Signing up to a triathlon is no small feat. Training for it will be a huge commitment, both on your time and body, so it’s definitely a good idea to put some thought into your kit. As you’ll be doing three different forms of exercise during your triathlon, you’ll need to invest in the correct gear for each one:
Swimming gear: A good quality swimsuit or swimming trunks, some goggles with a good seal and a swimming hat (especially if you have long hair) are key. If you’re completing the swimming stage of your triathlon outdoors, you may need a wetsuit (especially if it’s in the UK!). Buying a wetsuit can seem complicated, so check out SportPursuit's guide to choosing a triathlon wetsuit before you take the plunge.
Cycling gear: A bike that’s in good condition and the right size (go into any bike shop and they will be able to advise on whether your current bike is appropriate) is the first thing to consider. Carefully look at the route and terrain of your triathlon event – this will heavily influence whether you need a road or a mountain bike.

During training, you might be spending the longest hours on your bike, so it's worth having comfortable, well-fitting cycling kit such as padded bib shorts and a breathable jersey as you increase your mileage. For the race, you can use the same padded cycling shorts, or, alternatively, pick out a good tri suit. These are all-in-one items made from quick-drying fabrics which can be worn for all three stages of a triathlon.

Running gear: A good pair of running shoes will do wonders for your comfort and overall performance. It’s also practical to wear proper running clothes (or a tri suit as mentioned above) that are moisture-wicking and supportive. Running socks are also vital. They’ll provide comfort, wick away moisture (aka sweat) and prevent – as much as they possibly can – those dreaded blisters.
