Second leg, 27 km: Flood & Grande Mountain Slugfest
Includes about.1 km of pavement. The rest is dirt trail with rocky and swampy sections, and approximately 6 km of hard packed dirt road.. Net elevation gain is 500 feet, but the total elevation change is well over 6000 feet. This leg of the race is characterized by long sustained climbing with about 3 km of very rough terrain and two creek crossings. The trail from the summit of Flood Mountain to the summit of Grande Mountain is the roughest piece of trail in the Death Race. The power line down the front of Grande Mountain leading back into town is the most dangerous part of the entire course. This is due to the steep, rocky drop-offs and unstable footing while running downhill. The Slugfest is the most technical section and is rated the second hardest leg of the Death Race (although many rate this leg as the hardest of all).
