The Capital Backyard Ultra offers an exciting challenge, serving as a Golden Ticket Event for the World Championship Backyard Ultra, granting the victor an entry to the prestigious Big's in Tennessee, along with a travel stipend. Set in the serene backdrop of Potomac, MD, this race features a unique course comprising a 4.167-mile loop that blends single-track trails with road paths, allowing participants to potentially cover a hundred miles in a 24-hour span. The race adopts a distinctive format where runners embark on a new loop at the top of each hour, marked by a series of whistles and a ringing bell. While the rules are straightforward, the race tests the limits of endurance. Only the last runner standing completes an additional loop to claim victory, while all others will know they pushed their boundaries, making the experience both a personal battle and a test of tenacity.
