What goggles should I buy kit for a cross triathlon

These are very much personal preference. It is best to go to a shop, try some on and pick the ones that feel comfortable and are best fitted to your face shape. You may want to get a couple of pairs so if you have any problems on race day and snap a goggle strap for example, you have a back up.

But for the purpose of this article, at such a good price we’ve picked the Aquasphere Kameleon goggles. They provide a good field of vision, perfect for open water swimming and come in a variety of lens types.

Wetsuit – £79.99

kit for a cross triathlon

Most races in the UK require you to wear a wetsuit. You are looking for a swimming wetsuit made of Yamamoto neoprene with no sections thicker than 5mm. Surf wetsuits are allowed, but whilst this will keep you warm, it will more than likely slow you down!

The cheapest we can find is decathlons Aptonia wetsuit. It has 4mm neoprene around the pelvis and legs to support your body position in the water, and 2mm neoprene around the arms to provide more flexibility. On the surface we can’t fault it so at £79.99 it is a bargain!

Men’s available from Decathlon

Women’s available from Decathlon

You can also look at hiring a wetsuit. This is generally around £30-40 for 2 weeks hire and most companies will offer the option to purchase when your rental time is up.

Trisuit (optional)- £29.99

We’ve marked this as optional as you can swim in a costume and put on some shorts and a t-shirt in transition. However you will be far more comfortable in a trisuit. And at £29.99, Decathlons Aptonia trisuit is probably worth saving some chaffing from your swimwear once on the bike!

Bike kit for a Cross Triathlon

Mountain Bike – £499

kit for a cross triathlon


When choosing a bike you want to invest your money on the frame and the fork as these are the things that last.

We would recommend the following

  • Aluminum frame- This is a good middle ground. Carbon is expensive and steel is heavy.
  • Front suspension- air fork, this keeps the bike light
  • Hydraulic brakes- cable brakes are always cheaper but they are not reliable
  • Tyres- These are really important as they provide the grip for riding on muddy or rocky terrain. Budgeting for a good set of tyres will make a huge difference to your riding experience.

It can be done for under £500 – The Vitus Nucleus 275 VR MTB has won MBR’s under £500 hardtail award for 3 years in a row. However, whilst this might be cheap, the best thing to do would be to visit your local bike shop. They will be able to help choose which bike to use and most importantly make sure it fits. Something that you just can’t get from the internet!

Running shoes are like swimming goggles. You need to try some on and pick the ones that are best for you.

You need a sole with a bit of tread to help with grip on muddy/loose terrain, but not something so heavy that it will slow you down. Generally, you can’t go wrong with a pair of Salomon running shoes. We’ve picked the sense escape 2.
