But there were times when the organizer wasn't too sure the event would go as planned. Mother Nature threw out her share of obstacles in the months leading up to the race.
In late June, West Virginia weathered a derecho that left many of Kanawha State Forest's trails blocked with debris. Dolin spent four hours clearing just 2 miles of the course.
With the help of volunteer park rangers, trail runners and mountain bikers, he finally made the trails passable. Then came Hurricane Sandy in late October.
The snow that fell across West Virginia brought down even more trees and limbs than the summer storm, Dolin said.
With the help of more volunteers, the trails again were ready for action.
Dolin said a lot goes into planning a trail race course, including making sure runners have easy access to aid stations throughout the race.
The Frozen Sasquatch had three. Daniel Todd, of Charleston, manned one of the aid stations.
Todd also sponsors a race in Kanawha State Forest in May, called the Dirty Dog 15K. Beside him on Saturday was an open fire where runners could warm up, as well as an offering of sports drinks, water and cola, and what some may see as unconventional sources of energy - animal crackers and M&Ms.
"The one thing about ultra running, that's anything longer than a marathon (26.1 miles) is that after you've been out there for 20 miles, you've used up all your stored energy," Todd said. "You can actually take in calories at these aid stations and feel it work on the next hill."
Alex Wepsala, 25, of Washington D.C., was fond of the aid stations.
"Third time is a charm," Wepsala said. "First year I fell in the river and like almost froze to death. Second year I was really sick and did poorly. This year everything worked out really well."
Wepsala finished first overall in the Men's 50K with a time of 4:32:33.
"We have a few good trails around the D.C.-Baltimore area, but nothing like out here in West Virginia," he added.
Wepsala said the experience was kind of cathartic for him - he was able to accomplish something he had been working toward for so long.
He said it's all about staying focused.
"On the second loop I had rubber legs like crazy," he said. "It was about trying to put everything in a bubble so I didn't think about how much pain I was in and just kept pushing."
Wepsala has already decided where his first prize will be displayed. Each participant received a trophy made of oak - a tree circle base with a running Sasquatch atop, imprinted with the date of the event.
The top three division finishers received an oil painting crafted by Dolin's mother of a Sasquatch running through the woods.
"This is going to go right over the mantle," Wepsala said. "I think my wife has a nice picture there but we're probably going to have to replace it with Sasquatch."
