Will is a full time coach and has been coaching Triathlon for 21 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 200 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 is the Head Coach and Founder of Precision Race Team the current UK and EMEA No. 1 IRONMAN Team.  The team was rebranded in 2018 from ONE Triathlon RDS which was also an award winning team at ITU.  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.

Will coaches across the full spectrum of beginner to elite and enjoys the variety of challenges that comes with that.

Over the last two decades Will has also coached and supplied expert knowledge to brands and publications such as HUUB, Speedo, Gordon Ramsay, The Times, The Telegraph, The Mail on Sunday, ITV’s Good Morning Britain, 220 Triathlon as well as numerous online publications.

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.

Asked last year what it was that kept him in the sport he explained that it was the people and the community both the one created wit PRT but also the wider triathlon family.

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 a family man with two young children and a dog so fully understands the challenges of training and balancing life’s priorities!

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. 😉

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.

Jake has enormous experience in the cycling and more specifically bike fitting world.

The preferred supplier for Specialized UK Jake has worked with numerous athletes to ensure performance, aerodynamics and comfort.

Don’t tell him we said this but we have heard him called a magician…

Jake used a Retul bike fitting technology but importantly is able to apply this to the individual not just letting the computer do the work but endeavours to ensure the fit is fit for purpose, pun intended, be that to the bio mechanics of the individual or the riding needs – racing, triathlon vs critical racing, sportive, leisure riding and so on.

Jake grew up racing bikes, indeed he still does.  However, he always had a passion for the technical side of cycling which motivated him to study and develop his very successful fitting business.


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.
