Coaching Staff

Guy Worrow

Director of Swimming


Age Group Performance 1 Lead Coach




Guy began his coaching career as a development coach at Enderby Swimming Club in 2006. A successful swimmer himself, holding multiple county and regional records and racing in numerous National Age Group, Youth and Senior finals, Guy brought a lot of knowledge to the table. He quickly moved up to be their Director of Swimming and then successfully spearheaded the merger of Enderby SC with Lutterworth SC in August 2011. Since the merger in 2011, Guy has directed and guided the club team, which started with 23 hours of pool time, and just over 200 athletes, to a fully formed 300+ member Development Programme. This Programme can now offer it's athletes 44 hours of pool time and the opportunity to develop from the first strokes out of learn to swim, all the way through to National level competitions.

Since Leicester Shark's inception, Guy has coached athletes from their first competitions, through county championships and onto Regional and National finals. In 2016, he developed his young athletes to a point where he coached a swimmer to two National medals and a place on the second phase of the National Pathway Programme. He has consistently coached Regional Champions every year since 2014, as well as multiple Regional medalists and finalists.

Under his charge, The Junior League team at Leicester Sharks CSC have made the regional final for each of the last 6 years, qualifying for the semi final for the last 3 years, and racing the other top 8 teams in the country in the National Final in 2017. This team has gone from strength to strength under his guidance and really shows the attention to detail our young athletes are handed when they first join the club. There has been a similar improvement as those athletes have filtered through into our Senior Arena League team, with the team qualifying for the area final for the last two years, narrowly missing out on qualification for the National Final in 2017, as they finished in 3rd place.

Guy has always been ambitious and his dedication and determination to push this club forward continues to have a positive impact on our members and ensure we have a lot to look forward to at Leicester Sharks CSC in the future.
