It should be a walk in the park, or perhaps a run.

Lawrence Trail Hawks will host 100-mile and 50-mile races as well as a marathon Saturday and Sunday, at Clinton State Park, 798 N. 1415 Road, Lawrence.

“Everyone’s going to read this and think we are crazy,” said race director Danny Miller. “But it’s fun. It gives people the chance to go out in nature and clear their head.”

The races will be run in a 25 mile-loop at Clinton Lake and there will be three way stations set up to provide aid and food to the runners.

“We will have food going all the time. You can’t run something like this without going through a lot of calories,” Miller said. Miller added that most runners will walk at least 50 miles of the 100-mile race.

The top three finishers in each race will receive rewards; those finishing the 100-mile race in less than 24 hours will receive a belt buckle.

Registration costs $70 for the marathon, $75 for the 50-mile race and $140 for the 100-mile race. Race participants will all receive a T-shirt to commemorate the event.

Miller said that the group is putting on this race, in part, to help Clinton Lake State Park and will donate part of the proceeds to the park.

“We like to give back,” he said. “We also really like the trails.”

The marathon will begin at 7 a.m. Saturday. The 50- and 100-mile races will begin at 6 a.m. Saturday. “No matter what happens everyone that goes out there are going to have a good time,” Miller said.
