Last Monday I walked 30 miles.
Because I was on my own, I decided to opt for a hike through the bay area rather than in the hills so that I was both phone and car accessible if I ran into any trouble. This made the route rather flat, so it was much easier than previous hikes and I was able to keep around an 3.8 mph pace. I was still pretty drained by the end though.
I headed from our house to Stanford with a quick stop at Google for lunch with my brother. Through a lot of Google Maps tweaking I was able to keep my route mostly on the various pedestrian/biking paths in the cities - San Tomas Aquino Creek Trail, the SF Bay Trail, 3 pedestrian bridges, Steven's Creek Trail, 2 Baylands Parks, and even a trail next to Sand Hill Road.
It was awesome.
