To get to the rides in Canterbury it is easiest to get the free shuttle bus between campuses. Its usually best to book it although not completely necessary, it just means if the bus is full there is no chance of you not getting on it. For the Wednesday ride it is best to get the 12:00 bus to Canterbury and to go home either the 16:00 or 17:00 buses are fine. For the 10:00 ride on Sunday the 9:00 bus is fine. Unfortunately, there are only buses every 2 hours on Sunday, so to get to the 13:30 ride you have to get the 11:00 bus, meaning you have to wait around in Canterbury for an hour or so.
If you’re bringing your bike along, when the bus arrives just check with the bus driver that it is okay to put the bike in the boot (the drivers have never said no), and then do so.
