Since we started the podcast, I've introduced many of the UK triathlon legends, ranging from our Olympic champions to coaches who helped them there, and the folks who were around right at the start of triathlon in the UK.
Today's guest, Mark Kleanthous, competed in UK triathlons since the very first event in June 1983. And he has kept on going for 41 consecutive years.
Completing an impressive 535 triathlons in more than 20 countries, including finishing the Hawaii Ironman World Championships, as well as 48 Iron distance, double Iron, and 1 x triple Iron triathlon.
Mark has also finished 71 marathons under 3 hours.
Over the last 41 triathlon seasons Mark has calculated that he's covered more than 12,000 miles swimming, 198,000 miles cycling, and has run more than 61,000 miles (totalling 271,000 miles) in training and racing. That's more than 11 times the distance around the world, or more than the distance to the moon! 
In this conversation we chat about:
Keeping calm under stress, and problem solving
How he still gets satisfaction from each event
Why pacing gets better with age
The secret to Mark’s athletic resilience and longevity
Mark the Innovator - homemade elastic laces & aero water bottles
