here is a Garmin link to the main trail run in Rancho Santa Fe, the “Ranch Run”. 11 miles of wood chip trail, rolling hills. There are a lot of variations to this trail, mostly depending on where you start from. This start is from the lower parking lot at San Dieguito Park. If you go about a half mile down the road, there is a trail head with some parking and starting from there makes it a 10 mile run and takes out the last hill to the finish of the 11 mile course. Word of caution if you run this loop, yield the right away to horseback riders. These are private trails and we are visitors there. If you come up on some riders, stop and let them pass. Then start running again after they have passed. https://connect.garmin.com/activity/726817638
