Who are we?

FLYCARB was founded in 2024 by Josh Elston-Carr and Jack Gray, two athletes who started their journey in grassroots running and have never forgotten their origins. We believe that no matter how fast you are, pushing your personal limits—whether on the track, road, trails or cross-country—is what truly matters.
Jack Gray

Jack is a classic ‘club man’ who loves representing his club, Cambridge and Coleridge AC. He has run 28:27 for 10km and has represented Team GB and England in cross-country, track, and road running.

Jack Gray
Josh Elston-Carr

Josh is a sub-4 mile and a sub-8 3k runner who also enjoys competing on the road and cross-country for Cambridge and Coleridge AC. He has had the honour of representing England in the road mile.

Joshua Elston-Carr

Together, they combined their expertise and experiences to create a product for athletes who, like them, are always striving to beat their best. As business owners, they pride themselves on being diligent, thorough, and committed to innovation. Jack has a BSc and Master of Research from the University of Birmingham, while Josh is a Cambridge University graduate in Engineering.
