Practical biking is interrupted by goofy fun for this annual event. At the start of the race, two-person teams receive a list of checkpoints scattered throughout Minneapolis. They're charged with plotting a course to each via the city's bike trails. That's the practical part. It's once the cyclists reach the checkpoints that things get zany. At each stop, they must tackle an off-the-wall challenge that has included racing Big Wheel tricycles through a maze and doing belly flops on a giant Slip 'N Slide.
