Over six months after performing the magnificent achievement of bouncing 16km (10 miles) on a space hopper around the Kip Keino Athletic Stadium Martin receives the certificate to prove the achievement to the world.
Martin Mienczakowski took on the challenge to raise money for the Stroke Association after being a victim of a stroke himself.
Using our 66cm Retro Black Space Hopper he smashed the previous record of just 8km (5 miles).

Martin was kind enough to send us a copy of the certificate that sits pride of place on one of our office walls.
