TFNTG is a Ninja obstacle training facility for ALL abilities. Whatever your current level of skill, strength, fitness or confidence, training at TFNTG starts with the desire to take on a journey of challenge, progression and hard work, alongside like-minded people.
Our goal is to help every participant become a stronger, fitter and more skilful version of themselves, developing a “Never Give Up” attitude, learning to Adapt & Overcome, and supporting one another along the way. This is the mindset of the modern-day Ninja athlete. This is ‘Sasuke Spirit’.
Sessions at TFNTG are delivered on a pre-booked basis, from one-off sessions to structured courses, alongside a limited programme of adult training sessions.
All sessions are designed to be engaging, challenging and rewarding, giving participants the opportunity to begin their Ninja Training journey under the guidance of our Head Coach & International Ninja Warrior Athlete, Dion Trigg.
Dion and his team of coaches, all of whom are selected for their passion, patience and dedication, provide instruction and support to help develop the essential skills required to overcome obstacles both in training and in life.
This video has been created to inspire children and to show parents what can be achieved through structured Ninja Training with our coaching team here at TFNTG.
I am extremely passionate about working with every child who begins their Ninja Training journey with us, and I am always proud of every success and every challenge they experience along the way, as both are an important part of their development.

Children’s Ninja Training (Ages 5–17)
Our courses are delivered in term-based blocks, aligned with the Wiltshire school calendar.
Each session is 1 hour in duration and is structured and supervised by Head Coach Dion Trigg, alongside Emily Mortin and assistant coach Luke, ensuring a consistent and supportive training environment.
Children are dropped off at the start of their session and collected at the end. At the conclusion of each term, we invite parents to attend and watch a session, giving you the opportunity to see the progress your child has made and the skills they have been developing on the obstacles throughout the course.

We love welcoming groups of children to TFNTG for our structured Ninja Training sessions, providing an engaging and inspiring obstacle training experience for the birthday child and their friends.
Each session is delivered by our coaching team and focuses on developing key movement skills including swinging, climbing, jumping and balancing, alongside coordination, timing and confidence. From the very start, we work to build a positive team environment where every child is encouraged to take part, challenge themselves and support one another.
Children are guided through a range of obstacles, learning safe techniques and progressing through challenges such as scaling our Warped Wall. Every participant is supported throughout the session, with a focus on effort, resilience and personal achievement. Sessions are delivered in the same format as our regular Young Ninja Warriors training programme.
Head Coach Dion Trigg and the team bring their experience as athletes, coaches and parents to create a supportive and rewarding environment. Our sessions are designed to help children build confidence, develop skills and enjoy the process of improving through structured training
Sessions are 90 minutes in duration and are priced at £240 for up to 10 children. Additional spaces are available at £24 per participant. Each booking is delivered as a private, pre-booked group session.
Parents of the birthday child are welcome to stay and observe the session, and guest parents are invited to return towards the end to see the children’s progress and achievements.
Please note: the facility does not provide catering or dedicated party rooms, and sessions are focused on structured activity.
We look forward to welcoming your group to TFNTG, our specialist training facility.

Since opening, we have welcomed athletes from around the world to come and train with our team. Athletes have traveled from across the UK, France, Germany, The Netherlands, Israel, Russia, USA, and Japan.
Here's a reel from Timothy Sheiff's time training here:
Dion Trigg and the team at TFNTG are carefully selected for their passion, patience and dedication, and are committed to supporting every participant in developing the skills needed to overcome obstacles in training and in life.
TFNTG’s Head Coach and International Ninja Athlete, Dion Trigg, founded the facility to deliver structured Ninja obstacle training in Swindon, UK.
"My vision for TFNTG, and for every session we deliver, is to help build confidence, self-belief, determination, patience and self-control in all participants — both children and adults. We focus on developing a Never Give Up mindset with the ability to Adapt and Overcome.
My passion for Ninja Warrior has taken me to compete in 7 different countries, and is matched by my passion for helping others progress through training. Having experienced challenges growing up, I understand the importance of building confidence and resilience, and I aim to support every individual in developing the skills needed to overcome obstacles both in training and in life."
Emily Mortin has been training at TFNTG for 8 years and was a Grand Finalist in Ninja Warrior UK Series 6, Race For Glory.
"What I enjoy most about Ninja Warrior training and coaching is seeing people progress, no matter their starting point. Everyone is on their own journey, and every achievement — big or small — matters.
I enjoy helping people develop new techniques, build confidence, overcome challenges and take pride in what they achieve through their training."
To all those who helped us get where we are today, and continue to do so, we are truly thankful.
