What happens when...

You run faster than planned

Your next workout intensity increases. RunRight recognizes your fitness is improving and adjusts upward to maintain the right training stimulus.

Growth rate: pace increases by 1.15–1.20x progressively

You run slower than planned

Your next workout intensity decreases. This prevents overtraining and injury. The plan respects that some days are harder than others.

Recovery is adjusted, next week's volume is moderated

You miss a scheduled run

The plan recalibrates your timeline and volume. It doesn't just skip the workout — it redistributes the training load across remaining sessions.

Distance decay: 10% per week of inactivity

Your VO2Max changes

When Apple Watch reports a new VO2Max reading, RunRight recalculates your baseline fitness and adjusts all future workout paces accordingly.

VO2Max model uses exponential decay to weight recent data

You exceed your weekly distance

Recovery is adjusted and next week's volume is moderated to prevent overtraining. RunRight monitors training load across three dimensions: distance, fitness, and strength.

Impact levels: minor → maintaining → improving → highly improving → overtraining

The Science Behind Adaptive Plans

RunRight's algorithm is built on VO2Max-based fitness modeling with exponential decay. This means:

This isn't a chatbot generating generic advice. It's an algorithm trained on the same physiological principles that coaches use — but with access to every data point your Apple Watch records.
