Capital Backyard Ultra

The Capital Backyard Ultra is a challenging endurance running event held at Meadowood Special Recreation Management Area in Lorton, Virginia, near Washington DC. This unique race features a 4.167-mile loop that starts every hour on the hour, with runners required to complete each loop within the hour to continue. The event continues until only one runner remains, who must complete an additional loop to win.

Limited to 60 participants, the race offers a supportive atmosphere with experienced staff and volunteers. The 2026 event, a Silver Ticket race, takes place in late March to benefit from cooler temperatures, with a $1,000 prize and a special finisher’s award for the winner.
