General Course Description
You’ll begin at the Start/Finish and run about an eighth of a mile to the trailhead for the blue-blazed trail. Make a left turn onto the blue-blazed trail and follow it a couple of 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, it will turn into the white-blazed trail 3.5 miles from Lands End 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 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 8:00 AM – 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.
Aid Stations
The Hawk is a fully-staffed race with three aid stations, crewed by experienced UltraRunners. 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
Cut-offs
The 100 and 50-mile races have a Sunday 10:00 AM cut-off for runners leaving the West Park Road aid station after completing the Bunker Hill/Goodwin loop. This is at mile 88 for the 100-mile runners and mile 38 for the 50-mile runners.
The cut-off for Lands End aid Station is Sunday 12 PM, noon. This is at mile 93.5 for the 100-mile runners and 43.5 for the 50-mile runners.
To stay in the race, you must have left the aid station by the above cut-off times. Volunteers will break down the aid station at that time and depart. Runners continuing on their own accord past the cut-offs and not arriving at the Start/Finish on or before the 2 PM cut-off will not be eligible for the finisher awards.
