About the Busse Woods 20 Miler - 7:00a.m.
The course runs through Busse Woods, a forest preserve outside of Chicago that gives you miles of tree cover and a mostly flat path underfoot. It is designed as a long training run rather than a race, self-timed, with aid stations spaced out along the route so you can practice your fueling and hydration exactly as you plan to on marathon day.
Parking is free and easy near one of the forest preserve's picnic groves. There is a celebration at the finish with refreshments, which is a welcome thing after that kind of effort.
