Architects of the Podium: How Nine Coaches Built Olympic Champions

Every coach on a pool deck is asked the same question sooner or later: how much is enough? The coaches in this article answered it in very different ways. Some asked their swimmers to cover distances that still sound unreasonable today; others counted heartbeats, filmed strokes underwater or protected rest as carefully as work. Looking at them side by side is less about choosing a winner than about understanding what each approach is really trying to build, and why it worked for the athletes who trusted it.

Volume and the will to endure

Philippe Lucas

Philippe Lucas is best known in France as the coach of Laure Manaudou, and later of the open water champions Aurélie Muller and Sharon van Rouwendaal, who won the 10 km at the 2016 Rio Olympics. More recently he guided Anastasiia Kirpichnikova to silver in the 1500 m freestyle at the Paris 2024 Games. His reputation is built on hard, long training, and he wrote about his career and methods in Entraîneur (Lucas, 2008).

What is interesting is that Lucas himself pushes back against the idea that he simply piles on kilometres. In a long interview in 2025, he argued that distance swimmers need endurance but that speed and explosiveness still matter, even over 1500 m. He also described individual programmes for swimmers in the same event, varied training, and the need for the coach to change before the swimmer does (Bidault, 2025). The volume is real, but it is a means, not the method.

Volume: very high. In 2007, Europe 1 reported that Manaudou swam between 15 and 17 km a day under Lucas (Europe 1, 2007).

Dick Shoulberg

Dick Shoulberg coached at Germantown Academy in Pennsylvania for 44 years, from 1969. His swimmers trained seven days a week, and he believed the 400 m individual medley taught every stroke and every quality a swimmer needs. Between 1980 and 2000, he had a swimmer on every US Olympic 400 IM team but one (Swimming World, n.d.-b).

His best-documented session shows how far he was willing to go. To prepare David Wharton for the 1986 World Championships, Shoulberg had him swim a continuous 16,000 m long course IM on Columbus Day 1985, in 250 m blocks of butterfly, backstroke, breaststroke and freestyle. The set was repeated every 28 days, each time 3,000 m shorter, down to 1,000 m two and a half weeks before the trials (Stott, 2020). Wharton went on to set world records in both IM events and won Olympic silver in the 400 IM in Seoul in 1988.

Approach: very high aerobic volume, built around the individual medley.

Gregg Troy

Gregg Troy coached the University of Florida for twenty years, from 1998 to 2018, after two decades at the Bolles School. He was head coach of the US men’s Olympic team in 2012, and more than 80 Olympians from 23 countries passed through his programmes, among them Ryan Lochte, Caeleb Dressel, Elizabeth Beisel and Anthony Nesty (ISHOF, n.d.-b). Dressel went on to win nine Olympic gold medals.

Troy is remembered less for a single signature set than for a culture of relentless work, discipline and belief. His athletes were expected to own their training and to bring the same standard to every repetition, whether anyone was watching or not.

Documented sets: in a December 2005 morning session for Ryan Lochte, the main work included 4 x 400 IM on 5:00 to 5:15 and 16 x 50 butterfly, within a 9,200-yard practice (Swimming World, n.d.-d). One of Troy’s favourite distance sets descends through a 500, 400, 300 and 200, each swim faster than the matching split of the one before, repeated three to five times and finished with fast 100s (Poirier-Leroy, 2016a).

Approach: a large aerobic base first. His plan for the 2017 summer season opened with 50,000 to 60,000 m a week of aerobic work, then reduced volume by 10 to 20% a week as the focus moved to racing (Stott, 2019).

What these coaches share is less a method than a conviction, applied every day, and an athlete who believes in it.

Science and measurement

James “Doc” Counsilman

Doc Counsilman is the starting point for much of modern swimming science. At Indiana University, where he coached from 1957 until 1990, his teams won six consecutive NCAA titles from 1968. He used underwater photography for stroke analysis as early as 1948, designed a pace clock for interval training, researched the role of lift in propulsion and studied hypoxic and altitude training. Mark Spitz, who won seven gold medals at the 1972 Munich Olympics, swam for him (ISHOF, n.d.-a).

His book The Science of Swimming (Counsilman, 1968) was reprinted many times and shaped coaching education around the world. He also practised what he preached: in 1979, at 58, he became the oldest man to swim the English Channel.

Jon Urbanchek

Jon Urbanchek coached the University of Michigan from 1982 to 2004 and worked with 34 Olympians, including the double Olympic 400 IM champion Tom Dolan. His lasting contribution is the colour-coded training system, which sorts training intensities into zones linked to heart rate and perceived effort, so that every set has a clear physiological purpose (Swimming World, n.d.-c). Coaches still use versions of it today.

The zones: White and Pink for aerobic work, Red for threshold, Blue just above threshold, Purple for race pace and Green for lactate work, each tied to a heart-rate range and a rest interval (Fish, 2022). Aerobic and threshold colours dominate early in the season, with Purple and Green added as the taper approaches.

Approach: high volume organised around threshold.

