I always try to have a race I'm training for. My big race now is the Baltimore Marathon in October. Other races I have planned, are just "training runs" on the way to the Baltimore Marathon.
Aaron, you should find some local 5ks to run too to keep you motivated. Maybe you could meet up with Chris or even Don for a race. I've heard really good things about the Indy Mini Marathon (it's a half marathon and there's a 5k with it too), but I guess that's in early May so it won't help you now.
I ran the Expedition Everest Challenge last year (that's the picture of me in the Indy outfit). It was a blast. I really loved it. You can do it individually or in teams of 2. I did it by myself last year, and met up with some of my WISH friends. I said I thought it would be fun to do it with Maggie (because the minimum age is 11). The only thing holding me off signing up for it is the DL half marathon over Labor Day. I'm very curious what the DIS has planned for that weekend, and I'd like to go out for it.
