The Inland Empire Running Club is comprised of everyday people just like you. Running is our passion and we truly embrace the opportunity to build friendships with the folks we run with. We believe you have to have fun and we put that above all else. Yes, we are serious about running, but we have adopted a family style atmosphere and draw off the energy and encouragement of each other. We welcome people of all physical abilities and once you experience the joy of what we do, you will wish you had started much sooner. The Inland Empire Running Club (IERC) of Chino Hills is non-profit organization created by veteran runners, walkers, coaches and people with a mission to advance the joy of the sports of running and walking in the Inland Empire of southern California. IERC is a year round marathon and distance training club specifically designed to meet the needs of all people regardless of their level of fitness.
