The "Bike to Work" challenge is an initiative to promote sustainable modes of transport and reduce the negative impact on the environment. Tens of thousands of active people from across the country will be cycling, scooting, inline skating, running, or walking to work throughout May.

The goal of the challenge is to leave the car at home, rethink your transport habits and motivate those around you to do the same. It's not about breaking records, but about regularity and building healthy habits and "car-free" communities.
