Weatherwise, I am also limited... small car*, the bike only fits without mudguards... fitting the guards takes 10 minutes at home, but it's a nightmare to do in the dark in a car park, so I can only really ride this with a benign forecast.
* Yes, I have heard of such things like trains, but none would get me to Oxford in time for the start and I am not going to pay money for overnight accomodation before AND after
