Triathlon.

Swim, bike, run and strength on one calendar, with what was asked next to what was done.
The season by phases and the countdown to each race.
Fitness, fatigue and form over time.
Every workout as a file: .zwo for the trainer and .fit to copy to your watch by cable.

You connect the AI you already use, it reads your history and writes the week to the calendar. You can try all of it before you subscribe.
