PR Coaches


Coach Ross Martinson

  • Background: I started running cross country high school freshman back in the 90s and I have no idea what made me get started but I am glad I did! I found I loved racing, and it took a few years but I eventually formed a good relationship with training as well.
  • Running experience: After running at Haverford High School and St Joseph’s University I competed into my 30s placing in the top 5 at Broad Street 3 times as well as a top 25 finish at the Boston Marathon.
  • Favorite distance or race: Ten miles is my favorite race distance. Long enough to require some serious training, but short enough you don’t have to worry too much about what to eat or being sore the next day.
  • Reason for coaching: I found myself making schedules for myself and other runners in my group and just sort of fell into coaching There is something really fantastic seeing people reach for their running goals, and then realizing after a few years they have become a lifelong runner. Coaches have had such a positive influence on my life and I hope I can pass that on.
  • Personal mantra: Smile and push on.

After college, I went on to win a bronze medal and help USA secure a win at the 2011 North American Central American Caribbean Cross Country Championships and helped the All-Ivy team finish 8th at the 2011 Izumo Ekiden.  Afterwards I competed for several years as part of a post collegiate training group in Syracuse where I finished top 20 at several USA Road Championship Events. I was then offered a scholarship to the University of East London for graduate school where I pursued a MS in Strength & Conditioning while competing for the University, running for the Newham Essex Beagles and Run-Fast Sports Management team. After a competing abroad (and training in Kenya), I returned to the states to train for my first marathon. In my debut marathon, I finished 8th overall, 3rd American in the 2017 Houston Marathon with a time of 2:18:16.  
  • Favorite distance or race: Favorite track distance would be the 5,000m, favorite road distance is the marathon.  My favorite track race is the Penn Relays because of the environment, for the road is the Izumo Eiken because it is a relay road race and for the grass it is the Britsh Cross Country Nationals because of the mud.
  • Reason for coaching: I have been very fortunate to work with some great coaches during my running career. As one coach told me, you owe it to those who helped get you get to where are to stay involved in the sport and pass along their knowledge to others.
