.
Taper progress card: your fitness holds steady through race day; freshness now Working, race morning Fresh.
Taper marked done sheet for a 3 by 8 minute tempo session: 62 minutes, about 12 km planned.
Taper rest day: nothing planned, rest is part of the plan, next up a 3 by 8 minute tempo session on Tuesday.

A plan that starts at the finish line and works back to today.

Name the race and the date. Taper reads every session you've logged, finds the fitness you actually have, and drafts each week between now and the start line.

Each morning opens on one session: what to do, how hard, and why it's there. When a week goes sideways, the weeks that are left are redrawn. The race date and the taper never move.

How a season is built

How a season gets built.

Four steps, in the order a coach would take them. You only do the first one; Taper keeps the rest current every day until the race.

  1. 001

    Start at the finish.

    Pick the race, the date and a goal time if you have one. Every week is planned back from that morning.

  2. 002

    Your training, not a template.

    Bring Strava, TrainingPeaks or your watch files. Taper finds the load you've actually handled and builds from there, three harder weeks to every easier one.

  3. 003

    One session, explained.

    Today's session with its paces and why it's there. One tap on how you woke up can reorder the week; the total load stays the same.

  4. 004

    A taper that holds.

    The final weeks follow a fixed taper protocol that nothing else can override, and race morning comes with pacing for each third.

When a week goes sideways, the season moves with it.

Ill for five days? When a week closes well off plan, every week that's left is redrawn from where your fitness actually is.

Four screens. The whole season.

Straight from the app: a sample athlete's 16-week half-marathon plan. Yours is drawn from your own history.

Today62 min · ≈12 km

Taper Today screen: Tempo day, a Working readiness chip, the week strip, and today's 3 by 8 minute tempo session at 1 hour 2 minutes with its pace and a Mark done button.

One session, fully explained.

What to do, how hard, how long, and why it's in the plan. One tap when it's done.

Session3 × 8 min tempo

Taper session screen: 1 hour 2 minutes, about 12 km, the effort profile, and block cards with pace ranges, the main set grouped as a repeat of three.

Every block has a pace.

Warm-up, the main set as one repeat, cool-down. Each with its effort and its pace window.

Season1:49 reachable · 1:45 goal

Taper plan screen for the Toronto Waterfront Half: a reachable 1:49 against a 1:45 goal, the season as one phase-coloured bar, and week rows.

A straight answer on your goal.

A reachable finish from your own fitness, next to the goal you set. When it isn't there yet, it says so.

Race morning5:16 · 5:10 · 5:04

Taper race morning screen: target finish 1:49, negative-split pacing of 5:16, 5:10 and 5:04 per kilometre for each third, gels at 15, 50 and 85 minutes, and a heat note.

Race morning, already decided.

Pacing for each third, when to take a gel, and what to do if it's hot.

Sixteen weeksfrom onemorning

Taper adjusts like a coach. Some things are rules, not settings: weekly increases are capped, deep fatigue forces a recovery week, and the taper is fixed.

Here is what those rules produced for one sample half marathon.

  • Minutes at tempo on Tuesday24
  • Reachable finish, goal 1:451:49

Questions, answered.

Who is Taper for?

Runners training for anything from a 5K to a marathon, and triathletes. It's built for people who train on their own and want a plan that adjusts the way a coach would.

What do I need?

A phone. Taper is a phone app with a web dashboard. Your history comes in from Strava, TrainingPeaks, or FIT, TCX and GPX files exported from your watch.

What will it cost?

Pricing will be announced before the public launch. Joining the waitlist is free and doesn't commit you to anything.

When do I get in?

Invites go out by email in waves as beta places open. People on the waitlist hear first.

What if something hurts?

Log it on the phone. Only that tissue's load is capped, and the volume you lose is offered back on the bike or in the pool. A healthy runner is never capped just in case.

Will it push me too hard?

It can't. Week-to-week increases are capped, deep fatigue forces a recovery week, and the final weeks before a race follow a fixed taper protocol that nothing else is allowed to override.

What happens to my email?

The waitlist keeps your email and, if you pick one, the distance you're training for. Nothing else, and it isn't shared with anyone.

One email when your place opens. Bring a race.
