How RunZones works
From a folder of old runs to direction you can train on.
You already have years of data. RunZones turns it into a fitness profile, finds what worked before, and shows what needs to happen next.
Upload your history
Bring your past training, races and zones. Connect your watch so the system keeps learning.
Build your profile
Eight physiological systems, read honestly from your own data — strengths, gaps and readiness.
See the gap
What your best races were built on, compared with where you are now — the missing ingredient, named.
Train with direction
An adaptive plan and an execution guide for every session — the right zone, the right effort.
The difference
What makes RunZones different?
Not a generic dashboard. Not another AI wrapper. A performance system built on elite marathon experience, real physiology, and proper coaching logic.
Built from elite marathon experience
Shaped by Stephen Scullion’s experience as an Olympic marathoner, 2:09 runner and coach — not generic training templates.
Follows your fitness profile
Your zones, strengths, weaknesses, race readiness and training response update as your data changes.
Helps you execute the session properly
RunZones scores sessions against their intended purpose — LT1 control, LT2 threshold, aerobic power, VO2, long-run durability or marathon-specific work.
Turns history into direction
The system looks at what made you fit before, compares it with where you are now, and shows what needs to happen next.
Execution
Not just what to run. How to run it.
A good plan only works if the athlete executes the right intensity. RunZones helps you understand the purpose of each session, the correct zone, the right effort — and whether you actually hit the target.
5 × 1 km threshold
Purpose: build LT2 control without turning the session into a race.
Strong pace control. Keep recoveries honest and avoid pushing the final rep too hard — this is a platform session, not a race.
Too fast early. The session drifted from threshold into VO2 stress — more fatigue, wrong training effect.
Controlled start. Stable HR. Correct zone held to the last rep — better training effect, less cost.
RunZones scores every session against its intended purpose, so each run becomes feedback — not just a box ticked.
Turn every session into feedback →Your fitness profile
Your profile changes with every run.
RunZones tracks more than pace. It follows your aerobic base, threshold control, VO2 exposure, durability, execution quality, fatigue signals and race readiness.
Attribute profile
Every completed session updates the profile — so the plan follows the athlete, rather than forcing the athlete to follow a static plan.
Race recipe
Find the recipe behind your best races.
Your best performances leave clues: the volume you handled, the sessions you repeated, the long runs that mattered, the threshold work that moved you forward, and the taper that left you ready. RunZones finds what worked — then compares it with your current build.

- Readiness improving
The intelligence behind the system
Stephen’s intelligence powers it. The analysis is about you.
We don’t copy Stephen’s training onto you. We use proven elite patterns to teach the system how to think — then scale the plan to your physiology, history and goal.
