The Bizz Johnson is a scenic trail running event held in Susanville, California, featuring distances of 50K, marathon, half marathon, 10K, and an Express Half Marathon with a relay option. The USATF-certified marathon course is a fast, mostly downhill route along the historic Bizz Johnson Trail through Lassen National Forest, with a net elevation loss of 929 feet. Runners experience a climb early on, followed by a 1,300-foot descent over 20 miles, passing through the Susan River Canyon with picturesque wooden railroad bridges and two former railroad tunnels near the finish. The event offers a Boston Marathon qualifier and a cupless race format to reduce waste. Visit the organization's website for the most recent information.
