ISS Swimming program just keeps getting better....

Competitive swimming training alongside a demanding academic curriculum take, not only huge dedication, but also physical and mental strength from our young athletes, some of whom train up to a dozen times per week.

We are always congratulated as a small school in a far flung place for being able to provide such a high level of competitive swimming to a great number of our students. Our swim team’s early beginnings was developed before our 25m facility was built and the young team showed great resourcefulness to achieve its goals back in 2014 using various other pools on the island.

Our success comes down to our dedicated staff and a can-do attitude from our students. Some of our most successful swimmers have been swimming fewer than 2 years.

Since then, and the team’s “rebranding” as the Samui Sharks, it has developed into a great team under the watchful eye of Mark Withers, a dedicated teacher and mentor for the past 3 years. This year is no exception and Mr Withers has already planned the whole year’s schedule for his swimmers setting goals for competitions at home and away.

Students have to show their ongoing commitment to earn their place in the squad. Try-outs were held in early September giving every member of the school from year 3 and up the opportunity to join the team. Students are also assessed in their weekly swimming lessons and talent is spotted and developed at this stage. The tryouts allowed Mr Withers to gauge the ability of the swimmers and create the best possible training plan for each swimmer according to their needs.

Training for the Sharks takes place 4 mornings a week at 7am as well as 3 after-school sessions. Training is structured based on the ability and the age of each swimmer. Morning sessions are intense and very physical, whereas extra-curricular sessions are designed to develop technique and stroke improvement in our budding swimmers.

Swimmers are chosen to represent the school once they are ready for competition on a fitness and technical level usually, when they reach year 3 although some younger swimmers may be considered if they are technically able.

Five swimming trips already scheduled,

and we're only just beginning

The Sharks are preparing themselves for the busy schedule of the year, events away and at home. Mr Withers is excited to have secured a team slot in the BISP Flying Fish invitational which sees many international schools from across the region take part.

The team is also hoping to improve on its 3rd place title of 2018 at the TOSL event in Thanypura, Phuket. This event is held over 3 competitions, with final individual and team place rankings, being determined in June 2019.

We recently attended the 1st session with great results across the team: Click here to read the report from Mr Withers.

Spoiler alert: 7 school records were broken in this event, where 29 Sharks competed -- 5 of them competing for the first time.

We are also actively participating in Koh Samui swimming competitions

The team is greatly looking ahead to the challenge of competing against Oonrak school in November and a similar event later in the academic year. Local competitions are excellent training for our developmental squad and the chance for progression swimmers to shine.

Our many in-house school events are always well-received by students and parents alike. We will host our annual events including: the Senior School Tria-ton 2019 -- a challenging event, for seniors only, testing their stamina and skills; the Swimathon 2019 in Primary -- a fundraising event focusing on environmental causes and finally the inter-house Swimming Gala 2019.

Events such as these support our accomplished swimmers’ to achieve their goals but also involves all our other students in their endeavour to try new things.

All this would not be possible without the

hard work of our Swimming coach and the Stingrays' support

Mr Mark Withers, a Swim England (ASA) Level 2 Swimming Teacher, approaches his varied coaching commitments at all levels with professionalism and dedication. Within a day’s teaching he will be taking the early morning swim squad through their paces, followed by a 4 year old beginners’ class focusing on basic water skills and then teaching a mixed-ability year 8 class the challenges of endurance and technique, finally supporting a mixed-ability progression extra-curricular group of students how to achieve their goals in the pool. His day will only be complete once he has squeezed in a couple of hours of private tuition at the end of each day. Such knowledge and dedication have proved the success of the ISS swimming programme seeing it flourish over the years.
