South Lakes 10K & 5K September 27, 2026

The South Lakes 10K & 5K hit the roads around South Lakes High School on Sunday, September 27, 2026, delivering an incredible morning of community fitness and neighborhood pride. Serving as the perfect wrap up to a long summer of training, this standout stop on the PR Race Series drew an energetic crowd of runners, walkers, and local families eager to conquer a true community favorite. The lively morning air was buzzing with energy well before the starting horn sounded, making the entire school campus feel like a giant celebration of local health and athletics.

The event featured a dynamic race environment for everyone involved, offering both the premier 10K distance and a fast paced 5K option. Excitement peaked early as participants gathered near the high school where the vibrant start lines were positioned. A moody, overcast sky brought cloudy conditions and a steady autumn rain early on, but the wet weather could not dampen the fiery spirit of the participants. Runners leaned into the challenge, splashing through the puddles and using the cool, rainy elements to their absolute advantage as they pushed their limits. The slick asphalt only added to the dramatic, high energy atmosphere as athletes tackled a scenic, rolling neighborhood course that wound directly through some of Reston's most beautiful tree lined streets.

By the end of the race, the rain was beautifully clearing and the sun was finally coming out to welcome everyone to a spectacular finish right on the high school stadium track. Participants crossed the line into the sunshine completely drenched but wearing massive smiles, taking home custom commemorative shirts, unique finisher medals, a bounty of post race snacks, and free high resolution race day photos to capture their triumphant moments. Top age group and overall finishers were recognized with digital finisher certificates and awards ceremonies, highlighting the elite competitive drive that local runners brought to the course.

Beyond the race day swag and personal achievements, the South Lakes 10K & 5K carries a deeply impactful purpose. The event serves as a vital fundraiser for the South Lakes High School Cross Country team, with registration proceeds directly supporting the student athletes. Funds raised help provide the team with essential training resources, travel opportunities, and championship meet gear for their upcoming season. By bridging regional fitness enthusiasts with the local high school athletic program, the race has become a powerful tradition that directly champions the next generation of Reston runners.

Whether you came out to test your endurance against the elements on the neighborhood hills, snap photos of the relentless community determination, or give back to our local high school athletes alongside your neighbors, the 2026 race was a massive success.
