It’s quirky, hard-to-follow, and probably just a bit out of date, but it was the definitive guide to Pittsburgh road rides. With 425 rides it’s on the edge of overwhelming. Swan’s habit of referring to directions from other named rides, which themselves refer to still other rides make it a rabbit hole kind of thing.
Great book if you are looking for longer Sunday rides. Only a very few would be in the 25 miles or under range.
There was a book that had a few excellent shorter rides by Lou Fineberg (who used to post here), called “3 rivers on 2 wheels.” I imagine there are a few copies around. from 2002.
I’m thinking there really should be some newer book like these two and I don’t know about it because I’m out of touch. If not, maybe I should write one.
Hopefully a few of those will provide what you’re looking for. If you’re using RWGPS, they have a nice ‘Find’ function where you can put in a starting location, set your desired min & max distance (and min & max climbing), and then look at all routes that match your criteria. I recently moved away from Pittsburgh and that feature has helped me discover some nice rides in my new city.
