The Castlewood Cup is a true test of trail running stamina with a challenging 15k course in beautiful Castlewood State Park that includes uphill, downhill, switchbacks and creek crossing sections! All athletes receive an official Castlewood Cup hooded sweatshirt and the awards go three deep in each of the 5-year age groups.  Like its autumnal cousin The Skippo, the post race party, on-course hydration and fuel stations make this event top-notch for trail enthusiasts and novices alike! Castlewood Cup has a participant cap and sells out each year, so when registration opens, be sure to sign up early!
