Bitterroot Runoff Trail Runs| 5 & 10 Mile | April 14th, 2019

The Bitterroot Runoff Trail Runs are held on beautiful single track trails in the hills above Lolo, MT. There are two options – a 9.7 mile course and 5.2 mile course with a scrumptious post-race brunch at the finish line for racers. Come join us to kick off the beginning of trail running season in Montana!

This event is the first race in the 2019 Runner’s Edge Trail Race Series.


New for 2019!

The Bitterroot Runoff is going cupless! Last year Runner’s Edge Events used over 20,000 cups. In order to cut down on waste we are moving all of our races to cupless events.

What this means for you– Please plan on carrying a bottle, bladder, or collapsible cup for use at the aid stations. If you would like to take advantage of the water, coffee, recovery drinks, or any other fluids we may have in the start/finish area, please plan on bringing a personal cup to use.

Thank you for helping us reduce waste at our events!
