Improve your running experience and move on to Mr. McGwire's later works with today's Groupon: for $25, you get $50 toward running shoes and apparel at Downingtown Running Company.

Downingtown Running Company adorns sidewalk sprinters with all manner of athletic apparel, sporting more than 100 sundry kicks from such top shoesmiths as Asics, New Balance, and Saucony. Safeguard stompers from rough pavement and treadmills made of sandpaper with stylish foot-forts for men and women including Saucony’s Guide 4, Brooks' Adrenaline, and New Balance’s Minimus Trail or Rode ($100 each).
