The only running tip I have is to think of miles run like a bank. Every time you go out you're putting money into the bank. When you skip a day you're taking money out. Everyday you skip it's a little bit harder when you go out the next day. So be jealous of the opportunities to go out. Don't cheat yourself by skipping but put a few more pennies in the bank instead.

I'm not super gung-ho though - I think I run 20 miles a week maybe - just 5 or 6 days. And I always take a day off. But it works for me.
