Training for a Half Ironman (aka Ironman 70.3 or Middle Distance Triathlon) should be fun. And it definitely shouldn’t take over your life. Follow these five steps to ensure you enjoy your half iron experience as much as possible.
1. SET YOUR GOAL
First thing first, work out what you want to get out from this experience.
Do you want to smash pbs and qualify for world champs? Or is this more of a game of survival; you want to get around the course with a smile on your face and be able to enjoy some post race beers at the end?
Once you’ve made this decision, it’s time to put together a training plan.
2. MAKE A PLAN
Whether you’re uber scientific about this; or you just mentally sketch out the days and time slots that you’re able to train – the key here is that you set out something that works to your schedule and you are able to find a routine.
As a minimum you should be doing three 1 hour sessions during the week and then use the weekends for the longer sessions. You need to understand that if you are racing for five to seven hours, you should also have trained to go that long; so don’t hold back on the weekend training.
Even with a base level of fitness, you should give yourself at least 6 weeks to train and your training should gradually build up in intensity so as to avoid injury.
3. FIND A TRAINING BUDDY
Friends are the ones who motivate you to leap out of bed in the morning. Especially during the winter months. And a long weekend training session is best shared; particularly when it comes to the cafe stop for coffee and cakes.
If you haven’t signed up to this race with a mate, consider joining a triathlon club – there are plenty around. You’ll have lots of questions along the way, so it’ll be a real help to have people around you who know what they’re talking about.
4. MIX IT UP
Make sure you mix up your training – focusing on both your strengths and weaknesses – but also make it fun by adding variation to your sessions, both in terms of intensity but also locality.
Be it running around a track, through fields, or simply as a commute to work; cycling on a watt bike in the gym, around the park or along county roads; swimming in your local swimming pool, in the sea, or in the lake.
The 70.3 includes some long distances, but in some sessions it will help to work on speed and power rather than just stamina. Sprint cycles and Fartlek runs are particularly useful for working on both your aerobic and anaerobic systems. They also mean you can have a good, quick workout and open up some valuable free time.
Variety is the spice of life and ironman training is one hell of a lot more fun if you keep things interesting for yourself.
5. DON’T FORGET ABOUT NUTRITION
In an Olympic distance race you can get away without paying much attention to nutrition, but try that in a Half Ironman and you could be in trouble.
You should use your training to work out how many calories per hour you should be taking on board; and also to determine what works best with your stomach. Energy gels react badly with some people; and you don’t want to leave it to race day to find out you’re one of them!
On race day, you will need to be consuming slow energy-release carbohydrates such as flapjacks for the long time period, as well as salty foods such as pretzels for the amount you’ll sweat out, so it’s vital to have practiced this beforehand. Keep hydrated with electrolyte drinks or hydration tablets which have carbohydrates and sodium in.

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.

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. 🏅
