Alex Heron did not begin his triathlon career until he was 64. Now, the 74-year-old is hoping to complete the Ironman Wales - something that nobody in his age category has ever done before.
The athlete has reached the podium in four previous triathlon events for his age group, placing second in two events and third in two others. Now, the grandfather is set to take on his biggest challenge yet - Ironman Wales. Despite having always said he would never do a full Ironman, Alex is now hoping to be the first ever to complete the event in the 75-79 age category.
The gruelling event kicks off with a sea swim of 3.8km, followed by a 180km cycle race and ending with a full 42km marathon run. Thousands of athletes from all over the world descend upon Tenby every year in an attempt to complete the challenge within a tough 17-hour time-frame.
