The 3.7 mile off-road loop means your race can be just over 5k or even over 50k and anywhere in between. You decide how many laps you're going to do on the day within the 6-hour time limit. If you're looking to cover a marathon distance you'll need to complete 8 laps and a half marathon will be 4 laps. The course isn't flat but there aren't steep inclines. Each lap has around 160ft of elevation, making the marathon distance 1280ft of elevation.
