I'm stuck in a kind of running funk: I don't know what I should train for/work on next. Speedwork? For what? Another 5K? Should I train for a 5K? Or should I start working now on my sometime goal of running a marathon? But which one?
Also:
How many miles can my legs take a week?
Also:
Did I destroy them by running the 5K and then running (eventually) 4 times the following week?
So many questions...
