Devil Dogs 100 kilometer ultra marathon Triangle, VA.
This loop course is primarily single-track trails, with occasional roots, rocks, and brief technical sections. There are also spurts of fire road and rolling hills but no substantial climbs. The first loop for both races is 23 miles, and subsequent loops are 19.5 miles. The 100k will complete three loops, and the 100-miler will complete five.
Runners have 20 hours to complete the 100k and 32 hours to complete the 100-miler. There will also be cutoffs during the race itself — a chart with times is in the aid station section below. Aid station captains have full authority to enforce cutoffs and prohibit any runner they deem medically unfit from continuing onward.
