I once went out running at 6.30am during winter, so it was pitch black and nobody around. I came to a bit with no street lights (quite rural) and the Johnny Cash song "When the Man comes Around" came on my ipod. I was terrified! That song is used in the credits of the remake of Dawn of the Dead, so that added to my terror. I ran very fast through that section.
Can't say I've ran late at night before. I would feel a bit strange doing that.
In my previous incarnation at a runner back in the '80s it wasn't unusual for me to go out at 10pm for a 20 mile run... through country lanes! On one such occasion I fell into an unlit manhole (no jokes please!)
I was as obsessed with running back then as I am with chocolate now...
Haven't ever done it. I've tried very early, before getting ready for work, which seemed OK for me. Thing is an early run sets you up for the day, and I would think a very late run would leave me to wired to get to sleep at any reasonable time to get up in the morning.
Latest I've ever finished a run is just before 8 in the evening, but generally speaking I prefer morning runs, usually around 6.30ish, depending on length of run, what time I have to be in work/meet friends (if weekend)... It gets the energy levels up for the day, I reckon if I ran late late at night I'd probably not be able to sleep! PLUS, I really don't have the motivation to run after a full day... sometimes I do, but generally speaking, I just wanna pass out.
