My name is Liz Derstine, trail name “Mercury”. I’m a distance runner, endurance hiker, and musician residing in Boston, MA. I co-founded the Portland-based running team Rose City Track Club and coach high school and individual runners. I am a classical pianist, songwriter/composer, and have toured nationally and internationally as a pop keyboardist and singer. I’m currently pursuing a Master of Music at Longy School of Music of Bard College.

I began running at the age of 14, then as an adult became immersed in track and road racing with personal records of 36:44 in the 10K, 1:22:43 in the half marathon, and 2:51:34 in the marathon. In December 2019, I ran my first ultramarathon, placing 4th in the Hellgate 100K. In the summer of 2020, I set the women’s supported fastest known time northbound on the 2,193 mile Appalachian Trail. In the spring of 2022 I placed 1st in the Hagg Mud 50K and broke the women’s self-supported fastest known time on the 348.6 mile Pinhoti Trail. This summer I broke the women’s self-supported fastest known time on the oldest long distance trail in the US, the Long Trail!

Outside of running and music, I love hanging out with my cats Bo and Juno, seeking out delicious bagels and pastries wherever I go, and indulging in whatever is the latest in the sci-fi/fantasy pop culture realm.

I write weekly stories on my newsletter “Mercury on the Run”, which you can subscribe to here. You can also find me on Instagram, Facebook, and Twitter.
