Hi! I'm Sid.

British but global traveller (nomad). From the UK, to Sydney, (Australia), to San Francisco (USA) and Christchurch (New Zealand), where I chased summer for a few years between the Hemispheres, Christchurch and then Girona, Spain. But finding a base now in Boulder, Colorado (USA). Athlete, ex-British Army Officer, Engineer, Consultant, Coach, Commentator, Writer, youngest daughter (of 4), sister, and best Aunty!

More About Me

Born in Nottinghamshire, I spent my school years in Yorkshire (Brownlee country I think it’s now been named). I’m the youngest daughter of four, to my Dad, Bob (a Mining Engineer) and my Mum, Gill (a Math Teacher). I have three older sisters, Anna, Naomi and Charlotte and have three awesome nieces and nephew, Maisie, Jack, Molly and Florence (Flossy).

Sport has always been part of my life. At school I was involved in Athletics, Netball, Hockey and Swimming (although my butterfly stroke got our school relay team disqualified twice, and I still have no idea why). Towards the end of school and into University my focus narrowed to Netball and Athletics (400mH) being lucky enough to represent England Schools at junior level in Athletics (300mH) and England in Netball.

With a degree in Mechanical Engineering (any surprise with my parent’s professions and two of my older sisters also being Engineers), and a Gap Year as an Officer in the British Army (REME), I worked for Shell in the UK, before moving to Sydney, Australia (2007) for a two year assignment. At the end of the two years instead of returning to the UK, I decided I wasn’t quite done with Australia yet. I worked another few years in Australia, in a Management Consultancy, and then a large construction company, looking at business process improvement and project management.

I started Triathlon, a year after moving to Australia. I’d signed up for the Sydney to Wollongong ride (90km), with some work colleagues, and bought a hybrid road/mountain bike the week prior. I loved it and a colleague suggested I try Triathlon. To be honest, I didn’t really know much about the sport, but I found a beginner’s course run by Bondifit and well, the rest is history! Having raced as an Age Grouper for the past few years, progressing from complete rookie to a four time World Champion (amateur) I took the leap at the end of 2013 to step up into the Pro ranks and race against the big kids

In 2014 I relocated to San Francisco, to try to live the dream and chase the Pro Triathlete life. After a couple of years in the USA, I missed the Southern Hemisphere too much and so moved back but this time to New Zealand. I then spent several years chasing summer splitting my time between the Christchurch, (New Zealand) and then the Northern Hemisphere summer in Girona, Spain. When the pandemic hit, I found myself back in the UK briefly (well six months), and then made it back to Girona, where I stayed more permanently for a couple of years. Now, I’m more based in Boulder, Colorado (back in the USAD) having moved here at the start of 2023 to be with my coach Julie Dibens and the JDCrew.

In 2017/2018 I was the fifth fastest British woman of all time over the iron distance. I’m now a four time Ironman Champion, which includes winning Ironman Australia for three consecutive years (2017, 2018, 2019), Ironman New Zealand (2018), and I’m also the ETU European Long Distance Champion (2018), and Patagonman Champion (2023)

In 2022, I finished in the top ten twice at the Ironman World Championships – 7th at the postponed (2020/2021) Ironman World Champs, St. George and then 10th at the Ironman World Championships 2022, Kona. I never would have dreamed a top ten in the World, let alone, two in the same year!

In May 2023 I was hit by a car, during the bike leg of Ironman Brazil, suffering a brain bleed. I was fortunately given a Wild Card for the Ironman World Champions, and managed to build back my recovery and fitness to finish in 16th, in my fastest ever Kona time.

I’m a self-confessed sports junky. Watching, participating, supporting, coaching, whatever it is, I love it. It’s what I thrive on, it’s what I’m passionate about and it’s what gives me a buzz in life. Don’t Die Wondering is what I live by.

Outside of sport, I was voted on (by my peers) to the Athlete Board of the Professional Triathlete Organisation (PTO) and also sit on the PTO Anti-Doping committee. In 2022 I was selected to be part of the Women’s Sport Trust UNLOCKED programme, and I’m excited about the continuing work and power together of this group of incredible women. I’m a commentator, speaker, writer, podcaster; coach; mentor; have my own range of t.shirts; am regularly asked to comment, quote by sports media; and in 2020 launched Sid Squads to help young up and coming female triathletes.

Giving Back

Sport has given me so many amazing opportunities throughout my life, and I’ve learnt so many skills and lessons from playing and competing in sport. Below are some of the organisations I am very proud to be associated with and hope I can inspire and encourage others to get involved.

WOMEN'S SPORT TRUST

The WST aims to promote and encourage greater engagement with women in sport through participation, media coverage, research, and to drive an industry with strong allyship that actively demonstrates that it values women and girls; where strong, diverse female role models are highly visible, and where systems enable diverse talent to get access, opportunity, development and profile. I was one of the original supporters of the WST, and Athlete Ambassadors in it's early days, and in 2022 was part of the UNLOCKED programme. UNLOCKED is about bridging the gap, giving athletes the influence, community and connections to turn intention into action. "It's not about training athletes, it's about supercharging them" - Tammy Parlour CEO

CAF

The power of sport. Giving physically challenged athletes the ability to live active lifestyles like the rest of us, as well as to help reach out to those who are physically challenged to see that through sport, any level of sport it their self-esteem can improve as well as sport encourages independence and enhances quality of life. I’ve been fortunate to meet some incredible athletes through CAF, and I’m grateful for every opportunity I get to work with these athletes.

PTO

Proud to be a member of the Professional Triathletes Organisation, to give a unified collective voice for the Pro Triathletes, as we look to develop and create a better sport for everyone. This is something I'm passionate about, to make triathlon a better sport, more professional, more accessible, more visible, but also to be an organisation for ALL Professionals, supporting the whole membership. I also currently sit on the PTO Anti-Doping board to develop our own anti-doping stance and policies.

BRITISH TRIATHLON SUSTAINABILITY COMMISSION

Exciting to be part of the British Triathlon Sustainability Commission to develop the Sustainability Policy and plan for the sport in the UK and lead the way for other sporting organisations to be more proactive in this area. As well of course to learn from other Governing bodies and sectors as to what we can do, to be more active across all areas of the UN 17 Sustainable Development Goals. Inspiring to sit with a committee full of experts and expertise in this area.
