O-Sho Trail Series
The O-Sho Trail Series is a three-race trail running series in Ogden, Utah, presented by the Trails Foundation of Northern Utah. The series takes place on the Bonneville Shoreline Trail and is organized as an evening community event with post-race food and refreshments encouraged.
The course begins at the TFNU 27th Street trail head, heads north to the Ogden Canyon overlook, includes a short lollipop loop, and returns to the 27th Street trail head along the Bonneville Shoreline Trail. A CalTopo map is available in event materials and a GPX file is noted as coming soon. There are no aid stations on course; runners must carry their own water and fuel. Water is available at the start and finish area.
