The course is a “lollipop”: the first 1.5 miles is the same as the last 1.5 miles. The rest of the course, after 1.5 miles, is a 7 mile loop. The last mile is downhill to the finish. There is one road crossing in the 10 mile course. Most of the course is concrete bike path. There is one 2 mile section of double track, and a mile of crushed gravel. The 5k and 10k are “out and back”, and all on the bike path.
