THE CHALLENGE

Only the fittest (or craziest!) runners ever attempt back-to-back marathons…much less six days and 3,000 miles apart! 2020 will mark the eleventh  presentation of the Boston 2 Big Sur Challenge and we will welcome 400 of the world’s fittest athletes to participate in two of the world’s greatest marathons. HOKA ONE ONE is the official sponsor of Boston 2 Big Sur. All B2B participants will receive exclusive gear and other unique, quality items.

REGISTRATION

Registration for the April 26, 2020 Boston 2 Big Sur Challenge is now open on a first-come, first-served basis. As of 10/11/19 at 11 AM, B2B is 80% full.

2020 entry fee: $399

  • To qualify for the challenge, you must also be an official entrant in the 2020 Boston Marathon. You can register for Boston either through your qualifying time, through one of their charity programs, or by invitation. B2B registration fees do not cover your Boston entry.
  • If you are already registered for the Big Sur Marathon by way of the random drawings conducted in July and August, you will still need to register for B2B separately. Once registered, email the registrar to have your original open registration voided and refunded. If you do not get into B2B, you can still run the Big Sur Marathon but without the B2B perks.
  • NOTE: If you are registered for B2B and Boston, but do not start or finish at Boston, you are no longer eligible for the B2B Challenge, medallion or finisher jacket.

Registration now open!
