Summary: Starting in Sausalito near the Marin Headlands and ending in Crissy Field in San Francisco, runners will run several ascents and descents, much of which offers beautiful views of San Francisco and Marin, including the Golden Gate Bridge. Once runners leave the Marin Headlands, they run over the Golden Gate Bridge itself before the final push to finish at Crissy Field. This was a new course in 2017 for both distances, so this will be the second year running this course.

Lessons Learned from Race Reports

  • Start and Finish are in a different location. Make sure you know the shuttle information
  • For the 50k, total distance is 32.4, so you have your longest stretch between aid stations after the last aid station at 26.4
  • Since there are several races of varying distances and courses going on over the weekend, be sure you know the ribbon course marking color that corresponds to your race
  • If it’s rainy, sections of the trail are very exposed and can make for some wet, windswept miles
  • With the 50 miler starting earlier, if the trail is wet or muddy, it can be quite sloppy by the time 50k runners are going through
  • Again, if it’s muddy, the descents can feel all the more steep because they are slicker and have less traction
  • Be prepared for any kind of weather, especially if you’re flying to the race, as it’s been drastically each past year of racing, and a lot of the course is exposed
  • With so many climbs and descents, one after the other, pacing is a must, as the climbs will seem harder and harder, and be sure not to burn out on the initial descents and flats
  • For the 50m, headlamps are required at the start and then 1 hour after sunrise
  • Course can get a bit crowded by the second half of the day with 50 milers, 50k runners, and marathoners all out on the course
  • Train with technical downhill trails
  • 50m: *Very* steep stairs coming out of the Stinson Beach AS, on the Dipsea Trail. Prepare to power-hike.
  • 50m: One deep creek crossing at about mile 37 – no avoiding getting your shoes wet!
  • 50m: Several branches/trees to go over or under especially on the long downhill to the Stinson Beach AS (from Cardiac AS) and on the technical section between Cardiac and Old Inn.
  • The tourist sidewalk was open to the public over the Golden Gate Bridge, so you really need to pay attention to the wandering groups of walkers. After the bridge, there a few more flights of downhill stairs to get to Crissy Field.
