Totally disagree having lived there for 6 months. Swimming facilities are great but cycling is terrible: the bike paths are poorly maintained (or at least they were when I was there) and you can't ride at speed, and the city is so sprawling that if you want to get out you either have to drive with your bike or ride for ages down some hideous main road. I used to go for a Sunday group ride with one of the main bike shops in the city and it consisted of riding out to an industrial estate or a housing estate in Fremantle and doing laps. Awful. Running is OK but you really have to do it in parks and because the weather is so terrible in summer (phenomenally hot) it's really hard to get a good run in. Add the astonishingly high cost of living (and that's from someone who lives in London), the widespread racism, the generally massive levels of parochialism and the really poor public transport and you really don't have a great place to live, plus there are only about 3 races a year.

I didn't like Perth much, in case you can't tell.
