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, 75-milers two 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, 75, and 100-mile runners, but they will run an additional 1.2 miles at the beginning of the race.
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
The 100, 75, 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, mile 63 for the 75-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, mile 68.5 for the 75-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.
Seeing you cross the finish line is the reason we host this race. If you’ve signed up for one of the events but cannot participate in the Hawk race safely, we offer the following options.
Runners may contact the Race Director and transfer to a lower or a higher distance on or before August 1st. In the event a runner transfers to a higher distance, a pro-rata charge will apply. No credit or refund can be given for runners transferring to a lower-distance race. You can also “EDIT” your registration on ultra signup and change the distance yourself; in the event, you upgrade the distance, the system will generate a code and prompt you to re-register for the new distance. If a race distance is sold out, you will not be able to change to the sold out distance.
The Hawk does not allow refunds or for the runners to transfer entries to other participants. No Transfer Permitted: Race numbers and official participant bibs are assigned by the Race Director to each specific participant and may not be transferred, reproduced, replicated, or modified under any circumstance. You may not: 1) give or sell your number or tag to another person; 2) receive or purchase a number or tag from another person; 3) modify, make copies or other reproductions/replications of your number or bib for any purpose (or allow another to do so); and/or 4)participate with an unofficial race number or bib (i.e., a number or bib that was not assigned to you by the Race Director). Attempting to do any of the foregoing is also prohibited, and any person found violating these rules will be subject to penalties, including but not limited to disqualification and suspension from subsequent Hawk Hundred events.
100 and 75 mile runners may drop down during this race to receive the finisher awards for the lower distance, if available. Dropping to a lower distance must occur at the Start/Finish aid station. If you continue onto the course for any distance and drop later, you will be recorded as a DNF. However, you will not be eligible for placement awards. 100, 75, and 50-mile runners may not drop to the marathon and will be recorded as a DNF in the race results.
Runners may defer their race entries to the following year by notifying the Race Director on or before August 1st. The deferral will not be permitted for any runner making a request less than 30 days before the scheduled event. The race deferral is good for one year only. Requests for deferral must be submitted in writing to the Race Director; given the press of other preparations, runners should make sure their request has been confirmed. The deferral code must be obtained from the Race Director and used within the first 45 days of the next year’s race registration.
If you can’t attend and haven’t deferred, please let the Race Director know at least seven days before the race, so your name can be removed from the starters list. You also have the option to remove yourself from the race on Ultrasignup. If you don’t show up and don’t let us know in advance that you can’t make it, you’ll be recorded as DNS in the race results.
In the event the race should be postponed or canceled for reasons beyond the control of the Lawrence Trail Hawks (Pandemic, inclement or unsafe weather conditions; local, state or national emergency), refunds will not be made, but race packets, including race shirts, will be available at a location to be determined or possibly, though but not guaranteed, by mail.
If local authorities, Clinton State Park and the Kansas Trails Council trail steward, deem the trails unsafe for runners or vulnerable to damage due to muddy conditions, an alternative course will be provided by the Lawrence Trail Hawks race Directors, pending approval by Clinton State Park and the Kansas Trails Council Trail Steward.
