I actually run. I'm pretty sure the winner of this is going to be the bike.
Running's just too slow and I can avoid the bike music anyway by turning off the route/whatever and coming back most of the time.
well, it all depends on what bike you have/what gear its in. in GSC, they didnt have multi-mode bikes, so it doesnt count, but in RSE, you could choose your bike.Aside from flying, I run instead of biking. With the bike, I constantly run into things because my reaction time is just slower than the bike's speed. ;D Also, it is much easier and faster to stop and start running than on a bike.
