Inside your plan.

Your plan adapts as you train based on what you actually did and how you're feeling — not a fixed PDF written months ago.

01

A plan shaped to your goal

Pick a goal — race, distance, fitness milestone, or “feel better.” The AI builds the right training blocks, chooses the right paces and intensities, and works backwards from your target date.

  • Targets the demands of your exact event, not a generic template
  • Adjusts weekly volume to the time you actually have
  • Adapts to your gear: treadmill, trainer, pool, trails, dumbbells
  • Change goals any time — the plan rebuilds in about a minute

02

Strength and limiter blocks

Your AI coach spots the weak link — bike legs for a duathlon, sighting in open water, long-day fuelling for gravel — and drops in a focused block to fix it before race day.

  • The AI focuses on the limiters it sees in your training data
  • Short, focused blocks (e.g. "run bootcamp", "swim technique series")
  • Strength and mobility tuned to the demands of your sport
  • No nasty surprises on the start line

03

Always aligned with real life

Travel weeks, work crunches, a new baby, a head cold. The AI rebuilds the plan around you — without losing the thread to your goal.

  • Tell the app today’s constraints; it adapts your day
  • The AI eases your load when your training stress signals fatigue
  • Skip days without blowing up the plan
  • Chat with your AI coach about anything, anytime

A week in your plan.
