The OBX Marathon is an almost completely flat point-to-point course. There are two points of course elevation. The first is in Nags Head Woods Preserve around mile 12 of the marathon course. The second is crossing the 35 foot tall Washington-Baum Bridge leading to Roanoke Island at mile 23. The bridge is tall (stats: 1.05 mi long, 82' high, with a 650' climb to the top at a 4% grade).
In addition to those two changes in elevation, part of the marathon course is on a trail. The first section from about mile 10 to 12.5 is on a packed dirt road through the maritime forest of Nags Head Nature Preserve. The other section at about 12.5 miles runners leave the Preserve and get back on the road via a narrow, more difficult sandy trail.
The course can be fast, but wind, trail sections and the climb up the Washington-Baum Bridge near the end of the race (approximately mile 23) can be challenging.
