I only ran three times this week, but each time I ran a half-marathon distance. I don't know if this is a better approach than running 5 times per week and, you know, not running a half marathon each time, or whatever. I had a brief moment in the shower where I said to myself "100 halfs in 100 days" and then quickly, literally, laughed aloud at the prospect.
So I'm sure at some point this year or next year I'll give it a try.
