⏵ Course guide · Grand Targhee Resort, Alta, Wyoming
The Grand Targhee Wildflower Run puts a ridgeline 50K against a Peaked Mountain 22K and 10K through wildflower fields and aspen glades, all on the west slope of the Tetons at Grand Targhee Resort. I will walk you through the course and cutoff first, then give you a pacing and fueling plan built for high resort elevation. There are free calculators along the way to dial in your own numbers.
These facts come from the race's RunSignUp listing. The most recent posted date has already passed and the next date is not yet announced, so check grandtarghee.com before you commit.
The three main distances run on genuinely different terrain around the resort, so pick based on which day you want, not just how far you want to go.
The 50K runs on what the resort itself calls its "world-famous trails and high-elevation ridgelines," a genuine mountain ultra at ski resort elevation. Total elevation gain is not confirmed on either official page for this guide, so check the current course page for the up-to-date figure before you commit to a pacing target.
The 22K and 10K both climb Peaked Mountain, moving through wildflower fields and aspen glades with Teton views along the way. It is a different, more classically scenic day than the 50K's ridgeline route, still real mountain climbing but on a shorter, more approachable scale.
The Wildflower Run was back for its 4th year in 2026, run over Independence Day weekend with the 50K on Saturday and the 22K, 10K, and kids' 1K on Sunday. Entrant caps and prize details were not confirmed on a page fetched directly for this guide, so check the current race page for that information.
The one hard checkpoint published for the 50K is reaching the top of Dreamcatcher by 11:00 AM, so use that as an early pacing anchor even without a confirmed overall finish cutoff.
Ski resort elevation adds a real tax to your pace regardless of your fitness at sea level, so build in a conservative early effort on the 50K, particularly ahead of the Dreamcatcher checkpoint at 11:00 AM. Confirm the current course's total elevation gain before you finalize a target time.
⏵ Free tools to plan your effort
With aid station spacing not confirmed for this guide, plan conservatively and lean on your own carried nutrition.
Aim for roughly 60 to 90 grams of carbohydrate per hour and sodium in the 300 to 700 mg per liter range, adjusted upward for the extra hydration demand of resort elevation and a bright early-July alpine sun on exposed ridgeline sections. Carry a real reserve of your own calories given the unconfirmed aid station spacing.

⏵ Train for it with Summit Line
Get a training plan built around YOUR fitness and the kind of high-elevation climbing this ridgeline course demands. Summit Line reads your real training, builds the durability your distance asks for, and rehearses your fueling so race day is something you execute, not guess at.
The most recently scheduled edition ran July 4 to 5, 2026, over Independence Day weekend, and Grand Targhee has not yet published the next date. This is historically an early-July race, so plan on a similar Independence Day weekend, but confirm the exact date once it posts on grandtarghee.com.
The 50K runs Targhee's own high-elevation ridgeline trails, and neither official page I could confirm publishes a total elevation gain figure, so do not assume it is a mild resort loop. Ridgeline running at ski resort elevation means real climbing and real altitude to contend with, on top of whatever distance the course covers. Check the current course page for the up-to-date vert figure before you commit to a pacing plan.
RunSignUp publishes one specific 50K checkpoint: you need to reach the top of Dreamcatcher by 11:00 AM. That is an intermediate course point rather than a stated overall finish cutoff, so confirm with the current race page whether there is also a hard finish-line cutoff before you build your full pacing plan.
Both distances climb Peaked Mountain, moving through wildflower fields and aspen glades with views of the Teton Range. It is a genuinely different day than the 50K's ridgeline route, more of a classic high-alpine wildflower hike-run than a long ridge traverse.
The 50K is a serious high-elevation ridgeline effort at a ski resort, so it rewards runners already comfortable with mountain terrain and thinner air rather than a flat-course first-timer. The 22K and 10K are a gentler way to experience the same Peaked Mountain wildflower terrain and Teton views without the ridgeline commitment of the full 50K.
With no confirmed elevation figure or aid station spacing for the 50K, build a conservative fueling plan around your realistic time on feet at altitude rather than a tight cutoff. Aim for roughly 60 to 90 grams of carbohydrate per hour and sodium in the 300 to 700 mg per liter range, and account for the extra strain high resort elevation puts on hydration and pacing.
