After getting multiple requests we finally put together a list of some of our favorite gravel routes in North County San Diego. These are all moderately difficult routes ranging from about 40-50 miles. Terrain is a mix of road, hardpack gravel, singletrack, bike path and fireroad. As such, we recommend a cross or gravel bike with tires at least 40mm in width. In most cases we’ve marked at least one water stop on course, and the dirt sections are labelled in blue. In general, these rides can take anywhere from 4-6 hours.
