Where to go biking

Recently, there has been so much done for those of us who just can't live without being active and do stuff other than hanging around bars, watching movies, eating hamburgers and hotdogs...even on travels we need to burn some of our energy and take a break from sightseeing and all that goes with being a tourist/traveler/nomad... :)
How about biking in Prague? It's possible, too!!!! And the best part about it is that you can even combine the two - seeing sights and pedal :)
This bike path is one of my favorites, it stretches along the river. I prefer to leave the town behind at its best, but if there is not much time to do so, this trail is the one. The best is just before the sunset!!!! The sun is in your face (if you're headed from the downtown towards the end of the city), there are birds in the sky, people strolling around at a slow pace, there are some nice fish restaurants by the waterfront, you can take a boat ride, hop on a steamboat...I love my evenings spent there! Just give it a shot when you're around, too! It's memorable! And it again costs nothing!!! :)
Note: Also great for rollerblading/skating, running, walking, or just taking pictures :)
