Plan Description
Go to sample weeks and training-load structure ↓
You already train consistently, four to five times a week, and you want a faster 5 km, not just another block of miles. You have the base. This is a focused 12-week build that works on your ceiling: your VO2max, your top sustainable speed, and how economically you hold it. A faster 5 km is won with sharp, race-specific work on a deep easy base, not by piling on volume. New to racing the distance? Start with the Beginner 5K plan and step up when you are ready.
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 deep easy aerobic base carries the engine, with a smaller, sharper dose of VO2 and threshold work where the 5 km is won.
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 fast 5 km is built: a deep, mostly-easy aerobic base, then a carefully dosed layer of sharp, race-specific work. Across the plan roughly four of every five kilometres stay genuinely easy.
The hard work is where short races are won. VO2 intervals at 5 km effort lift your aerobic ceiling, the engine behind your top sustainable speed, while threshold work raises your red-line, the fastest pace you can hold before it tips over. Strides keep your running economical and quick.
The plan opens with an orientation week and a parkrun or 5 km benchmark that sets your zones, progresses in absorbable steps with deload weeks, peaks near 53 km in its biggest week, then tapers cleanly so you arrive sharp. 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). 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 already be running comfortably four to five times a week. Newer than that, or new to racing the distance? Start with the Beginner 5K plan and step up when you are ready. Want to go further? The Advanced 5K plan carries more volume. 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 parkrun or 5 km time trial, 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.
