Fun route! I started in Richmond, getting several less-exciting miles out of the way early, enjoyed everything else about the journey, and finished in the quietest version of San Francisco I've ever seen. I would have liked to use BART for the start/finish (nice course design) but I'm trying to stay off public transit unless truly necessary these days, so John dropped me off and met me at the other end.
Love the views of Mount Tam from the Richmond bridge (and several other locations). Good link-ups of bike paths. Nice little climb in the middle. Sausalito looks like a place we need to go back and visit for real sometime. And of course, the iconic Golden Gate Bridge plus running around the edge of San Fran, always special.
I made plans to resupply at a couple stores, but I found all water fountains to be running (yay!) and carried plenty of snacks so I didn't actually need to stop.
I made a couple minor tweaks to the previous run tracks, mostly picking the best of the set for each spot that wasn't completely obvious. There's a bike route that avoids I-580 completely; that's the biggest suggestion I would make.
I will go into more detail in my blog post for reference for future runners. I do recommend that there be future runners, it was quite a lovely day.
Now someone should create a "3 Bridges" loop that includes Dumbarton... just throwing that out there. You're welcome.
