Josh shares the toughest moments, the mindset, and what the finish line means.

With less than one week to go until Josh Cullinan takes on the London to Brighton 100km Ultra Challenge on 23 May, the focus has shifted from building fitness to staying consistent, recovering well, and sharpening race-day mindset.

In this Q&A we find out what’s surprised him most on this journey, the hardest part of training and why he chose a challenge that pushes him so far outside his comfort zone as he gets ready to supports Youthful Minds and youth mental health awareness in Jersey.

 

What’s surprised you most about your journey so far?

That it’s actually happening. A year ago I couldn’t finish a 5k without stopping due to fatigue, and now I’m about to take on 100km. It really shows what you can achieve when you fully commit yourself to something.

What has been the most difficult part of training?

One of the most difficult parts of training has been managing the sheer volume each week — balancing running, weight training, and recovery swimming. It’s required a lot of discipline, and I’ve had to sacrifice a big part of my daily life to stay committed to the goal.

What made you pick this challenge in particular?

I picked this challenge because I’m drawn to things that really push me out of my comfort zone. I love a challenge that makes me doubt myself and question whether I can actually complete it.

Do you have a strategy for the race on the day?

I think a big part of this race is the mentality as much as the physical side. My strategy is to stay focused and keep my mindset positive, so I can push through whatever challenges come up on the day.

What will be going through your mind as you cross the finish line?

I think it’ll be a mix of relief, pride, and gratitude. This has been a long-term goal of mine, and crossing that finish line will make me reflect on the whole journey — from where I started to how far I’ve come. I’ll be thinking about all the people I’ve met and the bonds I’ve made along the way, as well as the lifestyle change that running has brought into my life.

With race day now fast approaching, Josh’s focus is clear: keep the mindset positive, embrace the discomfort, and push through every high and low the course brings.
