Trails will be marked with flagging and signs at major intersections. Participants are advised to review course maps and download GPX files for reassurance. This is a cupless race so runners must bring their own hydration system. Aid stations provide vegan friendly options, hydration, fruit, salty snacks, sandwiches, and assorted sweets.
