    Colorado Race Timing was such an amazing organization to work with. We work our events from out of state and Simon and his crew made getting the event ready a lot easier for us. It was nice not having to work about getting to the park early, marking the route and placing the volunteers. Colorado Race Timing did this all for us. Simon and his crew are very knowledgeable on how to setup and run a 5k and it was nice bouncing ideas off of them. We will definitely be using them for our race next year!

    Each year at the National Council for the Social Studies we sponsor a 5K run/walk for a local charity in order to give back to the community as part of our conference. Colorado Race Timing was our organizer for the 2010 5K run/walk. Colorado Race Timing provided all the supplies and promotions needed to make our race a success. They helped us connect to the local running community expanding our reach and opportunity to give back. Colorado Race Timing also brought our race to the next level with timing, bibs and all the things necessary to make the race successful and professional. I would highly recommend using Colorado Race Timing for any of your racing needs. I only wish we could use this team throughout the country!!
