Course Markers

The course is marked with flags and ribbons. There are also right-turn, left-turn, straight ahead, and wrong way signs. The course is designed so that you can follow it using the Park Department’s blazes on the trees, except on the out-and-backs to Bunker Hill/Goodwin Loop and Sanders Mound. The trail will be marked with reflectors during the night portion of the 100-mile race. You must have a headlamp or flashlight in order to see these.

This, of course, is a trail race. Part of a trail race is making your way on the course. We will do our BEST to make it difficult (even for the most bone-headed among you) to get off-course. That said, wind, animals, vandals or your own blurry vision may cause you to miss a marker or a turn and we’re not looking to paint the entire course orange.

Trail Blazes

In addition to signs, flags and ribbons, runners should also watch for the white, blue and red blazes on the trails. The westerly, out-bound portion of the course is marked with blue blazes. A one-mile detour along the Clinton Lake shoreline will be marked with red blazes. When the course turns back east toward Lands End, it will be marked with white blazes.

In addition to the white, blue and red blazes on the westerly, easterly and shoreline trails, you may see trails marked with both white and blue or red and blue blazes. These are “connector trails.” Do not follow them. They will be marked with wrong-way signs and/or ribbons, but in case the signs get knocked over or vandalized, please know you should follow only SINGLE white, blue or red blazes as shown in the photos.

Course Description

100-mile and 50-mile races: 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 where you will find a hole punch for your bib. 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 shoreline trail until it meets back up with the blue-blazed trail. The blue-blazed trail 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.

Marathon: Marathon 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.

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, blue and red blazes to stay on course.

Aid Stations

The 2015 Hawk is a fully-staffed race. Aid stations will feature water, sports drinks, and typical aid station snacks. Following are the locations and distances runners will hit aid stations as they traverse the 25-mile course (26.2 for marathoners).

  • Lands End: 4.5 miles – no crew access, drop bags
  • West Park Road: 10.5 and 13 miles – crew access, drop bags
  • Lands End: 18.5 miles – no crew access, drop bags
  • Start/Finish: 25 miles – crew access, drop bags


The 100- and 50-mile races will have a 32-hour cutoff, ending at 2 pm on Sunday, September 14th. The marathon has a 31-hour cutoff, ending at the same time as the 100- and 50-mile races. There are no aid station cut-offs.
