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.
Coaches & Scientists at Girona
S2S Girona is led by resident coaches with doctoral qualifications and experience at the highest levels of professional cycling, triathlon and multisport.

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.
