Girona Lab
Performance testing, ErgoFiT bike fitting and endurance coaching — in the cycling capital of Europe, since 2020.
Street-level lab in the heart of Girona
Established in 2020 by John Wakefield, S2S Girona is a dedicated performance science facility located in the centre of Girona — a city that has become home to hundreds of professional and elite cyclists from across the WorldTour and beyond.
The lab provides metabolic performance testing, ErgoFiT bike fitting and endurance coaching using the same protocols that underpin S2S's work at the highest levels of professional road cycling. Running testing is also available, with Girona's proximity to the Banyoles triathlon hub making it a natural choice for multisport athletes.
Where every wall tells a story
The S2S Girona lab is lined with race jerseys, signed numbers and memorabilia from the athletes who have come through its doors — Tour de France yellow jerseys, World Championship rainbow stripes, Grand Tour podium kits. It is a working reminder of the level at which the coaches here operate daily.
"For John — you made this possible. Thanks a lot."
— Nico Denz, Red Bull–BORA–hansgrohe, Giro d'Italia stage winner
Cycling Performance Tests
Each test is conducted on your own bike on our calibrated ergometer. Height, weight and body composition are recorded at every session.
VO₂ Max Test
90 minMaximal oxygen uptake (VO₂ Max), peak power output (PPO) and metabolic thresholds are strongly associated with endurance performance and can be used to quantify training adaptations. After a self-paced warm up, the test increases at a constant rate until exhaustion.
Fat Max Test
90 minTraining at the correct intensity ensures the majority of energy is derived from fat. The Fat Max test determines the zone where fat oxidation rates are maximal — a key metric for endurance and body composition goals.
Lactate Accumulation Test (LAA)
90 minThe LAA determines the training intensity at which lactate rises above baseline but remains sustainable for prolonged durations. Targeting this zone can produce a positive shift in your lactate curve.
Complete Metabolic Profile
90 minA combined Fat Max and LAA assessment. Determines whether your training interventions have been successful and defines the precise intensities targeting both fat oxidation and carbohydrate pathways.
Complete Metabolic Profile / VO₂ Max Combo
90 minOur most comprehensive cycling performance assessment. A full Metabolic Profile followed by the VO₂ Max test after a short recovery break. Provides a complete picture of your performance physiology.
- VO₂ Max & peak power output
- Fat oxidation zones (Fat Max)
- Lactate threshold & training zones
- Metabolic efficiency at each intensity
- Carbohydrate vs fat contribution curves
- Detailed PDF report with zone prescriptions
Running Performance Tests
Treadmill-based running tests conducted with gas-exchange monitoring. The same evidence-based protocols as cycling, adapted for running physiology.
PTS / VO₂ Max Test
80 minVO₂ Max, peak running speed (PRS) and metabolic thresholds are strongly linked to running performance and are reliable markers for tracking training adaptations. An incremental treadmill test to exhaustion with full gas-exchange recording.
Fat Max Test
80 minDetermines the running intensity at which fat oxidation is maximal. Critical for marathon, ultra-endurance and Ironman athletes targeting optimal fuelling strategy and body composition adaptations.
Lactate Accumulation Test
80 minDefines the running pace at which lactate remains sustainably elevated — the key target zone for threshold training. A positive shift in the lactate curve is the hallmark of improved aerobic fitness.
Complete Metabolic Profile
90 minThe full running metabolic assessment. Combines Fat Max and LAA protocols on the treadmill to define your optimal training zones for both fat oxidation and threshold adaptation.
Complete Profile / PTS / VO₂ Max Combo
90 minOur most comprehensive running assessment — a complete Metabolic Profile followed by the Peak Run Speed / VO₂ Max test. Full picture of running performance physiology in a single session.
- VO₂ Max & peak treadmill speed
- Fat oxidation zones
- Lactate threshold & training zones
- Detailed PDF report with zone prescriptions

Medical Fit
120 minThese consultations include an assessment of injuries and unique intrinsic factors that may have contributed to the injury, as well as prescribed exercises and stretching. Using principles incorporated in the Professional Fit, your bike fit is comprehensively evaluated. A portion of this consultation can be claimed from medical aid.
- Full Professional Fit protocol
- Injury & intrinsic factor assessment
- Prescribed exercises & stretching
- Clinician-supervised throughout
- Portion claimable from medical aid
Strength & Body Composition
Targeted assessment of strength, movement quality and body composition — to guide training, track adaptation, and reduce injury risk.
Skinfolds
20 minSkinfold measurements estimate body-fat percentage by measuring subcutaneous fat thickness at standardised anatomical sites with callipers, entered into validated equations to estimate body composition.
S&C Assessment
60 minA strength and conditioning assessment evaluates physical capacity, movement quality and neuromuscular function to identify strengths, weaknesses and injury risk, guiding an individualised training programme.
Gym Use
60 minPurchase a pack of 10 entries to our on site gym, where you can enjoy pre-arranged private access.

What our clients say
Bike fit and performance testing reviews from clients at the Girona lab.
I travelled from France on 16 March 2026 after reading some great reviews, I was not disappointed. I was greeted by Darrel Fitz-Gerald & Felix Imbery. I was put at ease instantly and received professional advice throughout my session. When I arrived back home they had already emailed me some stretching exercises they thought I would benefit from. I would recommend anyone who needs advice and a fitting to put this company at the top of your list.
GoogleExcellent bike fit service from Teresa, Felix and Darrel. I have had two bike fits with other providers in the past but this session still gave me a significantly better bike setup and understanding of my physical needs, including recommended stretching exercises. Bike fits are probably the most valuable thing any rider can invest in, and this is a great value service
GoogleWorking with John and Darrel from Science to Sport was amazing. The bike fit they did for me has been truly spectacular. I used to have several aches after long rides and thought it was just from spending so many hours on the bike. After the fit, riding has been a completely different experience.
GoogleSo pleased I made the decision to go here. Darrel and Matt were incredibly welcoming. The level of detail and explanation was superb. I had not had a fit for over ten years and wanted to check some issues on new bikes. From saddles, to cleats and the bike itself, we covered everything. A few tweaks here and there, a spacer on one pedal to align my leg = a much better position and riding.
GoogleI was suffering from terrible pain in my groin, and my left hand and left foot would go numb. I did the bike fit on both my road and gravel bikes, and since then, my rides have been a completely different experience. It was totally worth it, thanks for everything!
GoogleOutstanding service and value. True professionals. It sometimes surprises me how cyclists are willing to spend any money on a bike, but would often neglect the one thing that'll maximise the enjoyment on that bike: a bike fit from an experienced professional. Pressure mapping was a game changer for me. Don't wait if you're not feeling 100%. Give John and the boys a shout.
GoogleLove this place. Immaculate attention to detail, John and Daz really listen to your concerns and work with you to achieve the best bike fit. I have also been for testing, and receive excellent feedback and advice moving forward.
GoogleAfter nearly a decade of on-and-off fit issues and more bike fits than I can count, I'd reached the classic point of solve one problem, create another. Then Darrell and Science to Sport stepped in. From the moment you walk in you can tell they're the real deal — no nonsense or salesy BS. He explained every adjustment and the reasoning behind it, and his understanding of anatomy and athletes goes way beyond blindly following a fitting system.
GoogleI moved to Spain to enjoy my retirement, exploring the region on my bicycle. Custom doesn't necessarily mean it fits correctly. After experiencing some nerve issues I sought out the advice of Science to Sport. They listened to my concerns, explained why I might be experiencing them, made some changes and double-checked them. I can say that the changes made were transformative — I continue gravel riding, with great intensity, pain free.
