Invited by the king of Bhutan, CU Boulder PhD student Clare Gallagher completed the 109-mile Snowman Race to bring attention to the realities of climate change


Usually when Clare Gallagher runs 100 miles, she does it all at onceā€”a day thatā€™s alternately punishing and exhilarating and at the furthest boundaries of what her body can do.

The 109-mile was different. It spanned five days across the Himalayas and saw 16 of the most elite ultramarathoners from around the world traversing multiple mountain passes approaching 18,000 feet.

ā€œAs far as ultramarathons go, it was not that crazy a distanceā€”we were doing about a marathon a day,ā€ Gallagher explains. ā€œBut it took so, so long because these mountains are just so high. We started in Laya (Bhutan), which is about 13,000 feet in elevation, and went up from there.ā€

Gallagher, a PhD student in the Ā鶹ŹÓʵ Department of Environmental Studies and the Institute of Arctic and Alpine Research (INSTAAR), was invited by the king of Bhutan to participate in the 2024 Snowman Race held at the end of October. It was the second time the race was heldā€”an event envisioned by Bhutanese King Jigme Khesar Namgyel Wangchuck to draw international attention to the stark realities of climate change in Bhutan and around the globe.

ā€œOnce we actually got there and were literally on top of these glaciers, I could see his point,ā€ Gallagher says. ā€œHis goal is for international trail runners like myself to help share the story of what we saw, and what I saw is that the glaciers are melting.ā€

Running 100 miles

Before she vividly learned that a journey of 100 miles begins with a single step, however, Gallagher was simply a girl who liked to run. She ran track as an undergraduate at Princeton and kept running in Thailand, where she moved after graduating to teach English. While there, she signed up for the inaugural Thailand Ultramarathon almost on a whim and ended up winning.

The races she entered grew in length, and in 2016, at age 24, she ran the Leadville Trail 100 for the first time and won. ā€œI had been reading Outside magazine, and I always looked up to some of the women who preceded me (in ultramarathons),ā€ Gallagher says.

ā€œI thought they were really badass, and trail running seemed a lot more interesting than trackā€”Iā€™d gotten really burned out in undergrad, but to race in a beautiful mountain environment, in places that are so remote, really appealed to me.ā€

She won the 2017 , setting a course record, and the 100-mile Western States Endurance Run in 2019, the Black Canyon 100K in 2022 and the Leadville 100 again, also in 2022. She was invited to run the inaugural Snowman Race in Bhutan that year, but sheā€™d started her PhD program, and her schedule couldnā€™t accommodate the training.

When she was invited to the second Snowman Race in 2024, despite still being in graduate school, she eagerly accepted. The 16 participants were evenly split between Bhutanese and international runners, ā€œand the Bhutanese runners destroyed us,ā€ Gallagher says with a laugh.

ā€œThe physiology of running at altitude is pretty fascinating. A lot of the literature is finding that aspects of this ability are genetic, so if you donā€™t live at these altitudes and if you canā€™t afford to be acclimating for a month, your experience is going to be really different. Itā€™s probably the gnarliest race Iā€™ve ever done, and I got wrecked by altitude. People thought I might do well because Iā€™m from Coloradoā€”and I was using an altitude tent beforehand a little bit, but I was also taking my PhD prelims and didnā€™t want to be sleeping in it. So, I got destroyed.ā€

She did, most importantly, finish the race, and the slower pace she adopted in acquiescence to the altitude allowed her more time to look around.

The Snowman Race course follows the historic, high-altitude Snowman Trek route, beginning in Laya and ending in Chamkhar, and summitting a series of Himalayan passesā€”the highest of which is 17,946 feet.

ā€œOn day three we were up almost to 18,000 feet, and Iā€™m walking and kind of sick with altitude, but I still had never felt the immensity of what I felt in the Himalayas,ā€ Gallagher says. ā€œThe race route goes really close to glaciers well over 18,000 feet, and Iā€™ve honestly never felt so scared. I could tell these glaciers were melting and the sun was so hot.

ā€œThe story of Bhutan is that these glaciers are melting at a much faster rate than predicted and are then creating these big alpine lakes that break through their levy walls or moraines and flood villages. We ran through one of these most at-risk villagesā€”it takes seven days to get there by horseā€”and the people who live there donā€™t want to be forced to move. So, they were saying, ā€˜Please send our message back to your countries, weā€™re scared of our glaciers obliterating us.ā€™ā€

And even though her PhD research focuses on plastic pollution in oceans, ā€œeven the issue of plastic pollution was apparent up there,ā€ Gallagher says. ā€œThe interconnectedness of our world became so, so apparent up there. A piece of plastic trash up there is going to degrade really fast because of the high altitude and super harsh alpine environment, and then all those chemicals are going to go downstream. Thereā€™s not ton of trash in Bhutan, but plastic pollution is still a part of this story.ā€

She adds that Bhutan, like many smaller nations, is vulnerable to the impacts of climate change despite having one of the smallest carbon footprints on the planet, and she rues that it takes runners from western nations flying thereā€”another carbon-intensive activityā€”to draw attention to the seriousness of climate change.

ā€œA really surprising take-home from this journey was how spiritual the experience was,ā€ Gallagher says. ā€œAll of my fellow Bhutanese runners were praying at mountain passes, and any time there was a meditative stupa, they were stopping and praying to the mountain deities, thanking them for safe passage.

ā€œI really do feel thereā€™s some connection between caring for this planet and each other and all the plants and animals on this planet. I feel like that reverence is something Iā€™ve been missing in my work as an environmentalist. The phrase ā€˜climate changeā€™ has taken on an almost corporate flavor, but in Bhutan things arenā€™t emails or PowerPoints or slogans, theyā€™re real. Climate change is not just a phrase; it means melting glaciers. So, Iā€™m interested in taking that depth and reverence for the land and living things and beings and asking, ā€˜OK, what are our problems here in Colorado? What are our challenges?ā€™ā€

A hazard of the field in which sheā€™s immersed is extreme climate anxiety, and Gallagher says sheā€™s worked to focus day-to-day on ā€œtaking care of what I can take care of and acknowledging my present. My experiences in Bhutan reminded me that I also feel a lot of hope and a lot of motivation to do what I can do, and smile while Iā€™m at it. I feel a lot of gratitude for being alive at this time in history and asking, ā€˜What are we going to do with this moment?ā€™ā€
