Getting a proper lab-based VO2 Max test used to mean leaving St Helens for a university sports-science lab in Liverpool or Manchester, with a waiting list and city-centre parking on top. TELOMYX brings a mobile metabolic testing unit directly to Evolution Fitness XL in West Park, with on-site parking and easy access from across the borough, plus the option to come to your gym or running club anywhere in St Helens.
We measure the oxygen and carbon dioxide in every breath with a clinical metabolic analyser, the same method used in sports-science labs. Not a wrist-based estimate from a watch. Our St Helens unit is at Evolution Fitness XL, West Park (WA10 3TF) — on-site parking, minutes from the town centre, no drive to a university lab in Liverpool or Manchester.
Within 48 hours of your test, with your VO2 Max, ventilatory thresholds and training heart-rate zones. Not a single number you can't act on.
Your report converts the raw data into the exact heart-rate zones to train in, so every session has a purpose instead of guesswork.
Clinically led from day one. No supplements, no transformations, no upsells. Just the data and what it means.
Recent reviews from clients who had a VO2 Max test at our St Helens venue. Verified via Google Business Profile.
★★★★★
"Did the VO2 Max about eight weeks before the St Helens 10K. I'd always paced on feel and faded badly in the back half. The test showed my easy runs were basically tempo efforts. Trained to the zones instead and ran a proper negative split for the first time."
★★★★★
"Ride with a club around the lanes near Billinge and Rainford and wanted real threshold numbers rather than estimates off my head unit. The report was clear and the team explained exactly how to set my power and heart-rate zones. My interval sessions actually mean something now."
★★★★★
"Booked it as a health check in my mid-forties more than anything. My watch number was in the right ballpark but the report gave me actual training zones and a clear explanation of what the thresholds mean. Glad I could do it here in St Helens rather than trekking out."
Six things every St Helens VO2 Max client gets, as standard.
The maximum volume of oxygen your body can use per kilo per minute, the single best lab measure of aerobic fitness and a strong predictor of long-term health. Measured by lab-grade metabolic cart at Evolution Fitness XL, West Park, St Helens (WA10 3TF).
Your true training zones based on measured ventilatory thresholds, not the generic age-based formula your watch uses.
How your body switches between burning fat and carbohydrate as intensity rises, useful for endurance fuelling and body-composition goals.
Emailed within 48 hours with your full data set and reference ranges. Share it with your coach, club or GP.
Alongside your report, a member of the TELOMYX team will give you specific recommendations based on your own biology and results, so you know exactly how to train, not just what your number is.
The test itself is around 20 minutes of progressive effort to exhaustion. From walking into Evolution Fitness XL to walking back out, plan for about an hour. More on VO2 Max →

No. Unlike DEXA, a VO2 Max test involves no radiation and needs no medical referral, so you can book directly online. If you have a known heart condition or your doctor has advised caution with maximal exercise, let us know in advance and we'll confirm suitability before your appointment.
A lab test directly measures the oxygen and carbon dioxide in your breath as you exercise, which is the gold-standard method. Watches and fitness trackers estimate VO2 Max from heart rate and pace using an algorithm, and can be off by 10–15% or more. If you want a number you can actually base your training zones on, a measured lab test is the only reliable option.
The test itself is around 20 minutes of progressive effort. Including set-up, warm-up, the test and your results walkthrough, plan for about 60 minutes at Evolution Fitness XL, West Park. On-site parking is available. Your full medical PDF report follows by email within 48 hours.
A VO2 Max test is a maximal effort, so the final couple of minutes are genuinely hard. The protocol starts easy and the intensity steps up gradually, and a member of the TELOMYX team is with you the whole time. You stay in full control and can stop at any point. Most people are surprised that the build-up makes the hardest part feel manageable.
VO2 Max is measured in millilitres of oxygen per kilogram of body weight per minute (ml/kg/min) and depends heavily on age and sex. A typical untrained adult might sit in the low-to-mid 30s, a regular recreational runner in the 40s, and a competitive endurance athlete in the 50s or 60s. Your report includes age- and sex-matched reference ranges so you can see exactly where you sit.
A standalone VO2 Max test is £150. Multi-test bundles combining VO2 Max with DEXA and RMR offer the biggest savings, see our bundles page.
Most clients re-test every 6–12 months, or before and after a major training block. Runners preparing for the St Helens 10K or a half marathon often test at the start of a block to set zones and again afterwards to confirm the gains.
As you exercise harder, your body passes through two key tipping points: the first ventilatory threshold (where you shift from mostly easy aerobic effort) and the second (where lactate accumulates faster than you can clear it). These thresholds define your real training zones. Training relative to your measured thresholds, rather than a generic age-based heart-rate formula, is what makes each session count.
Wear normal gym kit and trainers you'd run in. Avoid a heavy meal in the two to three hours before, avoid caffeine and alcohol on the day, and don't do a hard training session immediately beforehand. Your confirmation email includes the full pre-test guidelines, and following them gives you the cleanest, most accurate result.
Our standard St Helens protocol is treadmill-based, which suits runners and general fitness clients best. If you're a cyclist or triathlete and would prefer a cycle-specific protocol, get in touch before booking and we'll let you know what we can arrange at your venue.
No. While serious runners and cyclists use it to fine-tune training, VO2 Max is also one of the strongest single predictors of long-term health and longevity. Plenty of our St Helens clients book it simply to get an honest baseline of their cardiovascular fitness in their 40s, 50s and beyond, and to track it over time.
A VO2 Max test measures your aerobic capacity and metabolic thresholds. It does not measure your body composition (that's DEXA), your resting calorie burn (that's RMR), your muscular strength, or your blood markers. It answers one question precisely: how much oxygen your body can use under load. Many clients pair it with DEXA and RMR for the full picture.
