South Mountain Classic 20K/10K/5K

For the first time the South Mountain Classic was held in October – three different races, including a 20K, a 10K, and a 5K, along with the annual ARR board elections.

It was perfect day for running, with the terrific views we’ve all come to expect from South Mountain. The 20K started at 6:30 a.m., with the 10K following 30 minutes later and the 5K at 7:10 a.m. There was a free visor for members along with the free race entry, and plenty of refreshments before and after the start.

Top male finishers for the 20K were Aron Orar, Paul Kramer, and Adam Danks. Top female finishers for the 20K were Katherine Nierva, Victoria Espinoza, and Tressa Farnam. Top for the 10K were Frode Sundal, Stephen Kelly, and Joe McDonald for the men and Beth Siwek, Carol Duell and Deborah Eves for the women. In the 5K it was Chad Joyce, Warren Nastivar, and Mark Shields for the men and Debbie Leedy, Leah Gunter, and Monika Kennedy for the women (see all results). A big shout out to our volunteers, and we hope to see everyone at the Thanksgiving Day Classic on November 23!