Michigan was also home to Mike Barrowman, the 1992 Olympic 200 m breaststroke champion and world record holder, although his personal coach was the Hungarian Jozsef Nagy, who developed his wave-style breaststroke (Swimming World, n.d.-e). The two stories together show how a science-based team environment could host very different technical ideas.

Bob Bowman

Bob Bowman coached Michael Phelps throughout a career that produced 28 Olympic medals, 23 of them gold, and later guided Léon Marchand to four individual gold medals at the Paris 2024 Olympics. He set out his principles for a general audience in The Golden Rules (Bowman, 2016).

One of his best-known ideas is that adversity should be trained, not avoided. Bowman explained that he looked for ways to give Phelps adversity in practice and at meets. When a young Phelps forgot his goggles before a junior race, Bowman kept them back to see what he could do; Phelps won. Years later, in the 200 m butterfly final in Beijing in 2008, his goggles filled with water and he won in a world record time (Quartz, 2012). Preparation, in this sense, includes preparing for things to go wrong.

Documented set: on 19 October 2000, a 15-year-old Phelps swam 10 x 400 freestyle, starting on 4:45 and dropping the interval by five seconds on each swim. His times came down to 3:40 on the last one, in a practice of about 9,500 yards (USA Swimming, 2004).

Volume: high. Phelps averaged around 80,000 yards a week while training at Michigan from 2004 to 2008, and roughly a quarter of a workout was often kicking, done at full intensity (SwimSwam, n.d.).

Speed, rhythm and pace

Dean Boxall

Dean Boxall coaches at St Peters Western in Brisbane and is known worldwide for his emotional celebration of Ariarne Titmus’s win at the Tokyo Olympics. Titmus won four Olympic gold medals in total, the 200 m and 400 m freestyle in Tokyo, then the 400 m freestyle and the 4 x 200 m freestyle relay in Paris, before retiring in 2025. At the Paris Games, Boxall’s swimmers won 18 medals between them, and Mollie O’Callaghan and Titmus finished first and second in the 200 m freestyle (SwimSwam, 2024).

His squad shows how much world-class training partners can lift each other. In the same group, Titmus and O’Callaghan pushed each other to become the two fastest women in history over 200 m freestyle, and the coach’s energy on deck is part of the training environment.

David Marsh

David Marsh led Auburn University from 1990 to 2007, winning seven NCAA men’s and five NCAA women’s titles. He then built SwimMAC Carolina’s Team Elite, a professional group for post-graduate swimmers, and was head coach of the US women’s team at the 2016 Rio Olympics (Swimming World, 2015). At those Games, his Team Elite athletes included Anthony Ervin, who won two gold medals, including the 50 m freestyle, and Ryan Lochte.

Marsh’s contribution is partly structural: he showed that sprinters and experienced athletes could keep improving well beyond university in a dedicated, professional training group.

Documented set: in The Swim Coaching Bible, Volume 2, Marsh describes a high-intensity set in which swimmers start at top speed and try to hold it as long as possible, with short active recoveries to keep lactate under control and a modest total distance (Poirier-Leroy, 2019).

Approach: speed and lactate tolerance rather than volume.

Alberto Castagnetti

Alberto Castagnetti, an Olympic swimmer himself in 1972, coached the Italian national team from 1987 until his death in 2009. He worked with Giorgio Lamberti, Domenico Fioravanti and Federica Pellegrini, who set nine world records in the 200 m and 400 m freestyle under his guidance and won the Olympic 200 m freestyle in Beijing in 2008. He kept learning throughout his career, attending American Swimming Coaches Association clinics and studying Counsilman’s Science of Swimming (Swimming World, n.d.-a). The link between the two men is a reminder that coaching knowledge travels.

Yardage, threshold or race pace?

The table compares the training approach of these coaches, based on the sources cited in this article.

Coach	Volume	Main intensity focus
Philippe Lucas	Very high (15–17 km a day for Manaudou)	Aerobic endurance, with speed work
Dick Shoulberg	Very high	Aerobic, individual medley endurance
Gregg Troy	High (50–60 km a week in the base phase)	Aerobic base, then race-specific work
Jon Urbanchek	High	Threshold, through the colour zones
Bob Bowman	High (about 80,000 yards a week, 2004–08)	Aerobic and threshold, with intense kicking
Doc Counsilman	–	Interval training, hypoxic work
David Marsh	Moderate	Speed and lactate tolerance

None of these nine coaches is a race-pace purist. Even Marsh, with his speed-endurance sets, and Troy, in the race-focused end of his season, build on a large aerobic base.

The other end of the spectrum: USRPT

Ultra-short race pace training (USRPT) was developed by Brent Rushall. Every repeat is swum at or faster than race pace, with short fixed rest of around 15 to 20 seconds, a total of about five to six times the race distance, and the swimmer stops at the first failure to hold pace (Rushall, 2016). Its best-known elite advocate is Michael Andrew, coached by his father Peter Andrew. Andrew won the 100 m breaststroke at the 2021 US Olympic Trials and an Olympic gold medal in the 4 x 100 m medley relay in Tokyo. His father explained the choice simply: it is about specificity (VanDriessche, 2022).

