Bighorn Trail Run Update!

Spring in the Bighorns is putting on a SHOW! 🌸❄️
We’ve got fresh snow in the high country and wildflowers bursting with color down low — the contrast is unreal. 🌼🌲

❄️ Snow depth at Bald Mountain is currently 57 inches, and it’s melting steadily as spring storms roll through.
🛤️ Trail crews are still hard at work, and we’re continuing to scout key sections as conditions allow. Nothing significant to report yet, but stay on the lookout for updates!

No changes to our permits are expected  — and while we’re still planning on the original course, we haven’t seen every mile yet.

The mountains are waking up in a big way, and we can’t wait to welcome you to this year’s adventure! 🏔️💪 #BighornTrailRun

Bighorn 100M generously allows pacers from mile 30 (Sally's Footbridge) on the outbound. Pacers, please be considerate and carry your supplies including food and drinks. Bighorn Trail Run plans and provides supplies, food, and drinks for participants, but we do not plan for pacers as they are not entered in the event. We are proud we offer pacing earlier than most events to allow runners to have a pacer through the night, and we do not limit the number of pacers a participant can use while on course. Our aid stations are prepared for all participants entered, but not for pacers on course. Thanks for your understanding. 

Bighorn Trail Run is a "cupless" event. Each participant will be provided a reusable,  packable cup. It is required to carry a reusable cup/bottle for liquids at aid stations. Runners can choose to carry a bottle in lieu of the provided cup. Every participant must have a vessel to hold liquid at the start of the race. If you fail to carry a cup it's on you, we will not give you anything else at an aid station.  

Each runner will be allowed 1 crew member inside the Aid Station area/tent while inside at DRYFORK, SALLY'S FOOTBRIDGE, and JAWS. All CREW waiting must be done outside the Aid Station area/tent. CREWS please come prepared to wait in freezing temperatures at JAWS and SALLY'S.  Runners are allowed to be "CREWED" within 100 feet of the Aid Station.
