I’ve got to be a part of a beta for a coaching program, like TrainerRoad I guess, but on more sports, and adding nutrition and other information. It is built by a prior cycling coach, turned airline pilot, and based on ChatGPT, called Samba (no link yet that I know of, I got it off a post on the Zwift reddit). Currently free, not sure if there’s a planned cost down the line.
This is the initial workouts it created for me, with me just tossing things together for it. There are dates on what do do at which workout, but as Zwift doesn’t yet have a calendar built in to schedule such things, I’ve got to read it off the schedule it gave me.

I didn’t give it a bunch of details yet, and didn’t yet ask for nutrition or any of the other advice it can give.
It can also give running, and triathlon plans.
Anyhow, off hand, those look near ideal for my current level… the 30 30s don’t look fun, nor the 40 20s, but a 30 30 that looked fun, wouldn’t be effective. I’ll review it more fully at a later date, at least to what I can from a newbie level. The group ride simulations particularly have me interested, as I’ve never seen those say on Zwift’s own training plans.
I might start with that workout, see how it goes, then adjust it if I start it, and need to give it more information. Then at the end, readjust it if needed, as one checks in at the end, and I can tell it my current numbers, and goals, etc.
And yes, one can make their own plans using ChatGPT, but having it give you the prompts and more details than ChatGPT can give on its own.
