Diablo Trail Run routes

Get out for a stunning run up Mount Diablo this August. This is the perfect way to round out your summer and enjoy the beautiful views of the Bay Area and Mitchell Canyon.

If you are looking for an easier route with less hill climbing then perhaps the 4 miler is for you, but if you are looking for a bit more of a challenge then consider signing up for the half marathon (or even the 50K).

Terrain: The course takes place largely on a dirt road up the side of the mountain, there will be portions of this race that will be on single track.

Elevation Gain: The 4 and 10 mile races will have between 400 - 2,400 feet of elevation gain, whilst the longer runs will range from 3,420 - 7,990 feet of elevation gain. These hills are not to be scoffed at so you better include some hill training in your schedule.

Frequently Asked Questions

Do I need to bring my own cup to the Diablo run?
Yes, in an effort to protect the environment runners are asked to bring their own drinking bottles and cups that can be filled up at the aid stations.
How hilly is the Diablo run?
If you are doing the 4 mile run then course is fairly flat, but if you are tackling one of the longer trails then it can be quite a hilly course and you should make sure you've got some hill training in before taking it on.
Is there a time cut-off for the Diablo run?
Yes, there is a 9 hour limit for the Marathon and 50K races, so runners should make sure they are on track for completing this time.
