Every running app has the same flaw
A runner gets sick for a week mid-training. Every app keeps the same plan as if nothing happened.
01

Static plans

Current solutions generate plans from limited inputs and never adapt based on how your body is actually responding.

02

Manual effort

Athletes are left to research, restructure, and personalize their own training — or just wing it and risk injury.

03

Coaching is expensive

A human running coach costs $150–400/month, putting expert guidance out of reach for most runners.

A plan that evolves with your body
AI-powered adaptation

Our algorithm ingests HRV, heart rate recovery, sleep, and training load to adjust your plan every day.

Proven coaching science

Built on the principles of Daniels, Hansons, and Higdon — the gold standards of distance training.

Human-validated

Every AI-generated plan update is reviewed by human running experts for safety and quality.

5K to marathon and beyond

Starting with running. Expanding to conditioning for soccer, tennis, basketball, and all sports.
