Comprehensive Running Assessment for Marathoners & Triathletes
Stop guessing your pace. Our advanced VO₂ max, running economy, and biomechanical testing reveal how your body actually produces energy — helping you train at the right intensities, fuel more efficiently, and perform at your full potential.
Whether you’re chasing a marathon PB or preparing for your next Ironman, this assessment uncovers what’s holding you back — and gives you a clear, data-driven roadmap to move forward with confidence.
WHAT you’ll gain
Discover your Endurance potential
Our Endurance running assessment is a comprehensive package aimed at marathon runners, Ultra runners and long distance triathletes. The assessment will give you a 360 degree view of all aspects of your running physiology and running form and allow you to maximise your training to achieve your goals!
Realistic Race Pace Targets
Find out exactly what pace your body can sustain — not just what you hope for. We analyse your VO₂ max, aerobic & anaerobic thresholds and running economy to give you precise, meaningful targets.Tailored Training Focus
Whether your limiter is technique, aerobic efficiency or fuelling, we pinpoint it. Then we show you how to bridge the gap between where you are now and where you want to be.Fuel & Substrate Insights
Understand how your body uses fat and carbohydrate at race intensities, and develop a race-day fuel strategy that works for you.Injury Risk Reduction (with optional biomechanical analysis)
Add gait and movement screening to highlight technical inefficiencies or movement patterns that may lead to injury — and get drills to correct them.Early-Season Benchmarking
Get tested at the start of your training block is build around real data — not guesswork.

WHAT TO EXPECT
How the test works
1. Initial Discussion
We’ll talk through your running history, training routine and race goals — whether you’re going after a marathon, ultra or Ironman-70.3. This ensures the session is focused on your needs.
2. Two-Part Testing Protocol
VO₂ Max & Threshold Test
A progressive treadmill ramp test to determine your true aerobic capacity and thresholds.
Running Economy & Fuel Efficiency Test
After a brief recovery you’ll run intervals around your target pace while we measure oxygen, movement and substrate use.
(If selected) Biomechanical Gait Analysis: We capture high-speed video of your run to spot asymmetries, sub-optimal stride patterns, ground-contact time inefficiencies, etc..
3. Debrief & Report
You’ll leave with a comprehensive report that explains your results clearly, gives your training zones, pacing strategy and any technique or fuelling tweaks you need.
4. Action Plan
If you choose the “Plan” package, we’ll deliver a 12-week personalised training plan built around your data so each session has purpose and is aligned to your race goal.
How you’ll use the data
Testing is just the start — what really matters is how you apply the insights.
After your assessment, you’ll receive a detailed report and debrief that highlight the key takeaways and show you exactly how to use the data in your training.
Here’s what you’ll walk away with:
Precise Training zones
Your VO₂ max and threshold data will give you clear heart rate, pace, zones tailored to your physiology. You’ll know exactly how hard to train on easy, steady, tempo, and interval days.
Realistic Race Pace Guideance
Based on your current fitness and running economy, we’ll help you understand what pace you can realistically sustain over marathon, half-marathon, or Ironman distances — helping you avoid early blow-ups and negative splits gone wrong.
Fuelling Strategy That Works for You
Learn how your body uses fat vs carbohydrate at different intensities, and get practical advice on what, when, and how much to eat during long training runs and race day.
Biomechanical Data (if added)
If you’ve selected the biomechanical analysis, we’ll provide detailed insights into your running technique. This includes:
Video analysis of your stride, foot strike, posture, and arm swing
Sensor-based data on symmetry, and movement patterns
Identification of inefficiencies or imbalances that could impact performance or lead to injury
You’ll get movement-specific advice, drills, and technique tips to help you run more efficiently and reduce injury risk — especially useful as training volume increases.
Targeted Areas for improvement
We’ll highlight exactly where you’re most limited, whether that’s endurance, lactate clearance, technique, or energy efficiency and provide practical suggestions to address those areas in training.
The comprehensive report explains everything to take you from where you are now to where you are trying to get to.
A Smarter Training Plan
If you choose the training plan package, we’ll use your test data to create a 12-week plan designed around your goals and physiology. Every session will have a purpose — whether that’s building endurance, increasing speed, or improving fatigue resistance.

“Had a Vo2 Max and running gait assessment done to support my training and also injury prevention. Absolutely brilliant service from Kev, through explanations, suggestions and detailed report to refer to and help progress. Would gladly recommend and i will return for re-assessment once put the plans and changes in place”

FAQ
Quick Answers
-
It’s ideal for any endurance athlete — marathon runners, triathletes, ultra-runners, or anyone training for a long-distance event — who wants to understand their physiology, improve their performance, and train smarter.
-
We recommend testing early in your training block 12 to 16 weeks before race day. If training for a marathon, at the start of your training is optimal.
This allows you to tailor your training based on accurate data and track meaningful progress toward your event goals.
-
You’ll discover your VO₂ max, aerobic and anaerobic thresholds, fuel usage (carbohydrates vs fat), running economy, and (if chosen) biomechanics. You'll also receive practical pacing guidance, training zones, and nutritional advice tailored to your race.
-
Not at all. We work with a wide range of runners from first-time marathoners to Kona qualifiers. If you're committed to improving, you’ll benefit from knowing where you are and how to get where you want to be.
-
Bring your usual run kit, suitable shoes, and a water bottle. The test is done indoors on a treadmill. If you're doing the biomechanical analysis, snug clothing helps with accurate motion capture.
-
Try to avoid intense training the day before, stay well hydrated, and eat a normal light meal 2–3 hours before. We'll send you full pre-test instructions upon booking.
-
The full assessment takes about 90 minutes. This includes discussion, warm-up, VO₂ testing, economy stages, optional biomechanical analysis, and a post-test review of your results.
-
Absolutely. You'll receive a detailed PDF report with all your physiological data, along with clear explanations and recommendations that can be used by any coach or training platform. We are more than happy to discuss the findings with other coaches and share knowledge.
-
Yes you can add a fully personalised 12-week plan based on your testing.
