How do you organize your route/effort for trainerroad workouts outside?

I live in the city, so navigating the maze is my warm up/cool down.

It depends on what your goal is. For interval work, I don’t think this is a good approach, at least not for most types of intervals. But I think there are good ways to bring purpose to outdoor work.

What I like to do is set myself challenges or jobs for outdoor rides. For example, on rides where I try to optimize pacing to maximize overall speed, I know I will have to reign myself in on the climbs a little and push myself on the flats. On other days, I don’t want my heart rate to go above 140 bpm (a Z1–Z2 ride). Or I pick one hill where I want to smash it and casually ride the rest of the way.
