Athleticism is more than dodging projectiles, wrangling mascots, and dropkicking a computer after it beats you in chess. Outfit yourself for adventure with today's Groupon: for $20, you get $40 towards athletic apparel and shoes at Stride Ahead Sports in the Grant Park Shopping Centre.

At Stride Ahead, a staff of denizens dedicated to running shod the feet and sheath the musculatures of pavement pounders in high-quality, performance-supporting gear. Runners, skippers, and two-steppers can peruse a wide selection of breathable, durable apparel, such as the Asics Core pocketed shorts (34.95) and Sugoi Ready short-sleeve top ($39.95). Or, seek out time-reducing, distance-enhancing foot swaddlers, such as the Nike Air Pegasus ($119.95) and the New Balance MR759 ($134.95). The experienced staff helps each customer fulfill unique below-the-knee needs by discerning which shoes best enhance achievement, incite jealousy in earthworms, and prevent injuries.

Committed to fostering a love of foot flight, Stride Ahead promotes local amateur athletes and teams, and also gives athletes a chance to test-drive new threads every Saturday morning at 8:30 a.m., where the free running club departs from the store, reclaiming the streets and historically reenacting the world's most beloved stampedes.
