XC Terminology...saw this on a Colorado HS XC Website. 
Too good not to share...enjoy!  Coach Fillipow

Every sport has specialized terminology.
Cross country is no exception, except that cross country has less specialized terminology than most sports.

 Assistant Coach - a young, fast guy who can keep up with the kids the head coach can't keep up with any longer.

Carbo Loading – an excuse for the team to have a relatively inexpensive meal together. It’s highly doubtful that carbohydrate loading serves any useful purpose for a 5K race. In fact, it makes many people a little gaseous the following morning.

Chute – a place for runners to hurl while supported in the arms of an adult whose only sin was to volunteer to help out with the meet. It’s usually difficult to get help to volunteer for the chute more than once, especially more than once in the same season. For whatever reason(s), though, some volunteers forget this experience and can be duped into working the chute in subsequent years.

Core Strength – notoriously absent among individuals who have grown up consumed with eating, texting, and playing video games. The condition is addressed by doing a number of exercises that make athletes feel conspicuously self-conscious. “Okay, everybody, let’s get in the table position and do some fire hydrants!”

Course Map – a photocopied document typically in short supply at meets, worthy of a D+ in a third grade art class, and cleverly designed to confuse coaches and runners from visiting schools.

Cross Training – postponing the inevitable. Runners who are nursing an injury are often given some sort of non-impact aerobic workout to do for a day or two in hopes that stress reaction won’t turn into a stress fracture. Bicycling, elliptical, swimming, and water running are the workouts of choice. Most high schoolers are very poor water runners, all the more so when doing it without supervision. It takes some practice to do it even close to right. As an aside, never assign bicycling as a cross training workout for an athlete with patellar tendonitis.

Eligibility Check – a pointless exercise for nearly all cross country runners. Even having a team GPA of 4.0 is no guarantee that you’ll win the Academic Team Champions award for cross country. Contrast with ….

Games Committee – a group of coaches and school administrators with the unenviable task of arbitrating disputes arising out of meets. Much to the relief of all concerned, appeals are rarely filed or needed in cross country. Be suspicious, however, of anyone volunteering for a games committee assignment.

Hydrating – an activity crucial to a runner’s well-being, but dangerous to do during a school day where most teachers are reluctant to let students visit the restroom as a matter of routine. Life is cruel at times.

Intervals – a type of workout typically done at or near race pace. Athletes run a fixed time or distance (usually five minutes or less or one mile or less), recover for a fixed period of time (the “interval”), and repeat until the coach wearies of the process or the sun goes down.

IT Band – the name of choice for a future rock group made up of former distance runners who experience hip or knee pain while walking down stairs, doing squats, and a few such similar activities.

Fartlek – nothing resembling what it sounds like. Fartlek means “speed play” in some Scandinavian tongue. Or at least that’s what we’re told. Trouble is, everyone who’s told me that was either winking or had a nervous tic in their eyelid. The term refers to a run in which runners go faster, then slower, faster, then slower, and usually mostly slower by the end (unless they’re really fit).

Flats – lighter weight racing shoes, but distinguishable from spikes (see below).

Pack Time – the interval of time between a team’s first and last scoring runners. In some cases, minimizing this time becomes a team's strategy for a meet, a version of “No Child Left Behind” as applied to cross country. It’s fine to have a short pack time if your fifth runner can beat most teams' first runner. Of course, almost any strategy works well in that case. Opinion differs on whether a minimal pack time is good when your fifth runner isn’t that fast. The idea behind focusing on pack time is to “pull along” your last scoring runner. Sometimes it works and more frequently it doesn’t. Sixth and seventh runners are generally left to fend for themselves.

Recovery Day – a day where you get strength back for an upcoming harder workout. Typically, this means a 30 to 45 minute run. You should be impressed that people can do this much work and still call it “recovery.”

Rules Meeting – the annual convocation of coaches for the purpose of being informed about changes to rules that nobody knew were rules and arguing over interpretations of the uniform rule.

Spikes – lighter weight racing shoes with nasty metal protrusions on the bottom of the shoe. Spikes are rarely worn in Colorado as totally grass surfaces (where the nasty metal protrusions are actually useful for something besides shredding the lower leg of the runner in front of or behind you) are rare in our state. Spikes make an irritating “skritch, skritch, skritch…” sound when running over the hard surfaces that occur at some point on most Colorado cross country courses.

Stress Fracture – a season-ending injury and an excuse to purchase the fashion accessory of choice for distance runners—a black boot.

Tempo (or Threshold) Run – a run at a comfortably hard pace for a fixed duration of time, usually about 20 minutes. Most high school runners are perceptive enough to realize that “comfortably hard” is an oxymoron and therefore struggle with settling into the proper pace.

Trainer - meaning depends on context. Can refer either to the all-purpose running shoe that keeps entities like Nike, Adidas, Asics, etc. in the black or to the quasi-medical person seen by the person hoping for a waiver from the day’s workout.

Training Through – an all-purpose excuse for running poorly in a race, as in “I was just training through this race.” Sometimes, it is true, but the rationale is invoked more often than that.
