Triathlete running at dawn on a coastal road

Life-first performance. Ironman. Ultra. Built around your life.

Your life comes first.
Your training adapts to it.

Most training plans expect you to fit your life around them. This one flips that: connect Garmin or Strava, talk to your coach every day with a 30-second voice note, and get back world-class coaching — built by a British Triathlon Level 2 coach — that adapts around your work, your family, and your recovery. Not a generic plan. Your training, understood.

Real coaching experience. Your data. One conversation away — just talk, and your plan adapts.

The problem

Most training plans were written for people with nothing else going on.

They assume you can train twice a day. That your work is flexible. That your family understands. That you can nap after the long ride.

They're also full of junk. Sessions without purpose. Volume without progression. Effort without understanding. You grind, you get injured, you wonder if this was a stupid idea.

It wasn't a stupid idea. It was a bad plan.

The Endurance Lab runs on life-first performance: input your real commitments — work, family, sleep, recovery — first, and your training fills the gaps that actually exist. Not the other way around. The athlete who trains with purpose — who understands what every session is doing and why, and whose plan respects their actual life — outperforms the athlete who just logs more hours. Every time.

Open water. 5:30am. Nobody does this for fun. They do it because they know what it's for.
Why this is different

Your watch does the logging. You do the talking. The coach's brain does the rest.

Plenty of apps sync a Garmin or a Strava feed and call it "AI coaching." That's the easy part. The hard part — the part that actually changes your training — is judgement. That's what you're paying for here.

Connect your watch once

Garmin or Strava, linked in under a minute. Every run, ride, and swim flows straight into your athlete profile — pace, power, heart rate, elevation, the lot. No manual logging, ever.

Talk, don't type

After every session, send a 30-second voice note the way you'd message a mate: how it felt, what hurt, what's going on this week. No forms. No dropdown menus. Just speak, and it's logged.

A coach's brain reads it

Your data and your voice note are read together, against a real coaching methodology built by a British Triathlon Level 2 coach — archetypes, risk flags, phase logic. Not a generic pace-chasing algorithm.

Your plan adjusts, same day

Tired, injured, travelling, or flying? Your next session updates before you've finished your coffee. Not a static PDF from six weeks ago — a plan that's actually listening to you.

This is the sentence that matters: it isn't the wearable sync that makes this work — everyone has that now. It's what happens the moment after. That's the part we built.

Try it now — live

This isn't a mockup. Connect your Strava and talk to the coach right now.

Your Strava data

Link your Strava account to pull your last 10 activities straight into your athlete profile.

Talk to your coach

Type (or dictate with your keyboard's mic button) how a recent session felt. The AI coach reads it alongside your Strava data and replies like a real coach would.

How it works

A coaching system, not a fitness app.

Every session has a purpose. Every week builds on the last. Every plan is built around your life, your event, and your constraints — not a generic template.

You tell us everything.

Your event. Your timeline. Your available hours. Your equipment. Your strongest discipline and your worst one. Your injuries. Your travel schedule. Everything that matters goes in up front, so nothing gets assumed later.

We build your athlete profile.

From your inputs, the system produces a precise profile: your archetype, your constraints, your risk flags, and the plan type that fits your situation. You see it before your plan is built.

Your plan lands on Day 2.

A full structured training plan — swim, bike, run, strength — built around your available days and hours. Sessions delivered a week in advance. Every session has an aim, success criteria, coaching cues, and a link to what comes next.

You train. You talk. We respond.

Your watch data lands automatically. After each session, send a 30-second voice note on how it felt. The system responds with coaching logic: adaptation cues, reassurance, or a flag if something needs attention. No forms. Just talk.

You understand what you're doing.

One education piece per week, phase-matched to your training. Week 1 is Zone 2 — because that's what you're doing. Week 7 is threshold training — because that's what's coming. You don't just follow a plan. You understand why it works.

Life-first, always. Your plan adapts.

Business trip? Late nights? A kid off school? Enter your real commitments and the system builds training around the gaps that actually exist — it never assumes an empty calendar. Missed a session? It adjusts rather than expects you to make up the miles. Consistency across months beats perfection in any individual week.

See inside the coaching

The Foundations Course. Six weeks. Two paths.

Every athlete starts here — a 6-week accelerator that builds your baseline, your habits, and your confidence before the real training block begins. Choose the path that matches your goal.

Week 1

Foundations & Baseline

"Build from your life upward, not from the race backward."

Pace drop-off test, one long run at easy pace, one short run, one strength session. Baseline testing and your warm-up ritual, locked in.

Week 2

Accelerated Load & Time Efficiency

"Get more from less."

Strength-into-run simulation, long run with fuel practice, controlled speed intro. Early fuelling habits, formed under real fatigue.

Week 3

Confidence Week

"Control what you can — confidence beats comfort."

A full confidence simulation with race-day fuelling. The Reset Drill for handling "the wobble" mid-session.

Week 4

Durability & Pace Control

"Stronger for longer."

Progression runs, run-walk ratios for ultra distances, pacing strategy development, and fuel timing precision.

Week 5

Sharpening & Rhythm

"Find your race-day rhythm."

Back-to-back long runs, heat and night-running adaptation for longer ultras, and final nutrition fine-tuning.

Week 6

Consolidation & Handover

"Own the system — this becomes your method."

A final progress test, your personalised 8-week race-specific plan (50K to 100-mile), and your race-day routines, locked down.

What events do you coach for?

Primarily Ironman and 70.3 triathlons and ultra marathons (50K to 100K). If your goal is a long-course event that demands months of preparation, this is the right place.

I'm a beginner. Is this for me?

If you're new to structured training but not new to sport, yes. The system is built for people who are motivated and capable but have never had a proper coaching framework before. The education layer is specifically designed to fill that gap.

What if I can only train 6 hours a week?

The onboarding questionnaire captures your real availability — not an aspirational version of it. Plans are built around what you actually have, not what would be ideal. 6 hours, done purposefully, beats 12 hours done randomly.

Do I need a power meter and HR monitor?

No. Sessions are written in RPE (perceived effort) by default. If you have power or heart rate data, the system uses it. If you don't, you're not at a disadvantage — you just work with RPE zones, which are well-validated and used by elite coaches worldwide.

Who built this

I know what it actually costs to train for something hard.

British Triathlon Level 2 coach. First decade of my career coaching sport — primarily watersports. Competed in Ironman and a 100K ultra. CEO. Father of three daughters. Husband to a wife with her own demanding career.

I'm not writing plans for athletes who live in a training bubble. I'm writing plans for people who have to negotiate for every training hour and still have to justify it when the kitchen isn't clean and the school run ran late.

The Endurance Lab exists because I couldn't find a coaching product that took both parts of that problem seriously: the performance side and the real-life side. So I built one.

Everything in this system is built on British Triathlon coaching principles — sessions with clear aims, measurable outcomes, linked progression. Not because I'm interested in certification boxes. Because those principles produce athletes who improve consistently without breaking down.

Coaching as a primary career before moving into business — understanding of athlete development, not just fitness.

Competed at the distances he coaches

Ironman. 100K ultra. Off-road marathon. Short-course road racing. The plan comes from experience, not theory.

Running Endurance Lab as a side business

This is not his full-time job — which means it's built to work for people who can't treat training as their full-time job either.
