  • Qualify for Boston with the flat, fast course!

  • Fun race - this is a dress-up marathon! Not only is the race over Halloween weekend, but our theme is also Wizard of Oz

  • Run for charity! All proceeds from our race benefit the Multiple Myeloma Research foundation as well as local charities

  • We have flattened out our course for 2018, now with only 300 feet of gain on the entire marathon course

  • The steepest climbs are the footbridges crossing the Boise River!


  • Early Bird until Dec 31: $45

  • Jan 1 - Sept 30: $105
