VirtualIncl. $1.60 Fee
25K Virtual Challenge The 25K Virtual Challenge invites participants to complete 25 kilometers (15.5 miles) in a single activity anytime between July 410, 2026. Whether you're chasing a personal best, maintaining your training while traveling, or simply looking for an opportunity to participate in a race during a busy holiday week, this challenge is designed to meet you where you are. One of the best things about virtual racing is the flexibility it provides. Maybe you're visiting family. Maybe you're staying at a lake house. Maybe you're spending the week at the beach, in the mountains, or somewhere so remote there isn't a local race within 100 miles. With the 25K Virtual Challenge, you can still enjoy the holiday, spend time with family and friends, and complete a meaningful race on your own schedule. How It Works Complete 25 kilometers (15.5 miles) in one continuous activity Run, walk, hike, or use a treadmill Complete your challenge between July 410, 2026 Submit your results Receive your digital finisher certificate Participant Perks check mark Digital Race Bib check mark Digital Finisher Certificate check mark Official Finisher Listing check mark Social Media Finisher Badge check mark Optional commemorative apparel available for purchase

250 Minute Challenge
VirtualIncl. $1.30 Fee
250 Minute Challenge Not every challenge needs to be measured by a finish line. The 250 Minute Challenge celebrates America's 250th anniversary by encouraging participants to accumulate 250 minutes of running, walking, or hiking during event week. Unlike the 25K Challenge, your 250 minutes do not need to be completed all at once. Complete them in a single long effort or spread them across multiple activities throughout the week. Participants are encouraged to track both their time and mileage. Some will focus on simply reaching 250 minutes of movement, while others may challenge themselves to see how many miles they can cover within those 250 minutes. Whether you're spending the holiday at the beach, visiting family, relaxing at a cabin, exploring a national park, or simply enjoying some time away from your normal routine, this challenge allows you to participate wherever life takes you. How It Works Accumulate 250 minutes of running, walking, or hiking between July 410, 2026 Complete your minutes over as many activities as you'd like Track both your total time and total mileage Submit your final totals at the end of the challenge Receive your digital finisher certificate Eligible Activities Running Walking Hiking Trail Running Treadmill Walking or Running Participant Perks check mark Digital Race Bib check mark Digital Finisher Certificate check mark Official Finisher Listing check mark Social Media Finisher Badge check mark Optional commemorative apparel available for purchase

The 250K Team Challenge invites teams to collectively cover 250 kilometers (155.3 miles) during event week in honor of America's 250th anniversary. Whether you're a running club, hiking group, tennis team, workplace, family, or a group of friends looking for a shared goal, this challenge is an opportunity to work together toward a common finish line. Every mile counts. Every teammate contributes. How It Works Form a team Accumulate a combined total of 250 kilometers (155.3 miles) Complete your miles between July 410, 2026 Running, walking, hiking, and treadmill activities are permitted Team members may participate from different locations Submit your activities throughout the week and watch your team's progress grow on the leaderboard Team Leaderboard RunSignup will track team mileage throughout the event, allowing participants to follow their team's progress in real time. Will your team reach 250K? Will you be the first? Will you go beyond the goal? The leaderboard will tell the story. There are no requirements for how your team divides the distance. Some teams may spread the mileage evenly. Others may rely on a few highly motivated members to carry a larger share of the load. However your team gets there, the goal is the same: 250 kilometers. One team. One mission.
