Comfortable temps, warming through the race

Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 67°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

About the Bizz Johnson Trail Express Half Marathon

The Express Half Marathon covers the second half of the Bizz Johnson Trail Marathon route. It starts at Goumaz Campground, takes a short up-and-back, and then drops down the Bizz Johnson Trail along the Susan River to the finish at Hobo Camp in Susanville. The point-to-point course follows a former railroad grade, so the descent is steady and runnable, and it includes the wooden railroad bridges and the two old railroad tunnels in the Susan River Canyon.
