The Coloma River Run is a 5K, 10K and 10-mile race that starts in the Magnolia Parking Lot across from Hart to Hart Winery. All three races start at 8 AM and head West for about a quarter of a mile. The 5K turns left and follows the Gerely Loop with glimpses of the South Fork before it wraps back around to the finish line. While the 10K and 10Mile races head up the connector trail after crossing two small creeks. After climbing the connector trail the race hits the down and up, both distances ascend the down and up a trail with a 22% grade. These distances are mapped out on a beautiful but challenging course. After taking several trails with views of the river the runners wrap around Cronan Ranch and come back onto the connector trail to the finish line.
