Triathlon treats to kickstart your GO TRI journey

When starting out on your triathlon journey it can be difficult (and expensive!) to work out what equipment is essential to take part. We’ve teamed up with Decathlon to create a list of our top triathlon items that you can add to your Christmas list, making sure you’re ready to dip your toes in.

(Jump to: Swim | Bike | Run)


Swimwear will always be required for the swim element of a triathlon, this can be either a one or two-piece set. If you decide that triathlon is the sport for you, you may also choose to purchase a tri-suit which can be worn throughout the swim, bike and run when competing.

If you decide to train or race in open water, it is likely that you will be required to wear a wetsuit. This will help you keep warm and float more easily. When competing, some events may offer wetsuit hire, but if not, there is a wide variety available for you to purchase at different price points.

Additional equipment you will need for the swim includes goggles and a swim cap. Although many events provide event-branded swim caps for visibility, you may wish to purchase one for your training, so you know what to expect on race day.

If you already have a bike at home, whether that’s a road, mountain or hybrid, you can dust this off for your GO TRI. If not, there is a wide range available to purchase and we guarantee that once you’ve got yourself in the saddle, there will be no limit on where you can go on two wheels.

Whether training or taking part in an event or GO TRI activity, a helmet is always mandatory. We recommend that you invest in a helmet which fits your head well and will therefore remain secure whilst on the bike.

You’ll be relieved to know that there is only one piece of equipment required for the run element of a triathlon and that is a comfortable, supportive pair of trainers.

For GO TRI events you will only need one pair of trainers for the cycle and run elements, keeping your transition process simple.
