So for the past couple of weeks I have basically been using the route Stephen suggested, which has mostly been great. However, even though I'm going to keep using that route in the morning for now, I'm thinking about finding a different route back for a couple of reasons:
1) Ellsworth is totally fine inbound, but the right half of the outbound lane is pretty gross. Taking the lane helps, but I'm not always comfortable maintaining that approach when there's heavier traffic, and riding on the right means risking hitting some nasty bits of road and finding myself non-upright. (I imagine a lot of people could handle it fine, but with my marginal riding skills and the giant book-and-laptop-filled panniers I'm lugging around, I'm not quite nimble enough to handle that situation safely)
2) Especially on the days when I have night class and am coming back welllll after sunset, when traffic is less of an issue, I'd rather find a way back that takes better-lit, larger roads and skips the trails.
I'm trying to decipher the other options here and see which one is best going outbound. Thoughts?
By the way, thanks for all the help! I've investigated these other route suggestions too, and they've all been useful in helping me figure out which roads to take to get to various places between here and Oakland.
And @Mick (re: running): That book does sound interesting. Part of this is that I was genetically endowed with some nasty over-pronation that all the fancy shoes and form correction in the world couldn't fix, plus I don't exactly have the ideal lightweight body type of a distance runner, so even under ideal conditions, I'm more prone than most people to weird stress injuries. But switching to running exclusively in Brooks motion control shoes made it possible for me to run at all, and changing the way I train (more cross-training, verryyy gradual distance increases, not ignoring pain like I used to) has kept me injury-free for a while, knock on wood - and I will try to check out that book to see what other changes it would recommend. And, like you said, it is awesome to be so close to Frick Park - less bad pain since I'm not running on concrete, more good pain since I have lots of different hills to run up!
