So I'm doing the ING Hartford Half Marathon on October 12th. Very excited about it. But I found a half marathon that's taking place on September 15th that I really want to do cause it's right near my house. My training would have me be doing long runs up until the week before the Hartford race, which would include doing 12-13 mile runs once a week. If I switched my training days up for that week and did my long run on that Sunday instead, do you think it'd be good? I don't plan on killing myself doing it and will definitely take my time but I think it'd be fun to do this other half. What are your thoughts on it? Like I said, my training schedule has me doing a long run on Friday. For that weekend, I'd probably take that Friday off, giving my body like 3 days rest before it. I'd have to change that one week after the September race.
