I am a road racer, but I wanted a new challenge. I got one with the Dunes Heavy Half (14.4 miles). There is also a 50K. It is run in beautiful Jonathan Dickinson State Park. The production is very well organized and there is a very chill vibe. There was ample food and water/hydration at every aid station and at the start/finish line. The race did start late, but it was not the race director’s fault, as the timers (who also had the bibs) were in an accident on the way over. It was about a 30 minute delay, but no one seemed to mind. The race is on grass roads, single tracks, boardwalk, and sand! Lots of sand! The half went over the “Dunes from Heaven” and the 50K goes over even more. The trail is more technical than I would have thought, lots of roots to watch out for. I did trip, so be careful. People on the trail were super nice and supportive of every racer. Most of the race (I was the back of the pack) I was alone on the trail or with just 2-3 other people. The trail doesn’t offer much shade and the race being at the end of April gets warm. The volunteers were super awesome and they took care of you and made sure you were drinking enough. The metal was a nice wood metal and you got a shirt. The top finishers got hand made trophies. Not sure trail racing is for me, but I am glad I did it and it was a fun challenge. I would suggest it to anyone who wants to do a trail run.

I’ve been racing for over 30 years and have completed over 1200 races all over the country, including over 100 marathons and ultramarathons, and this race ranks right up at the top. From pre-race amenities to the course to aid stations to the abundant food and beer to the entertainment and everything in between, this is just a fantastic event!
