TRES HERMESSpice up your morning five-miler with 125 of your favorite songs. With its pack-of-gum-size wireless sensor clipped to your laces, the MP3 Run tracks your speed, distance, and pace. Hit a button and the unit will cut into “Eye of the Tiger” with a progress report (“Time, three minutes; pace, eight minutes per mile; distance, 0.5 miles”).
Bonus: A sweet ergo arm strap and rubber case.
Bummer: Distance and pace features don’t work on bikes.
