Every session is a structured workout, so it pushes straight to your Garmin, Wahoo, Polar or Coros watch with the intervals and targets already built in.

New to the Olympic distance, or stepping up from a sprint? This is a 16-week build across swim, bike and run that brings you to the start line genuinely ready for the longer day: fit, durable and confident. The Olympic distance rewards patient aerobic endurance, not cramming.
WHAT'S IN EVERY SUMMIT PLAN
Coaching built in, not just a list of workouts.
✓HR-anchored to your own threshold
Targets are set from your own heart rate, so they scale to you, not a generic chart.
✓About 80 percent easy
Most of your running kept genuinely easy, with a smaller, sharper share of hard work. Endurance research links the fastest marathon and half-marathon times to more easy running, not more hard.
✓Structured to your watch
Every interval downloads to your device and guides you in real time.
✓A weekly coaching note
Plain English, every Monday: what matters most and what to drop when life is loud.
✓Three doses every week
Full, reduced and minimum, so a hard work or family week never derails the plan.
✓A day-one guide and workbook
The reasoning behind every session, with every term defined in full.
THE INTENSITY THAT GETS YOU THERE
Most of your training, easy.
A big aerobic base across swim, bike and run, with a smaller, sharper dose of hard work. The distribution behind durable endurance.
Easy ~80%Hard
Polarised training has the strongest evidence, so these plans are built that way. Pyramidal training is also effective, so in one-to-one coaching the balance is tailored to your stage of training and your life load.
Want to know where your training load sits in the typical age-group triathlon population? It is the focus of my PhD research (the TrainingPeaks Coach Blog I wrote →).

HOW IT IS BUILT
What it is built on
Built the way the Olympic distance should be: a patient, mostly-easy aerobic base across the three sports, the bike carrying the load and the run built protectively, with strength to keep you healthy.
Brick runs off the bike teach your race legs, and a measured dose of race-pace work late in the build rehearses race effort without overreaching.
It opens with an orientation week and a benchmark week (swim, bike and run tests), builds with deloads so the load becomes fitness, peaks about two weeks out and tapers in fresh. It is built to the same standards behind every Summit plan.
THE SUMMIT COACHING CYCLE
Coach yourself the way we would.
This is the rhythm we run in one-to-one coaching, and we encourage you to run it yourself when self-coaching. The plan prescribes the training; you measure, monitor and manage, week to week, and each step feeds the next.
PPrescribe
The plan designs each week with intent, built on the method above.
MeMeasure
Capture every session, and just as important, how it actually felt.
MoMonitor
Watch the trends, your fatigue and your life load, not just one session.
MaManage
Adjust, progress or back off, then it feeds into the next week.

ENDURANCE RESULTS FROM SUMMIT ATHLETES
Real results, from real endurance athletes.
50-min 70.3 PB, and a first Ironman finish“I reduced my Ironman 70.3 PB by 50 minutes in less than 12 months with Leighton, and he coached me to my first Ironman finish.”
Andrew Hyde · First Ironman finish 40 minutes off a 70.3“Exceptional, personalised service. Leighton provides great insights and really knows what endurance training is all about. I reduced my Ironman 70.3 time by 40 minutes.”
Scott Hunter · Ironman 70.3 athlete Before you start
You should be able to swim, bike and run a few times a week and be comfortable swimming continuously. The plan opens with an orientation week and a benchmark week that set your zones. Going long after this? The 70.3 Foundation plan is the next step. Swims are written for the pool; treat any open-water session as an optional extra and never swim alone.
FROM PLAN TO COACHING
A plan gives you the structure. Coaching adds the person reading the data.
Buy this plan, and if you later move to one-to-one coaching with Dr Leighton Wells, PhD (Sport Science), MAppSpSci, your first month is free. We pick up from where the plan has taken you, with your training built and adjusted around you, week to week.
Delivered through TrainingPeaks and loads into your calendar from your chosen start date. Train to your own limits and seek medical advice before starting a new program.
I coach triathletes, runners and IRONMAN athletes who want training that fits real life, not just a race calendar. I’m a sport scientist with a PhD in Sport Science, a Master of Applied Sport Science and a seven-time IRONMAN finisher, so it’s evidence-based but lived-in. We read your data and how training is actually landing, keep most of it genuinely easy, and progress in steps you can absorb. If you want a coach who listens, adapts and explains the why, I’d love to work with you.
