Coaching Team

Guy Worrow

Director of Swimming


Age Group Performance Lead Coach

Development Performance 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.

Age Group Potential Lead Coach

Learn to Swim Lead Coach




Back in 2009, when my son was swimming with Enderby Swimming Club, I was watching one of his sessions when I was asked if I fancied helping out on poolside. I'm game for anything, so I thought, let's give this a whirl.
Over the next 7 years, I qualified as a level 2 teacher and coach, and was mentored by Guy Worrow. I continued coaching with Enderby swimming club, through it's amalgamation with Lutterworth SC as they became Leicester Sharks CSC. As Brand Manager at the time, I was proud to have designed the Leicester Sharks logo, which has become well recognised on our banners and hats to this day.
After successfully assisting and leading the Development side of the club for many years, I am now lead coach to our Learn to Swim programme, and our Age Group Potential Programme. I love being there at the very start of a swimmer's journey into this amazing sport, and seeing their eyes light up as they get make every single step forward in their swimming ability. Our Age Group Potential Programme is filled with athletes who love their sport. It's such a joy to coach this group, who week in week out continue to push for improvement and enjoy their swimming.

Development Potential Lead Coach

Adult Swim Lead Coach





I was an average swimmer for a couple of years before my teens then revisited swimming, mainly in the form of triathlons, whilst in the army. Again left swimming only to return to masters swimming and more lately Leicester Sharks when my two children started with the club in 2012. I took up coaching when they joined Sharks and progressed through my qualifications. Both my children swam in the group which is now called Development Potential and I am continually humbled to see swimmers progress through the squad.

Lead Coach


Pups Lutterworth Lead Coach





I first became involved with swimming through my two daughters, who originally swam for Lutterworth SC and after megring with Enderby SC to form Leicester Sharks, my youngest progressed so well that she won the silver medal at the Midlands Championships in 200m Butterfly, and came 6th in the Open Water National final. My eldest daughter trained with Lutterworth and then Sharks until she turned 18 and now coaches alongside me with the Pups squad.

During this time, I have qualified as a Level 1 & 2 Swimming Teacher and continue to coach the Pups squad with my eldest daughter who has now attained her Level 1 qualification.
My sporting history was in the game of flat green bowls, where I started at Lutterworth Bowls Club at the age of 13 and then moving to Narborough Bowls Club where I continued into my 40's. In this time, I won competitions as an individual and team member at both club and county level, with this success, I represented Leicestershire Bowls at Junior and Senior level indoors and outdoors. My highlight was having an England trial at Junior level.
After finishing playing bowls, my focus was, and is, with Leicester Sharks. It is always a great joy for us coaches seeing the progression of our young swimmers to the next level.
