That's awesome, Nas! When I got my bike out and commuted to work 8 miles, my legs were wobbly too. I rode every other day for the first couple of weeks. It does get easier. The overpasses/underpasses get easier as you build up muscle and endurance. 10 miles is nothing to sneeze at; it's a good ride. It's great to hear that you are enjoying cycling. It is addictive after a while. If I don't ride for 3-4 days, I get very antsy.
