Embark on an unprecedented adventure at the Welsh Festival of Running with our groundbreaking Pure24 challenge. This epic endurance race unfolds within the scenic Dare Valley Country Park, inviting runners to conquer five distinct distances—5k, 10k, half-marathon, and marathon—all within a strict 24-hour timeframe. The journey begins early in the morning at 7am with a brisk 5k run followed by another 10k stretch just an hour later. After a short break, participants tackle the formidable 50k distance starting at 10am. As dusk falls and night descends upon Dare Valley Country Park, runners face their most daunting challenge yet: completing both a half-marathon at 7pm and a full marathon by midnight. Each segment of this grueling course is meticulously timed to ensure participants maintain an average pace of approximately 3.5mph across the entire event. Finishing each leg ahead of schedule is crucial; missing any cutoff times will result in disqualification from the overall Pure24 challenge but not from individual race results. Supporting runners through their marathon efforts, organizers provide essential facilities such as a rest room equipped with hot and cold refreshments throughout the day. In the evening, pizza stations offer sustenance for those pushing themselves to new limits. Accommodation options are available both within Dare Valley Country Park and nearby towns like Aberdare, ensuring comfort between runs. For runners aiming to qualify for the 100 Marathon Club, separate entries for the standalone 50k and marathon distances allow participants to meet this prestigious requirement efficiently. Those who wish to have a support runner during longer stretches can contact organizers directly to receive a special discount code. Join us as we celebrate the inaugural Pure24 challenge—where every finisher will be remembered as part of history in making at the Welsh Festival of Running. Dare Valley Country Park invites you to experience this unique blend of endurance, scenic beauty, and community spirit. Are you ready for an unforgettable running adventure?
