This is Fartlek Day.

Gosta Holmer, an Olympian from Sweden who competed against Jim Thorpe, invented this interval program run on the trails and in parks.

Mr. Holmer developed it for the Swedish cross-country team in the 1930s, which did very poorly in European competitions, and Gosta wanted to motivate them.

He did!

This is your workout:

Warm up today,

60 minute fartlek,

six-time five minutes hard, five minutes easy

fifteen minutes of moderate to slow running after that.



get out of your wet clothes,



Larry’s Deep Thoughts: Fartlek is for the newbie runner and elite. It provides challenging work at whatever your level.
