Refers to a process by which the body produces energy for movement by breaking down carbohydrates without oxygen. You will find yourself out of breath and gasping for air. You will not be able to sustain exercise in an anaerobic state for very long.
A level of exercise intensity beyond which the body cannot consume oxygen fast enough to support the energy demand. As a result, lactic acid begins to rapidly accumulate in the blood, hastening exhaustion. Also known as lactate threshold.
Nutrients that attach themselves to free radical molecules, thereby neutralizing them and preventing them from damaging tissues.
To suddenly increase riding intensity on the bike in order to escape competitors, meet the challenge of a hill, or for other similar reasons.

An acronym used in race results; it stands for “did not finish.”
A technique whereby a triathlete runs from the beach into the surf and dives forward, then stands, runs, and dives again, and so on, until he or she is out far enough to keep swimming.
Gaining an energy advantage by following in the slipstream of another cyclist or swimmer. Bicycle drafting is illegal in most triathlons.
A short-duration exercise involving a modified version of swimming, cycling, or running that is practiced for the sake of technique or power enhancement.
To suddenly leave behind another cyclist on a training ride or in a race.
The amount of time that an individual workout lasts.

Another word for economy.
Mineral nutrients (sodium, chloride, magnesium, and potassium) that aid muscle contraction and nerve impulse transmission by conducting bioelectrical signals.
The ability to work at a relatively high intensity level for a long period of time.
A type of running workout in which an athlete plays with his or her pace by whim.
The total or average number of workouts a triathlete performs in a specified amount of time.
A state of feeling relatively nonfatigued.
A form of strength training that simulates components of athletic movement patterns against resistance in order to increase the power with which an athlete is subsequently able to perform these movement patterns.
A sugar derived from dietary carbohydrate that serves as a primary muscle energy fuel during exercise.
A long chain of glucose molecules that is stored in skeletal muscle and liver and serves as a primary muscle fuel source during exercise.
To ride one’s bike very fast.
To reach a state of total exhaustion and sharply reduced ability to perform.
A dangerously low concentration of sodium in the blood that can result from the combination of heavy perspiration and failure to ingest sodium during prolonged exercise.
The rate at which an athlete burns energy for movement relative to his or her maximum capacity to burn energy for movement in a given mode of exercise.
A segment within a type of workout in which high-intensity efforts of a given distance or duration are separated by recovery periods of a specified duration. In cycling and running, it is usually the high-intensity segments that are called intervals, whereas in swimming, it is usually the combination of a single high-intensity swim effort and the subsequent rest period that is called an interval.
A type of swim shorts for men that fits tightly and covers the legs down to the kneecaps.
Awareness of the sensation of the body’s position and movement in space
An intensity level of exercise above which the metabolic waste product lactic acid accumulates in the blood faster than the circulatory system can remove it. Also known as the anaerobic threshold.
A compound that is produced in the body primarily as a byproduct of anaerobic metabolism.
The longest (or only) interval set in a swim, bike or run workout.
To struggle with too high a gear selection.
Short for maximum heart rate – that is, the highest heart rate one can achieve in swimming, cycling, or running. Usually one will have a different max HR or each discipline.
A state of being ahead of the main cycling pack, on a training ride or a race.
Excessive medial rotation of the foot during the foot-strike portion of the running stride.
A ratio of training to rest that is insufficient to allow complete recovery from and adaptation to training stimuli.
Dysfunction in a bone, muscle, or other soft tissue generally resulting from heavy repetition of flawed movement patterns.
One’s rate of swimming, cycling, or running
A single-file line of cyclist in training.
Recovery in the form of inactivity.
A brief window of maximum athletic performance potential that occurs at the end of a complete training cycle and taper.
The last of three main phases in the triathlon training cycle, during which a triathlete focuses on performing highly race-specific workouts and getting adequate rest.
A training method that involves arranging various types of training in a sequence that will produce the highest possible level of fitness by the end of the cycle.
A period of training that is characterized by a focus on a certain specific types of training. There are three basic phases in triathlon training: base, build, and peak.
A combination of speed and strength.
Short for “personal record” – one’s personal best time for a standard swimming, cycling, running or triathlon race distance.
Refers to a type of workout that emphasizes working at or above the anaerobic threshold.

A hard-effort segment within an interval or strength workout.
A period of inactivity between segments of a workout or between workouts.

Sores on the groin or buttocks that are generally caused by pressure and friction during cycling and sometimes subsequent infection.
The ability to swim, cycle or run quickly. Also, an intensity level of swimming, cycling, and running that is predominantly anaerobic and serves to improve economy, anaerobic metabolism, and lactic acid tolerance.
An interval-type running workout that emphasizes speed intensity and which usually takes place on a running track.
