  • Hi Garth
    Many thanks for a truly memorable weekend. The training, teaching and experience was fantastic: I was still reliving some of those climbs on the plane home! It was also great to meet your lovely family.
    Thank you again and I can’t wait to get back down for another weekend of precision training.

  • I was fairly new to cycling. I loved it, but felt like I had reached a plateau - I was suffering from frequent illness and injury, I didn't see much reward out for the extra effort in, and consequently my motivation was starting to falter. By good fortune, the gurus at Cyclefit recommended Garth Fox - and I haven't looked back since.

  • My goal after having two children was to get back to at least the level of 10k running performance I was at before having children, which was 50 mins. Under Garth's highly professional guidance I recently managed a time of 45 mins and came 6th in my age group! I am ecstatic and have already set my sights on a triathlon next year. As Garth always tells me, the limits are only where you set them. Thankyou!

  • Garth's enthusiasm for endurance sports physiology seemingly knows no bounds. He has a great understanding of the human body and how it responds to rest and training. He's also one of those rare people who have both communication and analytical skills, when most people only have one or the other.

    Phil Mosley - Elite Triathlete & Coaching Editor of Triathlon Plus magazine

  • Garth really knows how to connect the dots between training and performance. His enormous expertise in physiology and sports science makes his training interventions very perceptive and his ability to tease out the precise adaptations required for the desired improvement in performance with different training stimuli is uncanny.
