ShadowChase Running Club

ShadowChase Running Club is a non-profit organization that promotes running and fitness related activities in the greater Modesto area.
Year after year we make a difference in the community through our club activities.

Our members represent a broad range of abilities. Some walk an occasional mile, a few are accomplished marathoners.
But most of us just like to get outside and run a leisurely pace.

Join the Modesto Marathon Training Program presented by ShadowChase.
