Silke’s Race Results

My passion for running started when, as a lightweight collegiate rower, I preferred to do my second workouts running on the dirt paths in St. Louis’ Forest Park than rowing on an erg in the windowless basement (can you blame me?!). I ran my first half-marathon in 2003 and a few years later I was toeing the starting line of the New York City marathon. But somewhere in between, while living in the Tetons, I fell in love with mountain running. I’ve pounded plenty of miles on the pavement but my heart sings on the rough ‘n rocky, beautiful trails. This sport has given me an immense sense of freedom and connection to the world around me — it’s allowed me to discover the most beautiful landscapes, create life-long friendships, and discover the possibilities within me.

I live in Boulder, CO where I co-founded the local running club, the Rocky Mountain Runners. I work full-time in the educational non-profit world. When I’m not running or working or chasing our toddler all over the place, you’ll find me making a mess in the kitchen, beekeeping in my backyard and embarking on overly ambitious DIY remodeling, carpentry & landscaping projects at my home.
