33 essential items to pack for a triathlon

Packing these 33 items for a triathlon will ensure a smoother event day so you can focus on giving it your all and coming out with a personal best.

All the training is done and it’s almost event day, but keeping check of all the bits of equipment you need for a triathlon is difficult. Writing a list of all the items and splitting them into the different disciplines of a triathlon is an easy way to keep track and be prepared for event day. The following list of 33 essential items will help you pack for your next triathlon.

Find your next triathlon event

Swim

1. Wetsuit — check whether your triathlon requires you to wear a wetsuit, is wetsuit optional, or requires no wetsuit to make sure you’re meeting any race demands. On top of that, your wetsuit needs to properly fit you, and be comfortable so check out the different options before you buy

2. Goggles — try on a few types to find what works for you as dealing with leaky goggles throughout your swim will really throw you off. Once you have your perfect pair, it’s a good idea to buy a second pair in a different tint so that you have something for all conditions

3. Tri shorts, swimsuit or tri suit — A basic pair of tri shorts with a little bit of padding will make your bike leg much more enjoyable, but if you’re doing multiple triathlons or decide this sport is for you, it might be worth investing in a tri suit

4. Swim cap — this can either be used for the actual event or just for your warm up swims

5. Lube/Vaseline — this helps to stop any chafing

6. A towel — for the transition between swim and bike

7. Bike — If you’re new to triathlons any bike will do but if the tri bug hits you, then you can start thinking about getting a more appropriate bike. Try and get it checked out at your local shop before an event to make sure everything is running smoothly.

8. Helmet — this is obligatory for all triathlon events. Make sure it fits properly and the strap is on tight

9. Sunglasses— these will help prevent any glare from the sun, but will also protect your eyes from any insects or dirt flying around

10. Cycling shoes — if you’re new to the triathlon scene, mountain bike clips are a good starting point for cycling shoes, as they clip in and out more easily

11. Socks — there’s a lot of debate about whether to wear socks on the bike as it takes up a lot of transition time. This is completely down to your personal preference

12. Tool kit — floor pump, spare inner tubes, multi-tool, CO2 (make sure you practise with this beforehand if you’re planning on using these during the event)

13. Technical equipment — for example, if you want to wear a technical watch, heart rate monitor, GPS, bike watch/computer

14. Bottle(s) — pre-filled with your choice of drink, make sure that the water or electrolyte is fresh that day.

15. Number belt — in case you’re not using safety pins. If you aren’t using a number belt you should have your race number pinned to your tritop, ready to put on in the swim to bike transition

16. Jacket — this is totally dependent on the weather and the time of year that your event is happening

17. Energy gels — this can also include any bars or other nutrition that you want for during the actual event. Normally people choose to have some during the bike discipline and in the bike to run transition.

18. Running shoes — taketwopairs if you have a late start time. One to leave in transition and one to warm up in. Just make sure they’re comfortable and well worn in

19. Hat/visor — useful for keeping your hair out of your face, and preventing against sunstroke if you're running in the heat

20. Socks — again this is where some people choose to wear socks and others don’t, but if you know you blister you could also carry plasters to put on in the transition

21. Plasters — this is in case you’re running sockless or for using after the event

Additional Items

22. Event registration paperwork and ID

23. Any pre-event drinks or snacks

24. Warm clothes for pre- and post-event

25. Comfortable footwear — to change into after the event

26. Safety pins — this is for your event number if you are not wearing a number belt

27. Roll of duct tape — this is always useful to have on hand

28. Post-event food

29. Money — try and take cash as there may not be a cash machine nearby

30. Bin liner — to help keep things dry

31. Toilet roll

32. Waterproof sunscreen

33. Any medication — for example, asthma inhalers

The Challenges Women Face in Running and How It Impacts Participation

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Before we kick things off however, we should highlight that female participation in running events is growing, and this is a great thing! According to data from Let’s Do This, women in their 20s are the fastest-growing demographic in event participation this year. However despite this, women are still 16% less likely to run every week compared to men. This disparity is particularly striking given that women report higher levels of personal benefits from running, such as improved fitness, better sleep, and reduced stress.

The reasons for this are complex and personal, however we have broken down three key challenges discussed during our panel and the solutions explored that could help address them.

1. The Pressure of Pace

One of the biggest hurdles for many women is the pressure to run faster. Despite the average UK woman’s running speed of 06:37 min/km (according to Strava), most run clubs don’t cater to this with the slowest pace often around 6 minutes per km. Add to this the relentless focus on personal bests and fast times on social media, and it’s no surprise that many women feel too intimidated to join in. 

Thankfully, there are starting to be more people rebelling against this speed obsession, including our panelist, Emily Shane. Emily has been leading the charge to encourage more women to disregard pace and focus on the experience of running to drive uptake amongst women. Initiatives like events without cutoff times and more inclusive pace groups at running clubs are vital to creating a more welcoming environment and broadening the benefits of running to the experience and community. 

