PR Birthday Bash 5K

Get ready to celebrate fitness and community at the PR Birthday Bash 5K on Sunday, July 19, 2026, in Fairfax, Virginia. This vibrant event, marking Potomac River Running's 22nd anniversary, promises a lively atmosphere for runners of all levels, featuring both a 5K race and a 1K Fun Run, along with virtual options. The race kicks off at Fairfax Corner, 11895 Grand Commons Avenue, offering a convenient start and finish point with ample parking.

Runners can expect a paved and wide course through the Fairfax Corner area. While generally accessible, a past participant noted that the summer conditions—including heat, some hills, and limited shade—can make it a challenging yet rewarding experience. Typical race day conditions in mid-July include highs around 86°F and lows around 67°F, with a 13% chance of precipitation, so preparing for warm weather is advisable.

Beyond the race itself, the PR Birthday Bash is a true celebration. Participants will enjoy an exclusive soft-style =PR= t-shirt, a unique race bib, free race day photos, and a digital finisher certificate. The festivities continue post-race with cupcakes, raffles, and engaging activities from various brands, creating a memorable community gathering in the plaza. Awards will be presented to the top three overall male and female finishers, as well as the top three age group finishers in five-year increments, with medals for all 1K Fun Run participants. Packet pickup at the local =PR= Fairfax store offers an opportunity to get race-day essentials and soak in the pre-race excitement.
