Hmm, sounds like a group ride. Which is why I’ve only done a few locally, I get a bit antsy when we’re always stopping, then sitting around in a cafe. Great if you’re socialising but understandably frustrating if you’re training I think.
Actually it highlights something I don’t think is fully covered by TrainerRoad. If I’ve got a 4.5hr workout and I take a bunch of breaks then Adaptive Training figures this is a failed ride. In reality, I don’t think there is much science to say you aren’t benefiting as much by taking breaks. Take swimming - rest breaks are standard and improve form and overall quality. A 1.5h break in an endurance ride might seem huge but I’ll bet the physiological adaptations might even be better for some with a break in between.
