East Bay Ridge North to South

I could only find Christian, crazy enough to come with me on this great journey. We went on a mainly unknown trail to us, starting from Richmond Wildcat Canyon, to Lake Chabot. It is a distance of 31mi and 6100ft of elevation gain. We started at 6am sharp and managed to finish it ahead of our schedule, at 4.30pm. 10.5h, and we where pretty happy about it. Next time I will bring the dogs, all is "Dog Friendly"!!!!!!
This is the trail we took.
