Course
After two laps of the half marathon route on the Bay Area Ridge Trail, runners add the 5-mile orange loop. The course is close to 60 percent singletrack, and 50K runners must reach 13 miles in 3 hours 40 minutes.
Race-day weather
Spring on Skyline Boulevard can feel cool and breezy even when the valleys below are warm, so layers help.
About the race
The 50K is the longest race of the Horseshoe Lake trail day, starting with the marathon and 30K at 8 a.m. Runners should carry about 20 ounces of water, since aid stations sit 5 to 6.5 miles apart.
