Join 303 Dirt – the best experience at Valmont Bike Park for “kids” of all ages!
My 7 year old loves his lessons at 303Dirt! Gurion is an amazing rider and an inspiring coach. His wonderful rapport with kids, enthusiasm, and encouragement ensure that my son works hard, stays safe, and has fun!
I am an IMBA certified coach, with a passion for riding and coaching. Several years ago, I sold my business on the East Coast to move to Boulder with my family to enjoy the outdoors and the over 300 days of sunshine a year. Riding at Valmont bike park, I saw a lot of kids riding without safety gear, with the wrong bikes, and without the skills they needed to be safe. I started providing free skills clinics with my son to his friends and some of our neighbors. Soon after, 303Dirt was formed with the philosophy of small classes taught by experienced riders. Our goals are to provide an experience for kids that is fun, exciting and safe, and to build the foundation for a life-long passion for biking.
Myles Rockwell is a mountain biking legend. After years of pursuing his dream, he became the Downhill World Champion in 2000. He encountered numerous hurdles along the way, including breaking both legs in a motocross accident in 1997. His doctors believed he would never race again. Myles still loves to mountain bike today. He aims to give back to the community by offering his exceptional bike coaching skills and inspiring life story to positively influence the next generation. He is the president and co-founder of Rockwell Ridewell, a father of three, and a dedicated husband and mentor.
Miriam Van EK
Miriam is a big proponent of getting more ladies on bikes! She grew up in Colorado and recently graduated from University of Colorado Boulder. She rides for The Fix Bike Shop and her favorite styles of riding are dirt jumping and downhill. She is also a board member for the CheckIn Foundation, which aims to raise mental health awareness in the mountain biking community. When Miriam’s not riding her bike, she is probably hiking with her dog Aspen, or eating way too much dessert
Dylan started riding cross-country bikes when he was 19 but when he moved to Boulder in 2013 he quickly transitioned to riding dirt jumps almost exclusively. Now Dylan rides dirt jumps, downhill, trail, and BMX daily. Dylan has been a part of the Valmont Bike Park trail crew for four years. Dylan recently graduated from CU Boulder with a Geography degree. Dylan’s favorite thing on a bike is flowing dirt jumps and doing whips.
Gurion is a amazing rider and even better teacher! My two small groms have so much fun in his class and ride fundamentally better because of him.
