Rachael took 22 minutes off her 70.3 time in just 6 months, highlighted by a 15-minute run improvement and nearly 3 minutes saved in transitions. She rose from 14th to 3rd in her age group and qualified for the IRONMAN 70.3 World Championships, a huge milestone that reflects her rapid rise through the field.
Lachlan delivered an exceptional breakthrough, securing a podium finish in his first-ever Ironman through mature pacing, strong bike execution, and a brilliantly controlled marathon. He also qualified for the Ironman World Championships on debut, something extremely rare at any level. On top of that, he improved his standalone marathon by nearly 5 minutes this year while averaging only 50 km per week, far below the 100+ km he once ran as a pure runner. His development in durability and efficiency has been enormous.
Rodney improved his 70.3 finish time by 12 minutes year-on-year, moving from 6:02 to 5:50. His run split alone improved by almost 20 minutes, dropping from 2:41 to 2:22, showing a huge leap in pacing and durability. He had completely stopped training after his previous Melbourne 70.3 and only restarted structured work 12 weeks before the 2024 race. And with his 2023 swim being significantly shortened, his true full-course improvement is even greater than the headline suggests.
Riley took 24 minutes off his half-iron time at West Sydney 70.3, posting 4:11:08 with a 27:08 swim (1:26/100m), 2:15:35 bike (39.8 km/hr), and a 1:25:12 run (4:02/km). His bike split improved by 6 minutes and his run by a huge 16 minutes, putting him 9th in the M18-24 age group. A clear step up from his Husky breakthrough, and a sign there is still plenty of runway ahead.
After just 12 weeks of structured training, Riley won his M15-19 age group at Husky and finished 13th overall with a 2:14:22 Standard Distance performance. A massive early breakthrough and a sign of genuine long-term potential.
Before coaching, Jeremy was performing well at the club level, winning the B-Division Single Scull at Footscray Regatta and earning Male Champion at Footscray City Rowing Club. After beginning structured training, he stepped decisively into higher-level racing, qualifying for the Victorian State Championship Final in the Lightweight Men's Single, finishing 5th in the state with a 2k time of 7:47.98, and racing the A-Grade Single among some of Victoria's strongest scullers. A clear progression: B-division winner to club champion to state-level athlete to top-5 in Victoria.
Dylan delivered a major step forward at Melbourne 70.3, taking around 30 minutes off his bike split and about 9 minutes off his run compared to his previous 70.3 performance. The swim can't be compared due to the swim cancellation, but the bike and run gains alone resulted in a standout 4:10 finish, marking a huge lift in speed, strength, and competitiveness.
Zac produced a massive breakthrough over the marathon distance, running 4:11 and taking 27 minutes off his previous best in just 6 months. A clear sign of rapid improvements in aerobic capacity, pacing, and overall durability, with plenty more upside still to come.
Zack dropped an 11-minute personal best in a sprint-distance triathlon after just three months of structured training, achieved without a taper and straight out of a normal training week. Zack is one of the most consistent athletes on the roster and is a great example of what can be achieved.
Craig came in from pre-written programs, unsure about the value of 1:1 coaching. After just 10 weeks of structured training, he took 25 minutes off his 70.3 time at Geelong, going from 5:12 to 4:47. His bike split dropped from 2:35 to 2:23, nearly 12 minutes faster. His run went from 1:57 to 1:44, nearly 13 minutes faster. He finished 22nd in his age group after placing 75th the year before. One of the most consistent athletes on the roster and a clear example of what focused, individualised coaching can produce in a short timeframe.
Across a single race season, Kyle cut 15 minutes and 22 seconds from his 70.3 time, including a 7-minute faster bike and 4-minute faster run. He achieved this while self-coaching using the Tremayne Performance Method, earning his professional licence just 10 months after his first race, and after only 2 years of total training. A rapid rise built on discipline, structure, and the same methodology now used across the Tremayne Performance athlete roster.
The Problem
You have had the generic plan that ignores your schedule. The coach who never looks at your data. The training week copied from a spreadsheet. You have done the work and watched your race results stay the same. The issue was never your ability. Your program was never built around you.
Every athlete here gets a periodised program built from their own performance curve, direct coach access, and a plan that adapts when work, family, or body needs it to. Training fits your life, not the other way around. Personalised triathlon coaching built on your physiology, not a template.
