I haven't been bike commuting lately due to being off of school for the summer. I have been riding a bus to my job at summer camp

Today, I rode my bike the four miles uphill to the bus stop.

I was amazed how much stronger I was. I spend five weeks with the summer campers riding a single speed bike as a mountain bike and powering my way up hills with brute force. Even just a couple of weeks riding like that made a real difference in my speed and power.
