General Course Description

100-mile Start time: 6:00AM. 50-mile Start time 7:AM You’ll begin at the Start/Finish and run about an eighth of a mile to the trail head for the blue-blazed trail. Make a left turn onto the blue-blazed trail and follow it a couple hundred yards to the Sanders Mound trail. You’ll take a left and do a quick 1.1 mile out-and-back to the top of Sanders Mound. From there you’ll get back on the blue-blazed trail and head for the Lands End aid station.

From Lands End you’ll take the RED blazed trail for about 1 mile and then connect with the blue-blazed trail. You will follow the BLUE trail and after you cross the Park road and it will turn into the white-blazed trail 3.5 miles from Lands End 1 at a point known as Cactus Ridge.

The white-blazed trail will take you to the West Park Road aid station. From there, leave the trails and follow the signs, flags, and ribbons along West Park Road, staying on the grass, to Bunker Hill. This is the Goodwin Loop. Complete the 2.5-mile Goodwin Loop, which includes a traverse of Bunker Hill, and return to the West Park Road aid station. You’ll then continue on the white-blazed trail back to the Lands End aid station.

Leaving Lands End you will continue on the white-blazed trail back to the Start/Finish aid station. This completes one loop of the course.

Big Loop: At the Start/Finish aid station, runners will have completed 25 miles (26.2 for marathoners)—what we call the “Big Loop.” Hundred-milers repeat the Big Loop three more times and 50-milers one more time.

When the trails cross: The white-blazed trail and the blue-blazed trail cross at several points on the course. The crossings will be heavily marked and signed, but it is your responsibility to read and heed the markers, signs, and white and blue blazes to stay on course.

Marathon: Start time 8:00AM - runners will follow the same course as the 50 and 100-mile runners, but they will run an additional 1.2 miles at the beginning of the race.