The Process
A systematic 6-phase approach that takes you from where you are to where you want to be, with precision at every step.
Build volume safely, prevent injury, and establish schedule consistency that fits your life.
Establish your individual heart rate values to personalise every single workout from day one.
Develop foundational endurance across swim, bike, and run with structured progression.
Heart rate normalised power and pace curves built from every session you complete. The whole shape of your engine, not a single number.
Fully individualised training with 6–8 week testing blocks to track progress and adapt.
Targeted programming optimised for your key events. Arrive at the start line ready to execute.
The Edge
The full shape of your fitness, built from the work you are already doing.
A single number cannot describe an athlete. An FTP test gives you one wattage. A 5K time trial gives you one pace. Neither tells you how your fitness is shaped or how it holds up under fatigue.
Most programs you have ever followed were not built for you. They were built for someone else in another era, printed in a training book, and applied to anyone who picked it up. Every layer carries error. Zones from a population average. Thresholds from a single test. Distributions from elite-volume athletes applied to working professionals. The assumptions stack until what reaches the athlete bears almost no relationship to their actual physiology.
The performance curve works differently. It starts from the rawest data we have: the actual power you produced, the actual pace you ran, the actual heart rate cost of producing it. Every point on the curve is a real number from a real session. The athlete is the input. The data is the analysis. The program is what falls out the other side.
Thirty seconds out to several hours. A short surge matters to an Olympic-distance athlete. A three-hour sustainable output matters to an Ironman. One number cannot describe both. The curve does.
The information lives in the shape, not in any single point. Whether your 15-minute power sits at 90 percent of your 5-minute power or 70 percent tells us which race you are built for, and exactly what the next block of work needs to develop.
Every ride and every run updates the curve. Heart rate normalisation strips out the daily noise of heat, fatigue, sleep, and hydration so real physiological change shows up in the numbers instead of being buried by them.
That is what first principles actually look like.
Same 20-minute power. Same 60-minute power. A single-number test would prescribe identical training for both. The curve tells you they need completely different programs.
Flat curve. Holds nearly 80 percent of FTP at three hours. A long-course engine. Programming here is about growing the whole curve, especially at the durations that actually decide the race.
Steep curve. 3.5x FTP at thirty seconds, but only 60 percent of FTP at three hours. A short-course engine. Programming protects the top end while building sustainable aerobic output underneath it.
Any single-number test treats these two athletes as the same athlete. Every duration where the real coaching decisions get made is completely different. The curve is the only tool that sees it.
Real progress is not one number going up. It is the whole curve lifting, with the ratios between durations telling you the shape is right.
Twelve weeks of structured work. No lab. No maximal tests. No lactate meter. Heart rate and power only.
The whole curve lifts. Every duration climbs, and the shape flattens as sub-threshold output grows faster than peak output, because that is where the volume sat. For a long-course athlete this is exactly what a good block is supposed to deliver. Growing the whole curve, not trading one end for the other.
Trading ends of the curve is called pivoting. It is a deliberate late-stage choice during race preparation, not a sign of fitness improvement. Confusing the two is one of the most common self-coaching errors. The curve makes it impossible to mistake pivoting for progress.
Traditional tests give you one number from one day. The curve gives you every number from every day you train.
An FTP test answers one question. The curve answers every question that actually matters for building an individualised program.
Requires a power meter or smart trainer for cycling data and a GPS watch or foot pod for running data. Works with any Garmin, Wahoo, Polar, or Suunto device.
Your Coach
Head Coach, Tremayne Performance
I wasn't a gifted athlete. Growing up in Victoria, I chased team sports with nothing to show for it. Then in 2021 I found triathlon, and something clicked. I fell for the physiology, the structure, the idea that you could engineer performance through smarter training. By 2023 I had my professional license. Today I coach triathletes across Australia and the world.
For my first twelve months I trained using generic zones and cookie-cutter programs that weren't built for my physiology. I was doing the work but not getting the results. The moment I learned to individualise my program, to train based on my actual thresholds, everything changed. That principle is the foundation of every program I write. You get direct access to me. We talk, we review, we adjust. I care about the outcome.