2. Perception of Sport in Schools

One of the topics hotly discussed was how for many girls, the barriers to enjoying physical activity start at school. Puberty, coupled with changing bodies and fluctuating emotions, can make sports feel daunting and uncomfortable for teenage girls. Research highlights this disparity: only 38% of girls enjoy sport and exercise compared to 53% of boys, and just 26% of girls feel confident in physical activity versus 43% of boys.

The panel emphasised the need to address this such as:

  • Introducing a wider variety of sports and fitness activities to cater to different interests
  • Providing more supportive and confidence-boosting PE kits.
  • Showcasing more female role models in sport to inspire young girls.

By addressing these issues at the school level, we can foster a love of sport that lasts into adulthood.

3. Treatment at Events

This is a topic that panelist Sophie Power, founder of SheRACES is incredibly knowledgeable and passionate about. Even at organised running events, women often experience unequal treatment. From “unisex: t-shirts (which are actually designed for men) to a lack of sanitary products in portaloos, these "small things" can collectively make women feel like an afterthought. Prize money inequality and rigid event policies—like no deferral options for pregnant or postpartum women—further highlight these disparities.

Thankfully, initiatives like the 50:50 campaign by Threshold (a campaign to get 50% of women at Ultra startlines vs. the current average of 30%) and the advocacy work of SheRACES are driving change, and there are many amazing event organisers such as Maverick, Threshold, Why We Run and many more, that are working hard to make their events are inclusive as possible for women. 

Despite these challenges, the panel and attendees felt overwhelmingly optimistic about the future of running for women and the benefits it brings us. Progress is being made, however we all need to add our voices to the conversation to help more women get into the sport and reap the benefits. 

Some Helpful Resources

Here are a few helpful resources. This list isn’t exhaustive by any means, however is a good starting point for those looking for inspiration on where to start.

From Radio to Race Day: Hattie Pearson’s Path to Endurance Event Glory

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Just say YES

Hattie’s ‘yes’ streak started when a friend and her decided to do a sprint triathlon together. “We had such a great time,” Hattie recalls, “and I was like, I want to do more of this.” That spark quickly turned into a blaze of ambition. By the following year, she was competing in Outlaw triathlons and even signing up for a full-distance Ironman—before completing her first half-distance event. “I didn’t give myself the choice to not carry on,” she says.

The Power of Community

For Hattie, discovering the 10IronWomen network—a group committed to gender parity in triathlons—was a game-changer. “It’s amazing to see a community encouraging women and non-binary folk to show up,” she explains. “Seeing others doing it made me think, I want to be a part of this.” That sense of solidarity and shared purpose has been a recurring theme, whether she’s lacing up for a winter triathlon in the Alps or a grueling ultra-marathon closer to home.

A Year of Big Goals

This year, Hattie set herself a dizzying list of challenges. She swam 500 kilometers (yep, that’s half a million meters!) and tackled a range of events, including a winter triathlon complete with ski touring, the Étape du Tour cycling challenge, and her first ultra-marathon. Each was hard in its own way—whether it was battling snowy trails with crampons or smashing out seven-and-a-half-minute miles for 13.1 miles. But for Hattie, the difficulty is the point. “Every time I achieve something I thought was impossible, I remind myself: I can do hard things.

Balance and Burnout

With goals that ambitious, fitting it all in can be a challenge. Early mornings help. “I’m one of those people who can get up at 5:00 a.m,” Hattie admits, however it also takes a lot of discipline. With her work on Hits Radio starting later in the day, she carves out time for training, dog walks, and the occasional tantrum over broken goggles. “I’ve definitely had those ‘forgetting-my-swimming-costume’ moments,” she laughs. But her key to staying motivated is simple: keep it fresh and fun. Whether it’s joining her triathlon club for training or trying a completely new event, keeping it fun and different is the secret to staying motivated and on track to reach your goals. 

Advice for Aspiring Endurance Athletes

For anyone looking to follow in her footsteps (or strokes), Hattie has this advice:

  • Be patient. Results don’t come overnight, and the journey is as important as the destination.
  • Stop comparing. “Your journey is completely your own. Social media only shows the highlights,” she reminds us.
  • Find your community. Whether it’s a running club, a neighbor for early morning jogs, or an online network, accountability and camaraderie make all the difference.

What’s Next for Hattie?

In 2025, Hattie plans to tackle her first multi-day event, the Monster Triathlon. Admittedly it is as scary as it sounds, kicking off with a 5K swim in Loch Ness, followed by a 1,000-kilometer bike ride to Windsor, and wraps up with a casual 50K run to London(!). Her goals also include more open-water swimming, trail running, and maybe—just maybe—an even bigger endurance challenge. (Though definitely not swimming the English Channel: “No way am I swimming through jellyfish without a wetsuit!”)

Hattie Pearson’s journey is more than a personal triumph. It’s a testament to the power of showing up, saying yes, and proving that with the right mindset, anything is possible. Whether you’re tackling your first 5K or dreaming of an ultra-marathon, Hattie’s story is proof that the finish line is worth the hard miles. And when you cross it? You’ve won your race—medal or not. 🏅
