Cycling in Brisbane Australia
I commute from the north of the city to the south every day, Lutwyche to Woolloongabba between 10 and 14 Kms depending on the route. 1/3rd of the trip is on bike paths, 2/3rds on roads or footpaths.
I can do almost all of the trip on the roads but its very risky at peak times. The trip takes around 40-45 minutes normally, around the same as a bus journey. If I risk life and limb it take around 30 minutes, same as the car in peak times.
In summary, the bike paths are great, I use them when I can even if they take a long way round,, footpaths safe but slow and roads fast but deadly.
