  Welcome to the 14th annual FTBT-Herron Half Marathon/10k/5k and Kids' Race! Please see the main webpage (Herron Half/10k/5k) for details, but here a few key points to know:

  PLEASE CARPOOL! We are limited in parking. We will have a team of people helping to make parking as efficient as possible, but we need your help by sharing rides.

  Official start times: 7:00 a.m. for the Half Marathon, 7:15 for the 10k and 7:30 for the 5k. There will be brief pre-race meetings 10 minutes before each start.

  These races are our largest annual fundraisers. We’ve kept registration fees low over the last 12 years to keep the events affordable. PLEASE CONSIDER DONATING TO SUPPORT OUR MISSION! The money raised from the races goes directly to building and maintaining trails in the 40+ mile FTBT system. In addition to event fees, our trails thrive largely in part to our dedicated sponsors. Please see the main webpage (Herron Half/10k/5k) for the list of this year's sponsors.

  The Flathead Race Series!

  See main website for details. Races include FTBT races, the Big Mountain Run, the Whitefish Trail Blazer races, and the Le Grizz races. At the end of the year, Competitive Timing will compile a list of all who have completed the series as well as a leader board.
