How did I fuel Project TENacity? 🔋
In short, I ate everything I could, whenever I could…
But I want to focus on those three key principles:
1) Calories are king.
On a day-to-day basis I would of course be much more methodical with macros, micro-nutrition, timing, and volume - but the aim of this project was simple: keep the furnace lit 🔥
So, nothing was off limits, the overarching principle was consume energy to try and balance what was being used (which I did my absolute best to, but nonetheless ended up in a huge net deficit 🪫)
2) Bottes/hr
This was my foundation: 1 bottle/hr, non-negotiable.
750ml of water, mixed with 4 scoops of Hydroload - every hour throughout the bike and run, and sipped on either side of the swim.
This covered a decent amount of carbs, my sodium, and my water intake requirements.
The team were well briefed on this, and we did a solid job of keeping this the whole way through.
3) Convenience when needed, not as default.
Unlike any other ‘race’ day, I wasn’t optimising for speed and convenience, but rather, sustainability.
So the aim was always to rely as much as I could on whole foods for the sake of variety, satiation, morale, and digestion.
This meant I only had 8 gels the whole project, which I relied upon when I didn’t want to break stride but needed to grab something quickly from the team - the opposite to how I would normally approach an Ironman distance, but this wasn’t normal for me 😂
Overall, we got the job done, and whilst I on paper should have eaten more, I think we struck as good a balance as we could - with only one day causing digestive issues (but I was also on almost zero sleep that day, which probably didn’t help…)
Hydroloads of calories, consumed, and used 🤝

Making the impossible, possible. 10 iron distances, 10 days, 10 cities.
Completing this challenge for the Fergus who, ten years ago to this day, attempted to take his own life — and is now doing everything he can to raise awareness for men’s mental health, to start conversations, and to remind others that they are never alone.
This is more than endurance. This is resilience, growth, and purpose.
We are so proud of you @ferguscrawley ❤️

Day 7 of 10. 10 iron distances, 10 days, 10 cities.
16.8 miles in the water🏊, 784 miles on the bike🚴and 183.4 miles on foot so far🏃
Exhaustion has settled, doubts continue but one thing remains… the ability to keep going even when things feel broken. The end goal? To open up conversations surrounding men’s mental health.
Three more days. Not because it’s manageable but because it’s important.
