About

Sub3fitness owner David McKenzie was a talented young athlete. Brought up in South London with a brother who was a southern area boxing champion, the competitive spirit was instilled within him from a young age. 

During The European Championships, McKenzie would garner the inspiration for his company Sub3fitness that epitomises the values that David stands by that are accomplishment, hard work determination, inspiration and desire. These principles are required to succeed at sport and in life.

McKenzie’s relay team comprised of Brian Whittle, Roger Black and Duaine Ladejo ran a world leading time, running under 3 mins and entering the sub3 club. Rings were given to each member of the team for this special achievement.
