When using plan builder, it would be cool if TR allowed us to select a specific race rather than a discipline.
I would imagine TR has data from people who have raced specific events -including data on course profile and power profile from pro riders. The course profiles for the lutsen 99er and leadville are different and therefore might require different training. Rather than me selecting XCO, I could select lutsen 99er and it would choose the appropriate training plan. Maybe in triathlon it wouldn’t matter, but I know many ironman courses have very different profiles as well.
They couldn’t get rid of discipline altogether because people don’t train for events and they wouldn’t have data for them all, but I still think this would be a nice additional feature.
