Winning silver at the 2012 Olympics stands out as Bithell's most memorable sporting achievement. His father has been the most influential person in his career, providing guidance and support. Bithell also looks up to British cyclist Bradley Wiggins as his hero.
In 2013, Bithell sustained an ankle injury that hindered his training during the northern hemisphere summer. This setback was a significant challenge, but he managed to overcome it with determination and resilience.
Bithell's sporting philosophy is simple yet profound: "Make sure you keep it fun and enjoy every moment." This motto reflects his approach to both training and competition, emphasising the importance of enjoyment in sports.
In 2009, Bithell began competing with Luke Patience in the 470 class. The duo won silver at the 2012 Olympics before parting ways. Bithell then switched to the 49er class, initially racing with Chris Grube for a year before teaming up with John Pink in early 2014.
Transitioning from crewing a 470 to helming a 49er was challenging for Bithell. His ankle injury further complicated this transition, leading him to return to crewing. Despite the difficulties, he made this decision without regrets.
Looking ahead, Bithell aims to become one of the few crews to have won medals at the Olympic Games in different disciplines. This ambitious goal reflects his dedication to continuous improvement and excellence in sailing.
