The Coloma River Run consists of three courses, a 5K, 10K and 10-Mile. All start at the Magnolia Parking Lot across from Hart 2 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 of the American River before it wraps back around to the finish line. Both the 10K and 10Mile races head up the connector trail after crossing two small creeks. After climbing the connector trail both distances begin the elevation ascents and descents, with trails up to 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 on the connector trail to the finish line.
