Really, what could possibly be the bad side to winning stuff just for enjoying the summer sun? The 2012 I Bike PHL commuter challenge starts May 1st and carries on until August 31st (the unofficial boundaries of summer), and by participating, you can win free shit just for doing what you already do: Ride your bike. How it works is that you put a team together (up to 10 people per team) and download the app over here.
The app tracks your miles, CO2 emissions, calories, and more, and you use those stats to rack up points as a team. When you register, click the box to receive information from the bicycle coalition, and you will be entered to win into Philadelphia-specific prize raffles.
And really, why wouldn’t you want to win prizes just for enjoying the sun, summer, and trading your four-wheels for two. It’s a win-win-win-win. You can learn more about I Bike PHL here.
