DS is thinking of applying to Oxford so we went for a visit a few days ago. If he was to go there he would be travelling regularly between his college (tbc), the maths department, the Iffley Rd Sports Centre and the Cutteslowe/Sunneymead area (north Oxford) where he has a friend/sport.
We covered the area on foot and (to north Ox) car. It doesn't look very cycle friendly - but maybe there are back roads? And presumably in term time there would be many more cyclists than we saw on our visit? I'm looking for some reassurance!
Also, are the buses subsidised for students? Are they regular enough to just turn up at a stop and hop on a bus within a few minutes?