The scientific evidence is still thin. A systematic review by Irish researchers at the University of Limerick found no peer-reviewed intervention studies of USRPT in competitive swimmers. They concluded that it appears to be a form of high-intensity training, and that it is best used with caution, as one method within a varied, periodised programme (Nugent et al., 2019).

Cameron McEvoy: less swimming, more speed

Cameron McEvoy is not a USRPT swimmer, but few elite swimmers have gone as far in cutting pool volume. As a 13-year-old he was swimming around 70 km a week, and for much of his senior career around 30 km a week. After the Tokyo Olympics he rebuilt his training around the 50 m freestyle, borrowing ideas from sprinters in athletics and track cycling: train less, train at very high intensity, hold that quality, then build again (AAP, 2024). He now works with coach Tim Lane, whose view of the job is simple: the athlete’s goals define it (SwimSpam, 2024).

The programme itself is striking. By his own account he swims probably no more than 2 km a week, and during one four-month block in 2024 he was in the pool only twice a week. Most of the work happens in the gym: heavy strength and power sessions in the morning, built around lifts such as deadlifts, pull-ups and bench pulls, with core work, then mobility and recovery in the evening and a full rest day every third day. In the water, the efforts are very short and very fast: 10 m bursts with fins against resistance, 15 m sprints, and a warm-up of five or six 15 to 20 m efforts building from about 70% to maximum (Poirier-Leroy, 2025).

The results speak for themselves. McEvoy became world champion in the 50 m freestyle in 2023, Olympic champion in Paris in 2024, and in 2026 set a new world record in the event (Forde, 2026). His approach remains the exception rather than the rule: published data suggest that elite swimmers still do around 86 to 90% of their training at low and moderate intensity (Nugent et al., 2019).

Is McEvoy alone?

Not entirely. In the United States, Van Mathias, who holds the American records in the 50 m and 100 m breaststroke, follows what Sports Illustrated calls the “McEvoy Method”: shorter, faster training, with sessions written by Indiana University sprint coach John Long Jr. (Forde, 2026). It is a fitting twist that this experiment is taking place at Counsilman’s old university.

Florent Manaudou, Olympic 50 m freestyle champion in London in 2012, shows a middle way. Under Romain Barnier in Marseille, whose influences include David Marsh and David Durden from Auburn, the principle was to train to race: pool work was either very easy or very fast, speed was addressed in every session, and dryland included three weight sessions a week and 50 to 100 km of cycling. His pool volume, around 30 to 45 km a week in the 2011–12 season, was far below the distance swimmers in this article but far above McEvoy’s (Poirier-Leroy, 2016b).

Money in the bank?

As a coach, I would add one important point. McEvoy did not arrive at 2 km a week as a beginner. He spent the best part of fifteen years doing high-volume training, from 70 km weeks as a teenager to 30 km weeks as an Olympian, and those years are money in the bank. A young swimmer copying his week without that history would be copying the end of the story, not the method.

The science gives a more nuanced picture of what stays in the bank. Aerobic fitness is not stored for long. In highly trained athletes, maximal oxygen uptake can fall by 4 to 14% within four weeks of stopping training, and in swimmers the oxidative capacity of the muscle has been reported to fall sharply within a single week (Mujika & Padilla, 2000). Issurin (2010) estimates the residual effect of aerobic endurance training at about 30 days, and that of maximal speed at only around five days, which may be one reason McEvoy trains speed so frequently.

What years of volume seem to leave behind is something different: highly refined technique and feel for the water, a body that tolerates heavy loading, and possibly a structural “muscle memory”. In studies on rodents, the extra nuclei that muscle fibres gain through training were retained after detraining, which may make it easier to rebuild muscle later (Bruusgaard et al., 2010), although how far this applies in humans is still debated. The bank, in other words, is less about aerobic fitness than about skill and robustness, and McEvoy is spending it wisely.

What the comparison teaches

As a coach, I find the differences between these nine coaches less important than what they share. Each held a clear conviction about what produces performance, whether volume, measurement or speed, and applied it with complete consistency over many years. Each also adapted it to the athlete in front of them: Lucas with individual programmes, Shoulberg through daily conversation with every swimmer, Bowman by building adversity around one exceptional talent.

A word to young swimmers

One warning matters more than any set in this article. McEvoy’s story is easy to misread as proof that less training is the key. For a young swimmer who has not yet built years of aerobic work, technique and robustness, it is not. Very high-intensity work is also demanding on a body that is still growing: the Limerick review describes USRPT-style sessions as highly stressful and cautions against high volumes of them for young swimmers (Nugent et al., 2019). In my experience as a coach, high-intensity training without a qualified coach watching technique, load and recovery is one of the fastest routes to injury and burnout.

Young athletes should also be careful not to idolise one champion. Every athlete in this article had a different body, a different coach, a different training group and a different life outside the pool. What worked for McEvoy’s morphology and history, or for Phelps’s, will not transfer directly to a teenager in a club programme. The best thing a young swimmer can copy from these champions is not their training week, but their consistency, their trust in a coach and their patience.

The lesson for coaches, and for leaders outside sport, is that there is no single correct system. What matters is a method you can explain, measure and believe in, an athlete who trusts it, and the patience to apply it every day. The sets change. The conviction does not.
