Really proud of the feedback coming through from this year’s marathon group 🏁
The goal was never just getting people to the finish line it was making sure they arrived confident, prepared, and trusting the work they’d put in over the months leading up to race day.
Seeing athletes grow in confidence week by week and achieve results they’re proud of is what it’s all about 👏
More testimonials still coming in 🙌

London Marathon 2026.
Proud of this lot, my first trial group and the athletes I coach. Not always the times we want the Marathon is such a beast!!
A lot of work went into this block. Early mornings, consistency, just getting it done week after week.
A few niggles along the way but we managed them and got to the start line.
Everyone turned up and put a proper shift in. Some unbelievable results across the group.
That’s what it’s about.
Berlin next.
