Targets

Set by race effort. Your paces follow from your threshold pace — about what you could race for an hour.

10K effort

Save it and race efforts become your own paces, from your profile or your Garmin training. Without them every rep keeps its effort cue.

Scaled version

4 × 1 km with 90 seconds' jog.

About this session

What it trains

10K race rhythm — between threshold and VO2max.

Who it's for

10K runners and half-marathoners.

I've been using the AI Training Coach from day 1 for marathon prep and have found it to be a huge step up from ChatGPT/Gemini — I couldn't be happier.
