Wa Wa Splash and Dash Duathalon, Southfield

At YMCA Camp Wa Wa Segowea, 500 acres of forest encircle placid Harmon Pond—and during the Wa Wa Splash and Dash Duathlon, athletes make the most of the terrain. At the race's start, they swim the 400 yards across the pond. Next, they run 3 miles through the forest, earning extra points for running up and over trees. When they finally reach the finish line, they stop for festivities featuring refreshments, a raffle, and an awards ceremony.
