    About the Race

    Common questions

    How hard is the Merus Marathon & Ultra Marathon?

    We don't have a verified elevation profile yet — check the organizer's course map for the climb breakdown.

    What should I wear?

    Dress for ~10°F warmer than the standing temperature once you start running. Throwaway long-sleeve at the start, gloves and a hat for sub-50°F mornings, singlet plus visor when it climbs above 60°F. The race-day forecast above is the source of truth closer to the date.

    When does it sell out?

    No published deadline. Most races raise the entry fee in tiers and can sell out without warning — sign up early if you're committed.
