This route tracks all the way down and back through the iconic Bitterroot Valley, starting in Missoula right at the beginning of the Bitterroot Trail. It is a dedicated paved trail the whole way. The trail ends in Hamilton. It travels the whole Bitterroot trail, with spectacular views of the snow-capped Bitterroot Mountains the whole way. You are encouraged to add on an extra 2.9 mile warm-up to make it an even 50, or 5.8 for an out & back 100! (The bonus miles don't count for the FKT, but you can include the your 50 or 100 mile time in your write-up.)
I'll be making an attempt at the FKT on 9/19, next Saturday. I'm going to do the out and back route, as well as a 3 mile warm up and cooldown to make it an even 100 miles. Conditions are looking good, it's nice and cool. I'll let you know how it goes!
Going to start at 2:45 tomorrow morning for the out and back, it should be a great day!
