100 Miles, 4-Day Stage

Yosemite is the newest addition to our multi-day running adventure catalog. After years in the planning state, this trip is now a reality. DON'T hesitate to sign up for this one. 


Yosemite needs no introduction. Her iconic and immense towers of glacially cut granite shock the mind and senses mind into awe and humility. While thousands of visitors flock to the National Park each year, few migrate far from the main valley floor.  We'll end up there too, but only after running over a 100 miles of wilderness trails. This run will summit both El Capitan and North Dome, flow with the river down the Grand Canyon of the Tuolumne, traverse the Tuolumne Backcountry, and explore a majestic landscape of mountain meadows, granite peaks, and pristine alpine lakes. 

Course Overview

Tuesday, Day 1: Meet in Yosemite

We will meet runners at 4pm at the Crane Flat Campground. If there is sufficient demand, Aspire will operate a shuttle from the San Francisco airport to the park. That evening we will serve dinner and go over routes, risk management, and gear in preparation for the run.

Wednesday, Day 2: Tamarack Flat to Porcupine Flat, 22 Miles, Elevation Gain: 5967' Loss: 4236'

This run starts right from camp. After an early breakfast, runners will head east following the north rim of the valley before summiting El Cap and North Dome. Here the trail turns due north along Indian Ridge and up the headwaters of Snow Creek. The final miles of trail bring runners directly into Porcupine Flat campground and the awaiting food, drinks, showers, and relaxation. This location will serve as a base camp for 3 nights.

Thursday, Day 3: Grand Canyon of the Tuolumne River, 28 Miles, Elevation Gain: 4994' Loss: -5733'

After breakfast, it is a short shuttle from camp to Tuolumne Meadows and the trailhead that accesses the Tuolumne River Canyon. The first 20 miles of the day follow the descending river grade through a deep canyon of carved granite. This trail reveals a ribbon of pools, waterfalls, and granite formations that will beckon the trail weary runner to pause and swim. At the Pate Valley, the trail turns south following Piute Creek and climbing out of the canyon to the Wolf Creek Lodge. An Aspire shuttle will transport runners from the lodge back to the Porcupine Flat basecamp.

Friday, Day 4: Ten Lakes Basin, 23 Miles, Elevation Gain/Loss +6368' -5620'

A short shuttle gets runners to the Yosemite Creek trailhead. This run steadily climbs over 6 miles to Ten Lakes Pass. From this high point, the trail wanders through a spectacular landscape of alpine granite, meadows, and lakes. Circling around the north face of Tuolumne Peak, the trail skirts the Potty Dome Lakes and May Lake, finishing at Snow Flat. Here again the shuttle brings runners back into Porcupine Flat.

Saturday, Day 5: Tuolumne Meadows to Yosemite Valley, 28 Miles, Elevation Gain/Loss +6368' -5620'

The final day of the trip brings runners out of the Tuolumne high country and into the splendor of the Yosemite Valley. Following sections of the John Muir Trail, crossing over Tuolumne Pass and Vogelsang Pass, and spending many blissful trail miles through alpine splendor. The trail follows Fletcher Creek into Merced Lake and parallels the Merced River through Little Yosemite Valley before the final finish at Glacier Point and the Yosemite Valley. Here runners will be greeted with a final celebratory meal.


This trip begins and ends at Crane Flat inside of Yosemite National Park. All inter-trail shuttles will be provided by Aspire. We also plan to provide a shuttle to and from the San Francisco airport on Tuesday and Sunday mornings, this shuttle is NOT included in the course fee. All those booking flights from San Fransisco should plan to fly home on Sunday afternoon after 4 pm. Runners driving personal vehicles to the start may leave leave them at the Crane Flat Campground.


The accommodations for this trip will be "front country" car camping. The first night will be at Tamarack Flat Campground and Nights 2-4 will be staged out of a basecamp at Porcupine Flat with a final optional night at Crane Flat Campground on Sunday.  Aspire will provide lively camp amenities for a remote but comfortable “glamp” style experience. Runners will need to provide or rent a personal tent, sleeping bag, pad, etc.
