I thoroughly enjoyed San Marino via Rimini in fall 2023. I stayed one night on the Adriatic Sea in Rimini, had dinner in the old city center, took the bus the following day to San Marino, where I spent two nights. I did lots of walking, up and down, and found a very nice, small, family-owned Italian restaurant along the way. I ended up there for dinner for two nights. A very enjoyable part of the world. (I also fit Andorra in on the same trip.)
I also drove through Durres in 2021 and found a couple nice restaurants on the water; unfortunately I don't recall the name of those.
The race is very interesting!
