Ogr44 I'm midpack runner also and the Virginia beach half was my first hm. Loved it too. Did the inaugual Maui Half in 2004. It was my 20th anniversary gift from my wife. It's my favorite of the islands. Highly recommend this one. Well run and great scenery as you run along the coast most of the way. Also did the Niagara Ultra. I ran the marathon but they also have a 10k, a half, and a 50k same day. I really enjoyed this one with the falls and all there is to do and see there. It was on the canadian side. I also hear the Disney one is great too. This one is on my bucket list. You mentioned you hiked at Virginia beach. If you like a good challenge and a great time you may want to give the Magatransect in Lock Haven Pa. a try.It's 25.5 ran through Bald Eagle Mountain State Forest. It's a small town so don't look for alot to do other than the forest but if you like this sort of thing you wont have to. Awesome race with unbelievable scenery. The people are the greatest anywhere and the post party is amazing too. Registration for this is January 1 and this year filled up in 48 hr. Over 900 people can't be wrong. Hope this is a help.
