I’ve been a runner for most of my life in some shape or form. Whether it was running various road races or running after the ice cream truck. After moving to the San Francisco Bay Area in 2008, I was peer pressured into running the infamous Quadruple Dipsea Ultramarathon. Ever since my first finish, I was hooked for life. Since then I’ve gone on to complete over 30 Ultramarthons of various distances from 50k to 100 miles.


  • 10 x finisher Quadruple Dipsea 28.4 miler
  • 5 x 100 Mile Finisher: 2019 Bighorn Wild & Scenic 100 mile run
  • 2017 Cascade Crest Classic 100 mile run
  • 2015 Angeles Crest 100 mile run
  • 2014 Tahoe Rim Trail 100 mile run
  • 2013 Headlands 100 mile run


I first got introduced to OS1st products after researching for remedies for shin splints. Once I put on the performance calf sleeves, I could run again with no pain. As an Ultrarunner, I’m putting high mileage into my lower limbs. After trying every calf sleeve under the sun, OS1st continues to perform and retain compression time and time again. I’m glad to have OS1st in my arsenal As I build up for running 100 miles.


“I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.”

― Frank Herbert, Dune "Litany Against Fear"

I’m attempting the 2021 Grand Slam of Ultrarunning, by running four of the oldest 100 mile trail runs in the United States all in one summer: Western States, Vermont, Leadville, and the Wasatch Front.
