Our mission

Empowering high performers for sustainable success through data-driven, human-first coaching.

What we do

Four pillars.
Run together.

Strength, body composition, endurance and health metrics, coached as one system rather than four separate problems. Move one at the expense of another and you lose both. Every plan is built around your real schedule, with direct access to your coach throughout.

01Strength

Held under aerobic load, not trained in isolation.

02Body composition

Leaner while training, never instead of training.

03Endurance

Faster at the same heart rate, from tested zones.

04Health markers

Sleep, HRV and bloods, read alongside the training.

Tom O’Cleary
Who runs this

From guesswork
to diagnostics.

I’m Tom O’Cleary. I spent years watching capable people train hard and get nowhere. Not because they lacked discipline, but because nobody had measured what was actually limiting them.

I did it to myself too. I ran a 3:17 marathon and assumed the answer was more volume. Testing showed my easy running had never been easy. 3:17 became 2:49, on less punishing training.

Who trains here

Calendars that
do not negotiate.

Founders, executives and endurance athletes, training around full lives rather than instead of them.

The Command Deck

Every decision,
backed by data.

Your numbers land in one place and I read them every week before anything in your plan changes. High performance is measured, not guessed.

Body compositionTracked as a trend, never a single reading
Our values

We do more than
run the numbers.

People are more than data points. That is why we take a whole human approach to wellbeing. From metrics to mood.

01

Partnership

We work hand in hand with you, adapting the plan precisely to your journey and your real life demands.

“I have a guide who believes in my potential and adapts to my needs.”
02

Commitment

A 365 approach, built to last. Continuous support that builds health and performance beyond short term gains.

“Long term growth is built on consistency, not quick fixes.”
03

Empowerment

We teach you our methods and give you the tools, so every decision becomes a deliberate step forward.

“I can see my transformation unfolding, so I believe in what I do.”
PEAKHUMAN™

Fifty-two weeks.
Gated by data.

Our flagship programme is a twelve month partnership, in five phases. You move on when the data says you are ready, because lasting change in endurance and body composition takes more than a twelve week block.

How to start

Three steps.
The first is one
message.

01

Book a consult

Message me on WhatsApp. It comes straight to me, not a form or a team.

02

The consult

We talk through your week, your goal and what has broken before. If it is not a fit, I will say so.

03

Your plan

Testing first, then a plan built around your real schedule. Nothing is written until the numbers are in.
