Advice for returning to V02 Max/aerobic/ Intervals

I broke a big toe and took two months off running. I’m now back to running (shout out to REVO Return to Running Guide). Having completed the phases of the guide, I want to jump back into speed and strength workouts to rebuild the aerobic capacity and hill/mountain running strength. I attempted Roche’s “Corrine’s V02 Hills” workout (5x3:00 moderately hard), and was really feeling the cardio burn. Maybe i just needed to dial back the effort a little.

I’m wondering what kind of workouts you think might be best to ease back into speed/strength/aerobic development work? Shorter intervals? I ran a 7.5mi / 1600’ vert route last week which felt good-hard, but that was more of a steady long run effort. I’m just feeling a bit lost, i haven’t taken this much time off running since I’ve gotten into the sport so it’s all a bit disorienting. Cheers
