Only 40 Spots Left for the 2025 Boston 2 Big Sur Challenge Presented by HOKA

Only the fittest (or craziest!) runners ever attempt back-to-back marathons…much less 6 days and 3,000 miles apart! The April 27, 2025 race will mark the 14th presentation of the Boston 2 Big Sur Challenge Presented by HOKA and we hope to welcome 400 of the world’s fittest athletes to participate in two of the world’s greatest marathons. The Boston Marathon is on Monday, April 21, 2025. This program is for runners who have qualified for and entered the 2025 Boston Marathon and want to run the Big Sur Marathon only 6 days later. HOKA is the official sponsor of Boston 2 Big Sur. All B2B participants will receive exclusive gear and other unique, quality items. Click for Marathon Race Details
