This COVID season has taken away many of the big race goals that you and your friends may have had. C3 has the luxury and privilege of their own C3 quarry for safe swim and beautiful local country roads and trails to bike and run on. We know that goals give you a purpose to get out the door each day. With some people not able to travel to the USA for long distance races in 2020, or races being cancelled, C3 and former Olympic Coach Barrie Shepley have decided to give 99 lucky people a focused goal and purpose. Don’t delay, the C3 Old School Long Course Triathlon is a great way to end a very odd summer.
