Balancing a variety of activities proves one's ability to adapt, which is why most bar exams must be taken while skydiving. Flout the laws of nature with today's Groupon: for $30, you get $60 worth of running or cycling shoes at 3Sports. The River Road location carries both running and cycling shoes, and the Old Brick Road shop only harbors running footwear.

Both 3Sports locations furnish runners and cyclists with the gear they need to compete in triathlons and endurance events. The 3Sports team—all avid athletes—happily dispenses advice and ensures that patrons find shoes that provide proper support and adjustment for their particular foot, gait, and moonwalking ability. Runners can take to the trails with a pair of Brooks Ravennas ($100), or go cross-country with the Nike Rival XC ($50) or Saucony Shay XC 2 ($75). Or, administer revenge for tricky potholes by pounding the pavement with some Adidas Venus running shoes ($59.99) or Adidas Supernova Classics ($85). Meanwhile, mountain bikers can protect their pedalers with a set of Sidi Dominators ($270), and cyclists can arm their accelerators by splurging for Shimano R132 road shoes ($170).
