Training for an ultramarathon requires a lot of hours out on the trail. It also requires time in the gym. But when you are an ultramarathon runner and an obstacle course runner, it requires a lot of time both running and in strength training.

Devin Nelson is both an obstacle course runner and an ultramarathon runner. And he says that his training plan is the Dad Training Plan. He squeezes in his workouts wherever he can between working and being a dad and husband. He finds a way to get it all done. He has several 100-mile finishes to his credit and this year competed in the World's Toughest Mudder 24-hour obstacle course race.
