ERT is proud to announce it will be assuming the calendar of events from Robert and Linda Mathis.  As many of you are aware, Race Directors Robert and Linda Mathis were tragically killed on December 30th, 2011, when they were struck by an impaired driver while crossing a crosswalk in Lake Tahoe, Nevada.  Longtime pillars in the running community, Robert and Linda directed many well-known and long-standing events, such as the River City Marathon and Half, Lake of the Sky Trail Runs, Cool Moon 100M, and many others in northern California.

While we remain deeply saddened by this unexpected and painful loss to our community, ERT is happy to report that their races scheduled for 2012 will continue, and wishes to thank the Mathis Family and friends for placing their trust in ERT to honor Robert and Linda and continue their legacy.

Registration for the River City Marathon and Half has been reopened, and the remainder of the 2012 events will reopen soon.  If you have already registered, your entry will be transferred and you do not need to take any action.  Existing race websites will stay active, but news and information will also be located here, on ERT’s website.  Any questions or concerns regarding the events may be directed to Jimmy and Carmella at

Thank you for your patience, understanding, and support as we transition these races to new management.  Given the body of work Robert and Linda leave behind, the task is considerable, but rest assured that every effort is being made to meet the highest standards of service and experience that you have come to expect from not only Robert and Linda Mathis’ events, but from Elemental Running and Training.

We look forward to an exciting and successful 2012!
