Pro tips

  1. 01

    Flat and Fast Pace

    The marathon course is flat, so settle into even pacing early instead of holding back for hills.

  2. 02

    Point-to-Point Logistics

    This course starts at Lucky Peak and runs into town, so arrange your ride to the start and your return from the finish before race morning.

  3. 03

    River and Bridges

    The route follows the Boise River just north of town, crossing bridges on tree-lined trails; use the water and bridges to break the race into segments.

  4. 04

    Cool Race-Day Temps

    Typical race-day temperature is 13.8°C, so plan a light layer you can shed once you warm up on the flat greenbelt.

  5. 05

    Half and Full Share the Route

    Both the marathon and half marathon begin at Lucky Peak and head into town, so half runners should prepare for the same flat, point-to-point river course.
