Stop re-explaining yourself. Athmex gives Claude or ChatGPT your goals, PBs, races and the week you really have, so every training plan and session is actually built around you. It even lets you connect your training data for analysis after each session.
You. Your fitness. Your activity data. Together in Claude and ChatGPT.
ChatGPT and Claude already know endurance training. Athmex gives them the goals, numbers and real-life context that make the coaching yours.
I’ve got 40 minutes on Thursday. What should I do?

Happy to tailor it. What are you training for, and how far are you running at the moment?
Sunday’s long run3 is the priority on the way to Brighton1, so Thursday adds time on your feet without taking anything out of the legs you’ll need to go past 26 km2.
ChatGPT, using what Mark told Athmex.
His first marathon and his running week were already there, so the conversation started with the session.

To make it more specific, what are you training for and what pace are you running now?
It practises 19:59 pace2, a step on from your 20:481 and just quicker than threshold3, and leaves your legs fresh for Saturday4.
Claude, using what Ben told Athmex.
The same 40 minutes, built around sub-20, Saturday’s parkrun and a calf that needs looking after.

Tell me your next race and your current times and I can tailor this.
Seven weeks from Manchester2, it banks sub-3 pace, a clear step on from 3:12:401 and comfortably slower than your 4:02 threshold3, so Saturday’s long run doesn’t suffer.
Claude, using what Marcus told Athmex.
Manchester and his 7am cut-off were already known, so the coach went straight to the work.
