Plan Description
Go to sample weeks and training-load structure ↓
You already run consistently, and you want more than to just finish. This is a focused 14-week build toward a strong, even half-marathon: a race you control, rather than survive. A strong half is race-specific endurance and a controlled race pace, not piling on junk miles. New to racing the distance? Build a base with the 10K plan first.
WHAT'S IN EVERY SUMMIT PLAN
Coaching built in, not just a list of workouts.
Targets are set from your own heart rate, so they scale to you, not a generic chart.
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.
Every interval downloads to your device and guides you in real time.
Plain English, every Monday: what matters most and what to drop when life is loud.
Full, reduced and minimum, so a hard work or family week never derails the plan.
The reasoning behind every session, with every term defined in full.
THE INTENSITY THAT GETS YOU THERE
Most of your running, easy.
A big aerobic base with a smaller, sharper dose of hard work. The distribution the research ties to the strongest endurance results.
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.
Endurance research links the fastest marathon and half-marathon times to more easy running, not more hard (Muniz et al., 2024, Sports Medicine →).

HOW IT IS BUILT
What it is built on
Built the way the evidence says a half-marathon is built: a mostly-easy aerobic base, a carefully limited dose of harder work, and long runs progressed by time rather than ego.
In the second half of the plan you rehearse half-marathon pace, so race day feels familiar, not improvised. Threshold work lifts your red-line, the fastest pace you can hold before it tips over.
The plan peaks about three weeks out, then tapers cleanly. Strength is built in twice a week for durability and economy, and every run is anchored to your own threshold, your LTHR (Lactate Threshold Heart Rate), set from a 5 km field test. It is built to the same standards behind every Summit run 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.
The plan designs each week with intent, built on the method above.
Capture every session, and just as important, how it actually felt.
Watch the trends, your fatigue and your life load, not just one session.
Adjust, progress or back off, then it feeds into the next week.

ENDURANCE RESULTS FROM SUMMIT ATHLETES
Real results, from real endurance athletes.
“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“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 athleteBefore you start
You should be running comfortably three to four times a week, and able to run for about 45 minutes without stopping. Newer than that? Start with the 10K plan and step up when you are ready. The plan opens with an orientation week to settle in and set up your watch, then a benchmark week that sets your zones from a 5 km field test, so nothing in the build is guesswork.
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, 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.
