This Sunday, Minneapolis (home to Utne Reader HQ) will play host to the traveling circus that is the Urban Assault Ride, an event that annually graces 13 cities across the country by pitting pairs of cyclists against bizarre obstacles in a manner reminiscent of a scavenger hunt.
It's an event with an eye towards environmental responsibility. All sponsors organize their businesses around sustainable practices, they compost or recycle 95% of the junk left over after the race, and as much as possible they use biodeisel fuel to power the vehicles that take their gear from city to city. Have a look:
