who we are

At Precision we have a full team of coaches, medics and specialists.  You will have your lead coach but we regularly consult on athletes to make the best use of the team’s experience in coaching which covers the full spectrum of working with novice athletes all the way to Olympic athletes and World Champions.  This sharing of knowledge is really effective to ensure strong results for the athlete.






Will is a full time coach and has been coaching multisport for 20 years now and over this time as both a coach and athlete he has had the good fortune to work with and learn from some legendary coaches. The lessons learnt he has implemented into his coaching guiding over 150 athletes to Great Britain Age Group success with numerous Top 10, podiums and champions across the whole range of ITU World, European, IRONMAN and Challenge Family races along the way.

Will has had further success with the team he created in October 2010, ONE Triathlon RDS which more recently has been re-branded into Precision Race Team. The team is largely made up of top 1-5% Age Group athletes with well over 100 Great Britain Age Group international athletes as well as several World and European medalists.

The truth is every athlete is different and deserves an individual approach. Will offers strong guidance and entirely individualised targets. However, feedback is vital. Coaching is a relationship and as with any relationship communication is key. Will encourages as much feedback and contact as an athlete can give but will also work with the athlete to educate them as to the really important information to feedback on from a performance perspective as well as the information important to them as an individual.

Will has competed in over 200 triathlons and duathlons across all distances ranging from local races to multiple World and European Age Group Championships from sprint to long distance generally placing in the Top 10.

Still competing, his current focus is IRONMAN and IRONMAN 70.3.

Originally a swimmer and runner, Will competed to a National level and then moved over to Triathlon whilst at university. He quickly established himself in the sport and has now been competing to a high level for over 20 years.

Formerly a Captain in the Royal Military Elite Close Protection Unit, Will works to a very high standard with meticulous attention to detail.

He is married with two children and a cat and fully understands the challenges of training and balancing life’s priorities!

I have been a professional athlete or coach since I was 17 years old.  As an athlete.  I raced at the Olympics in Athens and 2 Commonwealth games. I raced for the GB Elite team every year at Triathlon and Duathlon while I was competing finishing top 15 in the World multiple times and reaching the podium at World Cups, the highest level of short course racing before 2010.

After stopping racing due to illness, I then coached Helen Jenkins my wife from 2007 after a season of injury. In 2008 Helen became World Champion for the first time. Since then she has been to 3 Olympics as an athlete and has won another World Title in 2011. When Helen stands on the start line she is one of the most consistent performers in the World over short course racing.

I have coached amateur athletes to IM and 70.3 personal bests and coach a number younger athletes aiming to help them achieve their potential.

I have been fortunate to spend time around the best and most respected athletes and coaches in the World helping me understand there are many ways to achieve your best and lots of tools and methods you can use to do this.

It is vital to have a plan to give yourself the best chance of a successful outcome on a given day. The aim of the plan is to stick to it as best you can, but as with other things in life, plans go wrong and its important to then be adaptable and responsive when variables and uncontrollables present themselves.  The ability to adapt and focus on the goal is key to success.

As a younger athlete I competed in Surf Lifesaving where I represented GB and won a Silver medal in the World Championships. I fully committed to triathlon when I was 17 and made a career for myself as a professional athlete and then as a coach supporting Helen. I enjoy working towards goals and do this through coaching since retiring as an athlete. I still train in all three triathlon disciplines and enjoy pushing myself. More often than not running is with the baby jogger and the baby with some great 80’s music for us both to enjoy.


I am proud to have represented my country 3 times at the Olympics (Beijing 2008, London 2012, Rio 2016) and become ITU Elite World Champion twice. I have been an elite athlete for over 15 years and spent time with coaches and athletes from all over the world. Triathlon has given my family and myself a great life and I’ve made lots of friends and great people along the way.

Having a plan is key for me as an athlete. I have had a lot of injuries during my career and have learnt a lot about injury management and how to get the best out of myself on less training volume than I would have liked. I am hugely motivated by improving in all three discipline and I love having a plan to focus on and map out the path to improving. It’s been important for me to follow a  good gym program due to injuries and mechanical issues I have had throughout my career . This has been a key to my success. I know that with a great short-term training program that is specific and detailed I can be the best in the World if I am able to get through it.

I feel so lucky that Triathlon and sport have given me great opportunities to travel and see the World I couldn’t have imagined when I was younger. I love training and sport and even when I stop competing I hope to carry on swimming, biking and running and be able to show my daughter what I did for a career. Marc and I love being in the sea as much as possible and if we aren’t training then we would be at the beach. When we take holidays now we still exercise every day because we love what we do. We love live music, nice hotels great restaurants and cheap restaurants, actually, we just love food, a bonus that comes with doing lots of training.


Marc has an extensive background in multisport coaching, yet his true expertise is within performance gains in cycling.  Having worked alongside a World Pro tour team, military cycling/triathlon teams and run numerous overseas training camps.  Marc brings an array of experience over and above the physiological requirements to enhance performance. Marc has been fortunate to work with some excellent athletes; from novices completing their first sportive/triathlon to assisting triathletes qualify and race at the Ironman World Champions, 70.3 World Championships, several ITU/ETU championships and cycling national time trials and road races.  Achieving several World & European medals.

Marc is also a British Triathlon Age Group Team Manager.

Marc’s coaching philosophy is to impart his knowledge, experience and passion in order to assist athletes to improve and achieve their goals and objectives.  Marc believes that all athletes are different, with different needs and goals; therefore each athlete will have different training and coaching requirements.  Marc’s passion and drive is unsurpassed and thrives on passing on his knowledge and seeing the results that can be achieved by working closely together.  Inculcating an optimal relationship of trust.

Marc has competed across a plethora of multisport disciplines for over 20 years, from racing at an early age of 14 to being fortunate to race full time for 2-years in Spain in his younger days.  Most recently Marc has represented GB Age Gp in the ITU/ETU championships across several disciplines and completed 6 x Ironman events and in 2018 qualified for the World 70.3 Championships. Marc’s passion is cycling where he has an outstanding understanding of power training and how to optimize time to deliver the results.

Cassie is a full time coach and speaker.  As an Olympic medalist & international swimmer over 200, 400, 800 1500 & 10k across 3 disciplines, Cassie is uniquely qualified to help any level of swimmer. An ASA level 2 coach, Cassie coaches junior competitive swimmers, masters and Triathletes across the full spectrum of ability as well as Open Water swimmers who want to focus on their technique.

Cassie has had some outstanding results since starting full time coaching in 2011.

Cassie draws on her vast experience of coaching and competing across all levels.  Evidence based training is very important to her keeping up to date with the latest developments in swim coaching she is able to cut through attempts to reinvent the wheel and focus on what really works.

She is flexible and personable which is extremely important as no one athlete is the same.  She utilises her experience to adapt her coaching to ensure results with whomever she is working with.

One area that Cassie is particularly strong at (unsurprisingly) is helping athletes get comfortable in Open Water.  This is something that many athletes struggle with be they confident swimmers or not.

Where to start?  Probably with her Olympic Bronze Medal in the 10,000m Open Water Swim.  Backed up nicely with two World Championship Silvers, a World and European Cup win.  Cassie also made history as the first swimmer in the world to both final in the pool and medal in the open water events at an Olympics.  She represented Great Britain at an elite level for over 10 years. Cassie is simply one of the best swimmers that Great Britain has ever produced.

Her passion for swimming is unsurpassed and in particular swimming outdoors.  The only thing she is more passionate about is her lovely dog Daisy and maybe her partner Martin. 😉


Alice is a UKSCA Accredited Strength & Conditioning Coach with a sustained record of achievement in providing support to elite, youth & developing athletes including Olympic & Paralympic Swimmers for the past 8 years.

After graduating with a first-class degree in Sports Science, Alice pursued a career in Strength & Conditioning achieving her UKSCA accreditation in 2012. She was responsible for the training of both an Olympic Swimmer & Paralympic Swimming double bronze and silver medallist for the London 2012 Games and since then has coached numerous swimmers to podium success at the European and World Junior championships, Youth Commonwealth Games and multiple National Championships.

Alice has also worked with organisations such as Portsmouth Football Club, British Swimming, Swim Ireland, Surrey Country Cricket Club, GBR Ice Hockey and McLaren to name but a few. As a triathlete herself, Alice has helped a wide range of athletes develop and implement a comprehensive conditioning programme into their endurance training plans with an emphasis on injury prevention and maximising performance.

Alice’s main question for any athlete is “are you moving correctly?” Her emphasis on correct technique ensures that all training programmes are bespoke to each individual athletes’ needs as well as the requirements of each specific sport. Alice’s training programmes focus heavily on using exercises that will ensure that you are as efficient as possible to maximise your race day performance and when correctly implemented into your training schedule, Strength & Conditioning can be the training element that gives you the extra edge come race day.

Alice had always had a background in competitive sport having been a dancer and swimmer growing up and is now a member of the Triathlon team Artemis Tri. Alice started competing in Sprint Triathlons in 2014 where she qualified for her first AG World Champs in her second ever triathlon. Since then Alice has represented GBR in the 2014, 2015, 2017 & will be competing in the 2018 World Championships in both Sprint and Standard Distances and also the 2015, 2016, 2017 and 2018 European Championships. She also tried her hand at Elite racing in 2016 which is something she is looking to go back to in 2019 as well as being bullied by Will to step up to the 70.3 distance. 😉


Will has been working in sport for over 10 yearsand experienced working with athletes to the highest level competing on the world stage. He has worked within both team and individual settings, aiding in health and performance at the Commonwealth Games, Tour of Britain, Tour de Yorkshire, Tour of Poland, Prudential Ride Classic, Ironman Kona, Track Worlds and World heavyweight boxing, with such teams as ONE Pro Cycling, TREK Drops and Team GB Invictus Games.

Having a masters degree in sports nutrition Will still works academically to further our understanding of nutrition by currently performing research at Middlesex University in endurance and ultra-endurance sport.

The method Will utilises is the combination of evidence-based practice that is applied to the individual, lifestyle, goal and sport to make an approach that is both founded in science but also realistic for each athlete making it as bespoke as possible.

Will understands what it’s like to be an athlete and has closely worked on the road with professional athletes all over the world but also what it’s like to work 9-5 and still have to fit in all your training and life around it and his approach very much relates to this being able to tailor it to your lifestyle and make the diet that’s right for you.

Originally Will competed in Powerlifting and Strongman but since November 2017 has switched to purely cycling as he trains to achieve his world record attempt of riding the length of Europe in the fastest time by bike in April 2019. He believes in experiencing the sport of the people he works with and has taken on this challenge not only to do that but to show no matter what body shape, age, gender you can achieve your goals.
