The Greensprings 24 returns to Williamsburg, Virginia on October 24th, 2026 for its fourth annual iteration as an endurance race that challenges participants with a full day and night of running or walking along a scenic trail. Starting at John Tyler Highway in the heart of Williamsburg, this event offers runners a unique opportunity to explore their limits over a 24-hour period. The course is designed around a USATF-certified loop trail measuring exactly 2.215 miles per lap, allowing participants to set personal goals such as completing a marathon or aiming for one of several milestone distances including the full 200-mile mark. On race morning in Williamsburg, runners can expect cool temperatures and mild conditions typical for early October, with an average temperature hovering around 16.4 degrees Celsius. The trail remains firm yet slightly soft underfoot due to crushed gravel surfaces that are easy on joints but provide a stable base throughout the event's long hours of operation from Saturday morning into Sunday morning. Participants will find ample opportunities to rest and refuel at regular intervals along the route, where volunteers ensure safety with reflective streamers marking each lap clearly. As part of Williamsburg’s vibrant athletic community, The Greensprings 24 has become a significant annual event supporting local initiatives such as The Arc in Williamsburg, VA. Since its inception, this race not only fosters endurance and camaraderie among runners but also raises awareness and funds for adults with developmental and intellectual disabilities through direct donations collected during the registration process or on-site contributions.
Registration for The Greensprings 24 can be completed online at https://ultrasignup.com/register.aspx?did=135991 with an entry cost of $115. Early registrants who sign up by October 8th will secure their preferred T-shirt sizes, ensuring they have the right attire for race day in Williamsburg. Packet pickup is available on Friday evening between 4-6pm at John Tyler Highway or immediately before the event starts from 6:30am onwards on Saturday morning. Participants are reminded to bring valid ID and any additional donations for The Arc if planning to contribute directly. The start location, located precisely at 3751 John Tyler Hwy in Williamsburg, offers convenient parking options right next to the trailhead where runners can set up their gear for an overnight stay. Age requirements permit anyone over 18 years old to participate, though younger individuals interested may inquire about special arrangements or youth-specific initiatives within The Arc’s programs. The Greensprings 24 in Williamsburg is a testament to community spirit and endurance challenge on the picturesque trails near John Tyler Highway from October 24th through early morning of October 25th.

About Williamsburg
Learn more about the host city, Williamsburg.
Williamsburg is a city in southeast Virginia. Settled in 1632, it was the capital of Virginia from 1699 to 1779 and in 1926, John D. Rockefeller Jr commissioned a restoration project to bring Williamsburg back to its former colonial glory. During this period, 700 modern homes were demolished, colonial buildings were renovated, and more than 400 buildings were reconstructed on their original foundations. Today, the Colonial Williamsburg district in the center of town is a popular tourist center and people visit in droves to immerse themselves in the nation's colonial history.
