Walcott faced significant injuries throughout his career. He underwent two elbow surgeries in 2017 and dealt with an ankle injury from the 2013 Diamond League event in Doha, Qatar. These setbacks required him to cut his 2018 season short for full recovery.
Walcott's career is decorated with numerous accolades. He won gold at the 2012 Junior World Championships in Barcelona and the 2012 Olympic Games in London. This made him the first athlete to win gold in the same event at both competitions in the same year.
He was named Senior Male Athlete of the Year by the National Association of Athletics Administrations (NAAA) in Trinidad and Tobago in 2012 and 2014. Additionally, he received the Sportsman of the Year award from the Trinidad and Tobago Olympic Committee (TTOC) in those same years.
In 2019, Walcott was honoured as the Most Outstanding Athlete in the men's field category by the NAAA. His contributions to sport earned him the Order of the Republic of Trinidad and Tobago in 2012.
Walcott's sporting philosophy reflects his resilience. He believes that criticism is a constant companion for athletes. "You have to learn to deal with it," he says. Despite winning a gold medal at the 2012 Olympics, he faced comments about his throwing distance.
His older brother Elton also competed internationally, placing ninth in the triple jump at the 2015 Pan American Games in Toronto, Canada.
Looking ahead, Walcott aims to compete at future Olympic Games. His dedication to javelin continues to drive him forward despite past injuries and challenges.
Walcott's success has had a significant impact on Trinidad and Tobago. Following his gold medal win at the 2012 Olympics, August 13 was declared a national holiday. A Caribbean Airlines aircraft, a housing development, and a lighthouse were named in his honour.
