Targets

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

5K effort

About this session

What it trains

5K race rhythm in slightly shorter pieces, so the pace stays crisp.

Who it's for

5K runners of every level.

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.
