I find the pace partners too problematic to follow. (edited to avoid confusion)
People do not ride like them, not by a longshot!
In every single climb, diesel dan slows down like he hits the brakes, and when you hit the top, i often have to get out of my seat and push 4-6wkg just to keep up as he’s really going at it.
I find it nearly impossible to stay with it and when i loose the partner, well it kinda ruins the experience and workout.
My suggestions to improve them (constructive feedback)
Make the follow area bigger (a few meters more)
Make him more visible when you have chosen “ride with pace partner”
Make him slow down slower on the climbs, keeping his momentum longer.
