Anyone successfully tried chat gpt as coach for 100k ?

After seeing this video : https://youtu.be/uSXDXIwtYis?is=3unXmmR7y5--eO1w
I thought I’d give it a go . I had running coach for last 3 months or so . I put his weekly plans and my garmin data (last 6 months) into sources. I used all prompts from video it was going very well (took me 1-2h) but in the end chat gpt got distracted with how pretty/ good it wants to make google sheet 😂 so fingers crossed it will work ok .
Anyone tried AI planner for longer races ? How did it go ?
This year I’ve done: 55k 1500m , 65k 2600m , BYU only 7 laps , sky running 50k 2500m . Planning to do first 105k 4000m in October.
