The problem

Plans don't survive contact with real life

Miss a Wednesday run due to travel, a sore ankle, or a late meeting — and your 16-week plan is already wrong. Generic apps don't know the difference.

📊

Too complex or too generic

TrainingPeaks is built for coaches and elites. Nike Run Club gives everyone the same template. First-timers need something that adapts without a PhD in exercise science.

🏥

Injury from overtraining is common

Most first-timer injuries come from ramping mileage too fast. A plan that can't throttle load in response to real fatigue signals is actively dangerous.

How it works

You train.
We adapt.
Stay healthy.

01

Tell us about your race

Enter your race date, current weekly mileage, and how many days you can run. We generate a 16–20 week personalized plan in seconds.

02

Log your actual runs

Connect Strava or manually log each session. Mark completed, skipped, or modified. Capture how your body felt — easy, tough, or wrecked.

03

Your plan auto-adjusts

Miss a run? The AI re-balances the upcoming week. Crushing your easy paces? Progression accelerates. Training too hard? Load gets pulled back before you get hurt.

Built for first-timers

Everything you need.
Nothing you don't.

Adaptive weekly updates

Your plan reshapes around your actual week, not the week you planned. Missed runs redistribute. Pacing zones update based on your current fitness.

📈

Progress tracking

Visual weekly load graphs, pace trend charts, and fitness readiness scores. Know exactly where you are in your training block at any moment.

🛡

Injury prevention

Load management is non-negotiable. The system monitors weekly mileage ramp rate and flags recovery risk before you feel it in your knees.

🎯

Race-date smart planning

Built around your actual race date. Taper begins automatically 2–3 weeks out. The plan knows exactly how many weeks you have and protects them.

🔄

Real-life flexibility

Travel, illness, late nights — log what actually happened and the plan adjusts forward without drama. No shame, just math.

📋

Guided pacing

Easy, tempo, interval, and long-run paces are calculated from your current fitness — not a generic chart. You always know the right effort for each session.

vs. the alternatives

Simple enough to actually use.
Smart enough to matter.
