Walking takes me 1 hour. Cycling 20 minutes. I finish the cycle breathing heavily. If I do it walking my heart rate barely notices it.
Biking there, back home and back to work again would probably burn more calories than walking in the same amount of time (depending on how much time you spend sitting at stop lights).
As noted, running will burn the most calories, but finding a longer route to bike will be more fun and burn more calories than walking.
