Meet the Run/Walk Coach!

Philip Dunn

Hello! I'm Coach Philip, the head coach for Team Challenge as we prepare for the awesome 2019 San Diego Rock N Roll Half-Marathon. I’m returning to Team Challenge after a two-year break to work as Head Cross Country running coach for San Diego Mesa Community College. I first started coaching with Team Challenge ten years ago for numerous Vegas, Napa and Kona seasons. I feel like I’m back home where I belong.

I've been coaching athletes of various skill levels for almost 30 years at training camps, retreats and fitness clinics around the country. My coaching focus is on running and walking for fun and fitness with a special interest in competitive racewalking (more on that later). Over the past ten years, I have coached hundreds of athletes across the half-marathon finish line. My proudest moment as a coach is sharing in the incredible joy that my athletes feel as they accomplish their goal of completing a half or full marathon. What a rush!

As an athlete, I raced all over the world representing Team USA (my other team!) at international racewalking competitions. My career highlights include racing in the red, white and blue at the Olympic Games in 2000, 2004 and 2008 and the Pan American Games in 1999, 2003 and 2007 in the 50km racewalk, an event in Track & Field. My personal best time for 50 kilometers is 3:56:13, about 7:35/mile pace... walking! I also love running, especially on the trails, so don't be surprised to see me helping out with both the runners and walkers this season. Gotta keep the team united behind one goal: finish that race!

Meet our Honored Hero!

My name is McKenna, I am 26 years old and I was diagnosed with Crohn’s Disease 10 years ago, shortly after my 16th birthday. I was heading into my sophomore year of high school as a promising varsity cross country and 800-meter track runner, a national-level Irish dancer and a straight-A student when my symptoms began. I went from having boundless energy, to dragging myself out of bed over the course of just a few weeks due to severe iron deficiency. My favorite foods caused me to be doubled over with abdominal pain. When my diagnosis came about six months later, I remember feeling like a huge weight was lifted, but my parents were devastated as my dad had recently undergone surgery for ulcerative colitis and they couldn’t imagine me going through the same.

 The remainder of my high school journey was a roller coaster of countless doctor’s visits and ineffective medications. I struggled with self-confidence issues that came along with weight loss and prednisone side effects. Through it I learned that I had friends who would stick by my side through the moon face and accidents. I learned that I could still finish a cross-country race - even if I didn’t finish first – and that I could still get into any college I wanted. Two years later, I found myself at University of California, Berkeley and despite a few bumps in the road, I graduated with a Bachelor of Arts in Political Economy in 2014, had the opportunity to work as an Endurance Manager for the Crohn’s & Colitis Foundation, and I am now working my way towards figuring out what I want to do long-term.

 Almost two years ago, I underwent a surgery to completely remove the lowest part of my large intestine, and am now adapting to a new lifestyle with a permanent colostomy bag, which has given me freedom and confidence back. Over the last 11 years, I’ve encountered it all – from adapting to new schedules, new medications, new diets, weight changes, other physical changes, changes in my outlook on life and my personality, mental health changes and struggles – it’s been quite a journey. But through it all, I’m grateful. It makes me who I am and I get to be part of this incredible community. I can’t express my gratitude in being your honoree this season. I can’t wait to share more of my story, and be beside you as you raise much needed funds and awareness of these diseases.
