33 parkruns, 4 marathons, peach loops, animal rescue, life time ban from foot modelling, unconventional family holiday, all in a casual Friday morning jog.

I thought about this finish line, possibly every day for the last 8ish months, when I decided I wanted to take the 100 mile leap. For a rare moment in time, I never once thought I wouldn’t do it. I became obsessed with 161, but not in the usual ways. I became obsessed over the total enjoyment of the outdoors, the freedom on the trails being able to to say 50kms is a sprint, or I can’t wait for my weekly marathon. It became such a part of me that it slowly reduced the enormity of what I wanted to accomplish and was just another big adventure.

I say with my whole heart, that the Beara Way Ultra is truly one of the most spectacular events that I am incredibly grateful to be able to complete. This race gave me a new appreciation to how I view sport and what matters most to me. While I trained almost entirely alone, I genuinely could not have done that race without my amazing support crew. I don’t think my family will ever understand what I do, but they showed up for me and what it meant to me. In the fragility of 140kms deep into the wilderness of West Cork, there will never be a better feeling than seeing your friends randomly spawning with homemade signs, there wasn’t tears in my eyes, it was the rain, I swear.

I had 2 goals. Finish the race and enjoy it. I left a lot out there, but not enough to get in the way of appreciating what I was doing. My DNF at Wicklow Way haunted me, and was a fear to overcome that feeling of mental and physical breaking again. Being able to share my journey publicly, and turn to my stories with enthusiasm as I crossed the 120km of what I should have done in 2025, I knew I was over the line then. (Continued in comments!)

When people ask you ‘why?’ - why bother, why keep going, why keep trying, why do you do the things you do, when you ask of yourself the same things in times of doubt and adversity, you say ‘why not?’ Why would I not want to challenge myself to see how far I can go, why would I not want to be part of and give to everything the world has to offer, why would I not want to do it all?

And do it scared, do it when no when else is, do it because you feel like it, do it without waiting around for anyone else, do it differently and do it with your heart - give it your all and succeed, give it your all and learn. Don’t be afraid to be seen trying.

A career in STEM gave me the most exciting and fulfilling life I could have imagined and I was so honored to share my journey as a keynote speaker at the @iwish_ie festival this week.

I have forever been an advocate for female inclusion in STEM and will continue to do so, so that any girl can feel like she belongs, and has a space for her own aspirations to come to life.

I’m glad I stayed weird, passionate and true to myself and I hope I can inspire even just one teenager to do the same, whether that’s in STEM or just their own life in general - it’s the best way to be 🫶 Become your own role model.

Racing marathons? I guess it just runs in my jeans 🤔
@dublinmarathon

All jokes aside, an amazing experience made possible by the team at @hersport.ie - raising money for women in sport advocacy on such a brilliant course!

Sincere thanks to anyone who spotted me throughout the course - you all kept me going 🫶

This is also an official endorsement for @dunnesstores running jeans. Do NOT sleep on the performance of the wide leg, dark wash, from a professional aerodynamics perspective. No chafe, stylish, mega pocket space, it’s a done deal 🤝🤝

Back off track 🥉 at the @leicestershire_cxl league on possibly my new favourite course!

A perfect mix of everything and a fantastic field of competition to start the season. Debuting the @wheelbuilderuk @daocarbonuk wheel set which will hopefully set the standard for the rest of the league and into my first UK national series next week 🤝🤝

All smiles, always 🫶

Workin’, Trainin’, Car fixin’, Racin’ @wat_kitchen making my life so much easier with their Protein Bites range for snacks and meals! #ad

Big fan of the Katsu and Green Curry flavours with chicken and vegetarian options, and I love having an alternative to the usual sweet flavoured protein and recovery options.

Some large weeks coming up that I’m glad to have food sorted for me in between sessions, meeting and just life in general 😎😎

Top 10 in the World 🤯 possibly the first and last person in my bloodline to take part in a @bromptonbicycle @bromptonunitedkingdom World Championship

The most fun at the coolest bike event I’ve ever competed in. Some serious racing at @leevalleyvp with a red lines sprint finish. My aerodynamics and 3 gears ( that all became 1 ) were no match to the amazing athletes in the sparkliest suits and costumes on the day. Proud to represent the green white and gold on possibly one of the oldest bikes in the peloton #irishpride 🤝😤🇮🇪

Just know that I’m perpetually life training - even if I’m showing up in a suit and tie, or business casual, I am ALways ready to throw hands. Will be back next year fully optimised 😎

Real-road aero testing, validated in the conditions you actually race in.

A WattShop field test uses the @streamlinesaero Cirrus system to validate controlled-environment aero results on the road, providing a direct measure of how a setup performs in real-world conditions.

Ride repeatable out-and-back or loop runs while holding position and power, with Cirrus measuring the key variables that influence drag — including air speed, wind angle, speed, elevation and rider position — and scientifically normalising the data to resolve CdA run by run.

With measurement accuracy to within around 2 watts at 45 km/h (~1%), we can quickly compare positions, equipment setups and changes in real-world conditions.

It’s an ideal first step into aero testing, a cost-efficient route to a full optimisation, or a way to validate and monitor a setup between sessions.

Available worldwide - link in bio for more info!
