Runner pushing the age barriers with CurraNZ in the London Marathon

It's with pride and admiration that we share the remarkable story of CurraNZ fan Mark Kleanthous, one of Britain’s fittest 60-year-olds with over 280,000 miles and 100+ marathons under his belt.

Forty-two years after running in the inaugural London Marathon (pictured, above), Mark once again took to the streets of the capital last month to participate in this iconic event, with the ambition of running as fast as he did 42 years ago.

Mark has finished 71 of those marathons in less than 3 hours, with a personal best time of 2:24:40 (when 112nd overall in the London Marathon).

In the last ten years, he has been using CurraNZ to delay the decline in aging and supporting his recovery from his relentless love of training and racing.

Mark, from Leighton Buzzard, has competed in 1,100 events worldwide across a variety of endurance disciplines involving swimming, biking and running.

In the last 44 years Mark has covered almost 280,000 miles (986,000 kilometres) in training and racing, equivalent to going around the earth more than 11 times.

The fitness afficionado and coach has pounded out more than 14,000 miles swimming, 201,000 miles cycling and 65,000 miles of running and credits CurraNZ for helping him cope with the demands of training and racing in his 60s.

After discovering the supplement almost a decade ago, Mark says: “CurraNZ has not powered me for all those miles/kilometres, but it’s certainly making my third trip to the moon much easier on my aging 62-year-old body.

This will also be Mark's 42^nd year competing in triathlons (1983-2024), a feat that no other Briton has achieved. He raced at the World Ironman Championships twice, in 1987 and 2010.

With endurance sport becoming more and more extreme over the years, Mark has risen to the challenge, first with a double Ironman (which he completed in under 24 hours), then a Triple Ironman in France, which took him 45 hours and 58 minutes.

We congratulate Mark for his age-defying success and wish him all the best this season.
