These energetic action shots of my husband and assistant, Jon Kepko, a runner and triathlete turned model for a day, capture an important part of the San Francisco life: the running culture. Every Bay Area resident has at least one outdoor hobby (or is peer pressured into one) and has probably completed at least a 5K run if not a full marathon at least once. The current trend is the HALF MARATHON and the following series is the main training run through our beautiful city from the runners perspective.
