Hello Yellowstone-Teton Running with the Buffaloes racers!!

Until race day, most of the updates will be posted to our Facebook page, which is where you can also post/ask any questions about the event.

Important: If you have not already made your flight, hotel or car rental reservations, we suggest you do so very soon in order to secure the dates and best rates.  The race, which is point-to-point, starts in West Yellowstone, MT and finishes in Driggs, ID (and the host hotel is in Victor, ID).   Please check out the Lodging & Travel page for updates!


If you are running the 50 mile race it is best you work out a ride to get to the start and or have a crew. If you drive your car and leave it at the starting line you will need to find a ride back to the starting line to retrieve your vehicle. We suggest adding a post to the YT race Facebook page that you are looking for a ride to the 50 Mile start; many people will be driving there so carpooling should not be an issue..


The weather is 100% unpredictable.  Apart from normal race clothing, running shoes and reflective/safety gear, be sure to pack a wind/water proof jacket, tights, lightweight hat, gloves, etc., and plan on having a change of clothing incase the weather isn’t ideal.  Additionally, plan on bringing your own foot care kit, pain meds (we do not distribute pain meds during the event) and/or any other supplies you typically use during a long race. The views should be outstanding so don’t forget to pack a camera!


As a reminder, we encourage all participants to carry Bear Spray from mile 50 to the finish line.  Bear spray can be purchased at our Teton Running Company store, where you will pick up your race packet. Additionally, reflective gear and blinking lights are mandatory pieces of gear.  You may also enjoy a one-time 20% discount off all shoes, clothing and nutritional products. Place your order in advance and we can have it ready for you upon arrival, or with a purchase of $50 or more we ship to you free!  Please email to place your order, or visit to order on-line.

Crew access can be often and is easy access!
