Ideally, this would also need pace bot which you can pass as well rather than be braked by

I've refined this request to make it simpler to implement and to cover some wider use cases:

The power is almost completely in the ability to have a pacer follow a workout file. Fit files from previous activities can be converted to workout files using https://sport-calculator.com/converters/fit-to-zwo to further expand the possibilities.

Please excuse the extremely crude mockups.

Event creation > Group ride > add pacer bot > configure pacer

Configuration options: Select workout, pacer FTP, pacer weight, Draft enabled>yes/no

Use Cases

Blind workout - do your scheduled workout without prompts by sticking with the pacer bot for full immersion (Draft off, match your FTP/weight, add a few bots)

Hill efforts - go ******* the hills and recover on the flats (workout file with constant effort, set very low bot weight with similar FTP to you)

Moto pacer - a couple of bots and a steady effort workout file

Progression - workout file that steadily ramps up power. Stay with the pacer as long as possible

Draft practice - High power heavy pacer with around 20 bots on a flat course. Position well to not get dropped

Sprint lead out practice. Pick a workout file that matches the course selection to ramp up power before the finish line (a few bots)

TT / hillclimb ghost - use your last effort as the workout file and try to beat it

Race simulation - use a fit file from a previous race and try to beat yourself

Course workouts - community created workouts that match a particular route parcours - e.g. hard hill climb followed by a sprint finish

Fartleks - load up a workout with some random efforts and stick with the pacer

Beatbiker music workouts - pacer will match efforts to a particular album or playlist!

This sounds awesome. Especially if I can pick a whole group of workout bots.
