Comfortable temps, big temp swing

Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 77°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

The Half Marathon runs the Bothe-Napa Valley State Park loop twice on dirt singletrack, about five miles north of St. Helena. From the picnic area it heads west on Redwood Creek Trail, climbs the Coyote Peak Trail, drops through the South Fork and Spring trails, and returns by the Vineyard Trail past the Ritchey Creek campground. Creek crossings, rocks and steady hills make it a slower half than on the road, and the second lap covers the same ground as the first.
