One option could be to switch the routes covered by the Pacebots on a weekly basis, allowing for a more dynamic and varied schedule.
It wouldn't be necessary to provide a "family" of Pacebots.

Yes! Basically higher wattage pacers on the flat courses.

The stronger pacers typically use more lumpy routes, which makes some sense - however while the pace on the climbs is good, it's then followed by a long period of super easy spinning down the descents. If you keep the power on, you drop the pacer and have to try and regroup.

It would be really good to have a pacer which hits those same numbers on the climbs, but maintains the power on the descents or has shorter/shallower descents between ramps, giving a more consistent workout.

This is a great idea. I use the pace bots for my zone 2 rides and a bit of variety in the routes would be a welcome addition.

Hello, I am using the pacer bots for aerobic rides, warming up and ideally TTT practice. The issue is that the faster bots are only on hilly courses, so if you happen to join them when they're descending a mountain it's not the greatest warmup/training.

My suggestion is a flat/rolling/hilly course for each pacer, so if you want a certain type of workout you can join the right group for that. To reduce confusion, it could possibly be a sub menu in the style of "what pace do you want to ride today? > what terrain do you want to ride today?"

I know I could set up an event to achieve all the above but a simply accessible version from the pacer menu would be great. It would also be familiar to those coming from a certain other platform, which has pacers on a wide variety of courses.

Variety being the spice and all.
