TCS London Marathon 2025

Running for GOSH – Our Biggest Challenge Yet!

The London Marathon 2025 is more than just a race—it's a mission. This year, we're taking on the ultimate running challenge to raise vital funds for Great Ormond Street Hospital (GOSH)
For me, Dan Mann, every mile we run, every step we take, is in honour of the hospital that has given so much to our daughter, Ruby, and countless other children. That’s why I setup Run with Ruby

Why This Race Matters

The London Marathon is one of the world's most iconic races, spanning 26.2 miles through the heart of the capital. For me, this isn’t just another run — it’s the biggest challenge I've ever faced.
Last year, running the London Landmarks Half Marathon felt like an impossible feat. I doubted myself, feared failure, and questioned whether I could do it. But the incredible support and purpose behind running for GOSH pushed me past my limits. Now, it’s time to take it even further.

A Personal Journey with a Bigger Purpose

My journey with running started not as a hobby, but as a way to give back.
Ruby, our daughter, has been under the care of GOSH since birth, undergoing multiple open-heart surgeries before her first birthday. The care, dedication, and expertise of GOSH saved her life—and now it’s our turn to give back. By taking on the London Marathon, we’re not just running for Ruby but for all the children and families who rely on GOSH.

I’ve got my bib number – it’s official.

Everyone sees the bib number and race day smiles — but no one talks about the months leading up to the marathon.

The late nights. The freezing rain. The missed plans because you’ve got a long run. The injuries that knock you back just when you’re getting into a rhythm. The chest infections that wipe out a week and leave you feeling like you’re starting from scratch.

Training for a marathon isn’t a straight line. It’s progress, setbacks, and the stubborn decision to keep going anyway.

It’s not just 26.2 miles on the day — it’s hundreds of miles in the dark, in the cold, and when no one’s watching. And I’ve felt every one of them.

I’ll be starting in Green Wave 4, around 11am.

It feels like a privilege to be part of that start zone — a smaller group where a lot of the charity runners and even a few celebs set off.

We’re not at the front with the elites, but we’re running with purpose. Everyone in that wave has a story, a reason, and something driving them.

I’m proud to be one of them.

For me this has been the most difficult challenge I’ve endured (so far), with me wanting to quit training more times than I can count.

But your donations, your support and thinking what incredible work Great Ormond Street has done for Ruby and others keeps me going.

3 days to go!

Nerves are really starting to settle in, after picking up my Bib Number.

I decided to head to the London Excel Arena early to avoid the madness Saturday.

Suprisingly, alot of other runners were on the trains from Norfolk – when speaking to them, it was great to hear that “maranoia” was being shared.

On arriving, I went straight to the bib collection points, and had this wave of emotion come over me. It all suddenly became very real!

The lady took my QR code, and asked how I was doing, and if I was looking forward to Race Day.

With my eyes welling up, I simply replied, “It’s been really tough, but I’m as ready as I can be.”

2 days to go!

It's London Marathon eve eve. We are getting our stuff ready for travelling tomorrow.

Today, I’m feeling alot more hopeful. After the Expo experience yesterday, and seeing everyone is in the same boat – I realised I’m not alone.

Some people have travelled the world for years running, and only just got into the  London Marathon.

On the flip side, there are people like me – their first-ever Marathon.

I feel truly blessed to have this opportunity. And everyone taking part is going thorugh the same motions. We ask ourselves questions: Can I manage this injury? What if I don’t carb-up perfectly? How hot is it going to be on the day?

Whatever the weather – We Run Together!
