Lace up your running shoes and get ready to celebrate mathematics and motion at the annual Pi Day 5K and 10K, set to take place on March 14, 2026, in Annandale, Virginia. This popular event, hosted by Bishop's Events at scenic Wakefield Park, offers runners a chip-timed 10K race, with a 5K option also available. The course winds through Wakefield Park and extends towards Byron Avenue Park, promising a refreshing and engaging run.

Participants in the 10K will find four well-stocked water stations along the route, strategically placed around mile markers 0.9, 2.3, 4, and 5.4, with Gatorade available at some stops to keep you hydrated. Restroom facilities are conveniently located inside the Wakefield RECenter. Typical race day conditions in mid-March often bring crisp air, with highs around 53F and lows around 32F, and only a 12% chance of precipitation, providing ideal running weather.

Beyond the course, the Pi Day 5K and 10K offers a unique festive atmosphere. Every finisher receives a commemorative medal, a technical event shirt, and to truly embrace the "Pi Day" spirit, a celebratory slice of pie post-race. The event is also part of Bishop's Events' year-long and winter series, contributing points for those participating in multiple races. Parking is readily available at Wakefield Park near the Wakefield Park & Ride (8100 Braddock Rd, Annandale, VA 22003), and race day registration is offered, though arriving an hour before your 6:00 PM (10K) or 6:30 PM (5K) start time is recommended for packet pickup.
