The Dashing to Summer's End 5k & 10k returns on September 12th in Alexandria, Virginia, United States. This event offers a scenic 5K and a challenging 10K paved course along the Mount Vernon trail, which provides runners with stunning views of the Potomac River. Race morning brings cool temperatures that hover around an average high of 70°F (21.4°C) and a low in the mid-60s (16.8°C). The sky promises plenty of sunshine, casting a natural glow over the course as runners make their way through Alexandria's charming neighborhoods, passing by Mount Vernon’s historic grounds. This running celebration has been part of the community for five consecutive years, drawing hundreds of participants annually who come to support local charities and scholarships. Runners can choose between the 5K or 10K routes, with both distances offering a mix of paved paths along the riverfront and through quaint Alexandria streets. The race course is set on hard and dry pavement, making it suitable for all skill levels. The route starts at Washington Avenue and follows the Mount Vernon trail before heading back to the starting line via Queen Street. There are no marked aid stations this year; however, runners can take advantage of water stops along the way. A slight elevation change isn't expected given the flat terrain. The weather on race day will feel comfortable with temperatures ranging from a minimum of 62°F (16.8°C) to a maximum of 79°F (26.1°C). The humidity is around 73%, which should be manageable, but runners are advised to stay hydrated throughout the course. A gentle breeze with an average speed of 5 mph (9.1 km/h) might make for slightly cooler conditions during your run. The race offers a variety of distances: the 5K and 10K paved courses; virtual options such as the Virtual with Medal, Virtual with Medal and Shirt, or Virtual without Medal/Shirt. Registration fees range from $33.63 to $49.64 depending on the distance chosen.
