One easy way we can all contribute to combating climate change in our everyday lives is replacing car trips with bike rides. Join the Great Climate Bike Challenge and commit to replacing one day worth of car trips each week with bike rides. That’s only four one-way rides! When nearly half of all trips taken in the U.S. are less than 3 miles (just a 15-minute bike ride), you’ll be surprised by how easy it is to get out of the car and onto two wheels, having fun and saving the planet along the way.
