Urban Environmental Challenge

Looking for a great trail race this weekend? Look no further than Van Cortlandt Park, where the Van Cortlandt Track Club is putting on the Urban Environmental Challenge 10K that wends through the trails of the park. Last year's rendition was the same weekend as the Boston Marathon - and the major storm that ripped through the region, meaning that half of the trails were under water (making the race a total blast). Sign up through Active.com or on race day.
