I don't know how many people on here are runners in addition to triathletes, but for any runners looking for a race next June, the Hatfield-McCoy Marathon and Half-Marathon is AMAZING!
It's on the Kentucky/West Virginia border, and its by far the best race I've ran. I did the half yesterday, PR'd and won my age group, which is great because its a small race so winning is easy :). The race volunteers are by far the nicest I've encountered, and the landscape is beautiful. It's REALLY hilly, so it's a great workout (I have no idea how I ran a PR yesterday, but I'm pretty siked about it!!). None of the other races I have done I would feel strongly enough to rave about, but this one is really special.
If you are looking for that distance in June next year, I will see you out there. I've done it two years in a row, and I will definitely be back again next year, maybe to attempt the full. This year I took a friend, and she's addicted as well and pledging to go back again.
