Reference excerpt

Joe Friel is an endurance sports coach, best known as an elite triathlon and cycling coach as well as an author. Friel holds a master's degree in exercise science and is a USA Triathlon and USA Cycling certified elite-level coach. He is a founder and past Chairman of the USA Triathlon National Coaching Commission. He has also been active in business as the founder of TrainingPeaks, a web-based software company, and TrainingBible Coaching. His views on matters related to training for endurance sports have been featured in such publications as VeloNews, Outside, Runner’s World, and The New York Times. Friel coached Ryan Bolton, an Olympic athlete and the winner of the 2002 Ironman Triathlon at Lake Placid. Friel uses the training philosophy of periodization developed by Tudor Bompa.

Worked examples

Example 1 — a first encounter with Joe Friel

Start with the simplest possible case. Write down what Joe Friel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Joe Friel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Joe Friel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Joe Friel

In research: Joe Friel appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Joe Friel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Joe Friel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, American triathlon biography stubs, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Joe Friel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
