Triathlon Relays Championship

Originally started in 1991, this weekend has become legendary, as much as others have tried to replicate it, the Triathlon Relays is still very unique. In 2015 over 1600 athletes and 100 different clubs joined in the fun that we call 'organised chaos'.

A triathlon is one of the trickiest and most difficult types of event you can try, but the challenge is what makes it great. It comprises of a swimming section, followed by a large bicycle ride, and finally a long stretch of running.

For anyone who has ever done an event involving one sport, such as a 10K run, and found themselves bored by the end, a triathlon might be the exciting fitness challenge you’ve been looking for! Combining three sports – swimming, cycling and running, a triathlon provides a varied and challenging workout that test your fitness and endurance across multiple disciplines.

What is a triathlon made up of?

The distance of a triathlon can vary, but the race will always begin with a swim start. Depending on the length of the course this could be in a swimming pool or an open water swim such as a lake or sea. 

The swimming section of the triathlon is then followed by a cycling section – beginners don’t need to splash out on an expensive new bike, if you already own a mountain bike you can use that for your first few races! The cycling section is considered by many triathletes to be the most challenging part of the endurance event, with standard triathlon courses incorporating a 40km bike leg.

The final leg of the triathlon is a run. Again, the distance will vary depending on the length of the course, but a 10k run is considered standard for a triathlon. 

Between stages there is also a transition, which is often referred to as the fourth discipline. The transition area is where you change your kit between stages, for example switching from your cycling gear to your running shoes. The time it takes you to do this is counted as part of your total triathlon time, so serious triathletes will have got their transitions down to a fine art.

What are the benefits of taking part in a triathlon?

Triathlons are great for those who are looking to improve their fitness, lose weight but don’t like the idea of doing a regular marathon of running event. The varied stages keep training and competing challenging and interesting, providing a total body workout. Those prone to running injuries may also benefit from the swimming and cycling sections, as the movements are lower impact on joints.

Regardless of sprint length, triathlons are typically divided into age groups. This means that you will be competing alongside other triathletes who fall into the same band for age and sex as you, with the exception of triathletes who fall into the separate elite category.

The 'organised chaos' will continue as previous years, only with a new name 'Triathlon Relays'. Our main focus is still that groups of four people join together to complete a triathlon, with everyone doing a swim, a bike and a run. Now you get a few different options.

As requested, we have changed the format of the weekend, adding in the new 'elite style' tag triathlon and there will also be a return of the team time trial on the Sunday.


The move away from the title 'Club Relays' is simple, we spotted that less than 40% of athletes in our regular individual events were members of clubs... we wanted the weekend to be enjoyed by those athletes that were not members of clubs, but ultimately had three friends and wanted to join in the fun. We have also been working alongside British Triathlon Federation & Triathlon England to simply the rules - they are now very simple.

The Saturday, will continue as previous years, with the standard relay format. Each member of the team individually swimming 500metres, before tagging their team mate, and so on, and so on, until all four people have completed the swim. Moving onto the 15km bike, each athlete individually completes the 15km bike, until the last team member then tags the first team member to start the 5km run section.

In the morning, the men's and women's categories will be racing in various categories for National Championship Awards - junior, senior, vet 40 & vet 50. In the afternoon, the mixed category will give the chance for the men's and women's teams to combine and race for more National Championship Awards.

The whole of the re-vamp will be based on the Sunday events. As requested by many of the clubs, we will be hosting the first elite style triathlon relay which is open to all groups. Each team member will swim 300 metres, bike 5km, run 1.5km before then tagging the next team member & they do the same course, until all four team members have completed the course. To add to the excitement, we will also be hosting all of the transition in front of the grandstand area, along with music DJ's and the crazy commentators, this will be mega exciting racing, whether competing or spectating.


There will be three categories racing for National Championships Awards - men's women's and mixed (2 men & 2 women).

The top 10 finishers in each category will then go forward to the ultimate team test - triathlon team trial! All four athletes must race together with the time being taken from the fourth athlete crossing the line.
