I’m an evening runner and it works for me but I think I’ve just been conditioned this way almost my entire life. Maybe not 8PM late, but sometimes. High school, practices after school and nighttime when we had to share the gym. College as a D1 athlete - some morning workouts but most were after class, and games could go until 8-9PM. Grad school, I preferred to take earlier classes and work our afterward. So it’s just always been what I’m used to. I follow a rigorous training schedule so I have no trouble falling and staying asleep.
