Starting from Oxford town centre, go east to Magdalen roundabout (on `the plain'), take the main right fork to Iffley Road, then the path to the gym is about 400 metres away on the Right hand side of the road. If you're coming by car. you need to take the exit after that (Jackdaw Lane) which is just past the running track/rugby ground.

Note that there is a combination-key lock on the first gate (which is locked at unpredictable times). The gym staff will give out the code, however the first time you visit the gym you may need to get in via the farther Jackdaw Lane entrance (unless you can find out the code from a friend).
