Laurence, 29, was athletic from his childhood and competed in triathlons. He was the British Triathlon regional champion for the 13-14 age group.
However, in 2006, when he was just 14, he was diagnosed with osteosarcoma, a form of bone cancer, below his right knee and doctors told him he only had a 30 per cent chance of surviving the illness.
He had surgery to take out the tumour, which meant that his knee joint and part of his fibula were removed. He also had a further procedure to replace the joint and insert titanium rods into his leg.
After 11 months of chemotherapy, he underwent a year of physiotherapy and had to learn to walk again.
Patience is a virtue
Once he fully recovered, Whiteley originally competed as a swimmer and went on to become a national junior champion at 50m freestyle in the S10 category.
In 2011, he was drawn to rowing and began competing in the non-Paralympic trunk-arms men’s single scull category at the Tees Rowing Club. He has trained with the national group in Caversham, Berkshire, since the year 2014.
He spent more than two years trying to find a partner to compete in the Paralympic double sculls with and finally found Lauren Rowles, a former wheelchair racer who had recently turned to rowing, in the early months of 2015.
They won a silver medal at their first major championship together, the 2015 World Rowing Championships in the TAMix2x trunk-arms mixed double sculls.
They went on to win gold in the final of the heats at the 2016 Summer Paralympics in Rio, where they set a world record.
