Okay I am sure you just snickered a bit, and truthfully we do to, but before you think this is all a word made up on the school grounds by some hyperactive kids, let me introduce you to what Fartlek actually means. From our friend at Runner’s World Magazine: Fartlek is Swedish for "speed play," and that is exactly what it’s all about. Unlike tempo and interval work, fartlek is unstructured and alternates moderate-to-hard efforts with easy throughout. After a warm up, you play with speed by running at faster efforts for short periods of time (to that tree, to the sign) followed by easy-effort running to recover. The Fartlek 5K brings the “play like” attributes of this long and well known running jargon/training term into a fun family oriented 5K. The event will feature a 5K Run/Walk and a Fartlek zone (where we will capture the fasted speed play participants) and a fun post-event expo.
