Welcome to the 12th annual Herron Half! Please see the main webpage ( 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: 9:00 a.m. for the Half Marathon, 9:15 for the 10k and 9:30 for the 5k. There are 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 34-mile FTBT system. In addition to event fees, our trails thrive largely in part to our dedicated sponsors. Please see the main webpage ( for the list of this year's sponsors.


New for 2024! The Flathead Race Series!
Here's how it works:

Sign up and complete each of the following:

  • Herron 1/2 marathon
  • Foy's to Blacktail Trail Marathon
  • Whitefish Trail Blazer 50k
  • Le Grizz 50 mile race

All finishers of these 4 races will receive a $75 voucher to one of those races in 2025. 

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. We may get other sponsors to throw in a few other treats, too!
