TSICK (pronounced like the onomatopoeia word tsk) is defined as T for a Track workout, S for a Swim workout, and ICK is the feeling you get while working out on the track in sunny, 80 degrees, and 80 percent humidity.
The track workout began with a 2 mile warm up at a 7:40 per mile pace. The heart of the workout was a 3 x 1 mile repeat with only 1 minute rest between each mile. Each mile was run at a 5:40 per mile pace. The track workout concluded with an easy 1 mile cool down run to the pool for a 20 minute swim.
The "ick" feeling was during the run portion and the "ah" feeling was the relief enjoyed while in the pool.
