Whitehead will be 40 years old by the time the Paralympic Games come around, but the three-time world champion is only getting quicker as Rio closes in. At 35, Whitehead won his first world title, which quickly followed by European and Paralympic gold in 2012.
The sprinter then went on to retain his world title, before embarking on a charity expedition, which saw him run 40 marathons in 40 days and in doing so becoming the first double leg amputee to run the length of the country.
Whitehead had a minor setback when he finished in the silver medal position in Swansea in 2014, but quickly returned to winning ways breaking the world record on his way to another world title in Doha.
In 2016, Whitehead showed that he could well be a major threat in the 100m as he won both sprint events in Grosseto as he warms up for what is likely to be his last Paralympic Games.
