I like this ad. Stress, regret, sadness literally falling away while you run. Turns out the model in this ad, Danielle Jayne, has been on the cover of Runners World a couple of times. At 6'3" tall and 158lbs* she qualifies as a giant runner.
*OK, I have no real idea how tall she is or how much she weights. Fortunately the fact that running can make you feel better isn't size dependent.
