Thinking about taking on a triathlon? Once you’ve chosen a race and started swimming, cycling and running, you might be wondering what gear you need for training and for race day.

But when you’re just starting out in multisport, figuring out exactly what triathlon kit you need can feel overwhelming. What should you be prioritising for your first race? And what are the added extras you can shop for later on once you’ve well and truly caught the triathlon bug?

In our triathlon kit list for beginners we’ll guide you through the must-haves and the nice-to-haves for training and race day so you can get geared up for your first event.

Essential Beginner's Triathlon Gear & KIt

Triathlon gear for beginners: the essentials for getting started

As you get ready to take on your first triathlon, it’s inevitable that you’ll need to invest in some extra kit. But that doesn’t mean you need to spend a fortune. Take a walk round any triathlon transition and you’ll find plenty of ‘nice to have’ bits of kit that aren’t strictly essential to get you to the finish line.

Here’s our recommendations for the triathlon gear you really need when you’re just getting started.

Swimming

Swim suit or shorts/jammers

For your regular training sessions, as a minimum you’ll want to make sure you’ve got a comfortable swimsuit or a pair of swim jammers to wear to the local pool. Look for chlorine-resistant fabrics to make sure your swimwear can withstand your training.

Goggles

Goggles are another essential for training and on race day. It can take a bit of trial and error to find a pair that fits your face, but a well-fitting pair of goggles should sit comfortably around your eyes and you shouldn’t have to do them up really tightly to avoid leaking. A clear pair is fine for pool swimming, but if you’ll be swimming in open water it’s worth also having a smoke-tinted pair of goggles to act like sunglasses in sunny conditions.

Swimming wetsuit

For a pool-based triathlon, you can either race in your swimming kit or wear a tri suit for the whole event. But for an open water race, unless the water is particularly warm a wetsuit will usually be compulsory. Make sure you choose a triathlon or open water swimming wetsuit, rather than a generic surfing wetsuit.

A triathlon / swimming wetsuit will be specifically designed to offer the flexibility you need around the shoulders to swim comfortably, and you’ll be able to take it off quicker in transition. Wetsuits can chafe around the back of your neck, so it’s also worth adding some wetsuit lube to your kit bag for added comfort.

Cycling

Bike

For your first triathlon, a top of the range, triathlon-specific racing bike isn’t necessary. In fact, you’ll find plenty of beginners taking on their first few triathlons on an entry-level mountain bike or a hybrid/commuting bike. But a road bike is an ideal choice if you enjoy cycling and want to have the perfect balance of speed and comfort.

Puncture repair kit

Whatever bike you choose to tackle your first triathlon on, make sure you also have a basic puncture repair kit with you during both training and racing so you don’t end up stranded. This will usually include tyre levers, at least one spare inner tube and a small hand pump or gas canister to reinflate the tube. It’s best to get a saddle bag (which attaches to your bike underneath the saddle) to carry it all in.

Helmet

Every triathlon event will require participants to wear a cycling helmet during the bike leg. On race morning, you’ll have to put your helmet on when you arrive to set up your transition zone so that the event marshals can make sure your helmet fits and fastens correctly.

For your first triathlon, you don’t necessarily need to spend a fortune on an expensive aero helmet (though if you want to save precious seconds it can make a difference). An entry-level lid will do the trick, just make sure it’s specifically designed for cycling so it offers the correct level of protection and fits comfortably.

Tri suit

While it is entirely feasible to either wear cycling kit or running kit for a triathlon, we’d highly recommend treating yourself to a tri suit. You won’t have to stress about getting changed after the swim (particularly when a lot of local events won’t have a dedicated changing area) and you’ll be more comfortable on the bike and the run.

Running

Running shoes

A comfortable, supportive and well-fitting pair of running shoes really are an essential for triathlon training and racing. Running is high impact, meaning the wrong footwear can quite quickly lead to injuries.

Unless you’re planning to take part in XTERRA or off-road triathlons, a pair of road running shoes will do the trick. Ideally, look for a lightweight running shoe with good ventilation to keep your feet comfortable during warm weather training and racing.

Race belt

Almost every triathlon event will require participants to wear a race number during the bike and the run. For obvious reasons, you can’t really wear a paper number during the swim which means you’ll either have to spend time pinning it on to your tri suit in transition before you head off on the bike. Or, if you’re changing kit between the swim and the bike, lose time carefully trying to put your cycling/running top on without ripping your race number.

This is why you need a race belt – an elasticated belt, usually fastened by a buckle, with attachments for your race number. It’s easy to slip on in transition. Have the number facing the back on the bike, then spin it round so your number is on your front for the run.

Added extras to maximise your triathlon performance

Once you’ve completed for your first triathlon and caught the multisport bug, you might want to start adding some extra bits of kit to your triathlon gear collection to help you improve your performance at your next race. Once you’ve got the essentials covered, here’s our top picks for the ‘nice-to-haves’ that will help you level-up your training and racing.

Cycling shoes

If you’re new to triathlon, but already an experienced cyclist then you may already be using ‘clip in’ cycling shoes on the bike. But if not, getting a pair of cycling-specific shoes and clip-in pedals can really help you to improve your speed on the bike. Unlike riding on flat pedals, riding clipped in means you can make use of the entire pedal stroke – pulling ‘up’ as well as pushing down – which will help you to ride faster.

GPS sports watch

Once you’ve got the basics of swimming, cycling and running down the best way to start improving your performance is by completing specific training sessions. And a GPS running or multisport watch is a great tool to help you tick off those sessions.

During the race, you’ll also be able to check your pace to make sure you’re not setting off too fast, or leaving too much in the tank. Once you start tracking your training, you’ll be able to identify the areas where you’re strongest and weakest so you know precisely what to work on.

Heart rate monitor

Even the shortest distance triathlons are an endurance event, and the key to success is being able to pace yourself from start to finish. Go too hard at the start, and you’ll blow up and lose time as you drag yourself to the finish line. A heart rate monitor is a handy tool to give you an objective measure of your effort. Use it in training and compare how you feel, to the reported heart rate. This will give you an idea of what pace you can hold, and for how long. Pace yourself well during a triathlon, and you’ll find yourself overtaking plenty of people who’ve gone out too fast.

What essential equipment and gear do I need to do a triathlon?

The essential kit you will need for your first triathlon includes: goggles, a bike, helmet, puncture repair kit, running trainers and a race number belt. You might also want to consider a tri suit and a wetsuit for races with open water swims.

Do I need a wetsuit for a triathlon?

For triathlons with open-water swims wetsuits are often mandatory, unless the water is very warm. Choose a triathlon / swimming wetsuit rather than a surfing wetsuit to make sure you can swim comfortably.

What should I wear for a triathlon?

You can wear cycling or running gear for a triathlon. However we’d recommended wearing a tri suit so that you’ll be comfortable during all three disciplines, and you won’t have to worry about getting changed after the swim.

What type of bike can I use for a triathlon?

You can use any type of bike for a triathlon, as long as it is safe to ride – and not an e-bike. A mountain bike or a hybrid bike is fine, though a road bike will be the fastest option for a beginner.

What are triathlon shoes? And do I need them?

Triathlon shoes are specific type of cycling shoe designed to be quick and easy to put on and take off. Triathlon shoes are not essential for beginners. You can cycle in your regular cycling shoes, or use flat pedals and use your running shoes for the entire race if you prefer.


This list of essential triathlon gear for beginners will ensure you’re ready to race and feel confident on the start line. The next stop? A training plan to help you get race ready!
