20 minutes on bicycle, more going home because I tend to be very tired.
Roughly the same time on buss, wintertime (it stops a lot on the way, and dont exactly go the shortest route).
When I was starting out ages ago, I rode the bus about 1 hour to training and just under 3 hours back (due to a badly planned bus schedule that left me waiting for a connecting bus for close to 2 hours. I REALLY hated that waiting room).
I should have moved sooner.
