This was the 50K national champs this year and I won my age group so I have to like the race. It is actually an amazingly scenic run in Marin County with parts that boarder the Pacific Ocean and others that go through redwood canyons. It is extremely hilly and almost the entire course is either up or down. The most extreme climb comes late in the race. The organization does a good job. The course is well marked. There are good and frequent enough aid stations. The finish line party is really fun.
