The California Series Runner Challenge has been adopted by several races across California creating a really fun opportunity for all levels of
runners. This series allows athletes of all ages and competitive nature the opportunity to run for rewards. The great part about this is that there is no cost to run in the series. Each event participating in the series will proudly carry the series logo showing their affiliation and the
series will track the results of all runners. For details on how to participate in this series, or to learn about which events are participating, click here to be redirected straight to the series site.
