About
Herron Half takes place on July 10, 2027, in Kalispell, Montana. Three distances are announced: 21 km (13 mi), 10 km (6.2 mi) and 5 km (3.1 mi), on high ground where forest and mountain meet, in the north-west of the state. Start times and elevation gain are not listed in our records.
Mountain half marathons run long in time even when the distance is honest: plan on carrying water and something to eat, which a road half never requires. July in the Flathead Valley is warm by mid-morning but rarely humid, so the first hour is usually the fastest part of the day — start early, start easy, and keep enough for the climbs in the second half.
