Elevate Your Training with VO2 Max and Lactate Threshold testing
Unlock your potential with ONE LDN’s Performance Tests — including V02 Max, Lactate Threshold and Combined Testing - built for anyone serious about real progress and long-term performance.
Whether you’re chasing a faster 5K, hoping to shave minutes off your HYROX time, or training for overall health and longevity, our VO2 Max and Lactate Threshold tests provide the insight you need to train smarter—not harder.
Get personalised metrics. Performance Testing at ONE LDN means no more guesswork—just clear, personalised metrics that show how efficiently your body uses oxygen and the exact point where fatigue kicks in.
The result? Smarter programming. Better sessions. Measurable progress.

This test gives you lab-grade data to guide your training. VO2 Max measures your aerobic capacity — your body's ability to take in and use oxygen efficiently.
Lactate Threshold identifies the exact point where your body shifts from sustainable effort to fatigue buildup.
Understanding these two metrics is the key to structured endurance training — especially for events like HYROX, where pacing, efficiency, and recovery all matter.
-
Trainers and clothes suitable for high-intensity exercise
A water bottle
Any recent race times or training benchmarks
-
void strenuous activity for 24 hours prior to your test
Arrive 10 minutes early to allow time to check in

-
We’ll follow, on email, after your test with a personalised report of your VO2 Max and Lactate Threshold zones. This will include your target training paces and intensities.
You’ll also receive one month of free access to the Unbeatable Academy — our hybrid training program designed to improve performance and prep you for your next race.
VO2 MAX TESTING
VO2 Max testing measures your body’s peak ability to use oxygen during intense exercise — it’s the gold standard for assessing cardiovascular fitness.
It’s a powerful look under the hood of your performance engine — revealing your aerobic capacity, endurance potential, and how efficiently your body turns effort into results.
Lactate threshold testing
Your Lactate Threshold is the point where your body starts to fatigue faster than it can recover — and knowing exactly where that line is helps you train right on it, pushing performance without burning out.
During the test, we track your blood lactate levels as exercise intensity increases. This gives us precise insight into your optimal training zones.
COMBINED testing
Take your training to the next level with lab-grade performance testing. By combining VO2 Max and Lactate Threshold assessments, you’ll get a complete view of the exact pace zones you should train in.
These insights directly shape your run intervals, recovery, and conditioning intensity - helping you focus your effort where it actually counts.
