This is one of the world’s most iconic marathons with around 45,000 incredible runners per year pounding the streets of London for good causes.

Cosmic only have a certain amount of places we can offer each year but will try to accommodate as best we can. We ask all our successful applicants to raise a minimum of £2,000 for us and pay a registration fee of £50.00.

Unfortunately, all of our places have been filled for the 2025 London Marathon.

Cosmic have cheer stations each year where we get the chance to support our runners on the day, greeting them with a smile and cheering them on to the finish line! We are always looking for new volunteers to join us!

If you have any questions, would like to know about volunteering opportunities or are interested in running the marathon for Cosmic in the future, please contact us on info@cosmiccharity.org.uk.

Charlotte Creevy

On the 19th October 2022 my identical twin boys, Sylvester & Seth, were born. On the 1st of November, I took Seth to Whipps Cross A&E as he wasn’t his usual self. In the early hours of the following morning, I was woken by the emergency alarm and a Dr calling for the Resus trolley. Seth had stopped breathing. He required CPR. Given this, he was intubated and ventilated. Seth was transferred to St Mary’s Hospital PICU for further management.

In total, Seth was in PICU for 3 (very long) weeks, receiving respiratory support while fighting off 3 viruses. While the doctors, nurses and physios did everything to save our son, Cosmic did everything to support my husband and I. Amongst other things, they put us up in their hotel within the hospital, meaning we could be with Seth as much as possible. It was an extremely tough time, given I also had another newborn son and a one year old daughter to be cared for.

I will forever be grateful for the, much needed, care and support we received during this time. The least I can do to demonstrate my gratitude is run the London Marathon! Nothing will be as hard as those 3 weeks. I want to raise as much money as possible, so Cosmic can continue their amazing work.

Eulanda Griffith

Hi, my name is Eulanda and I have decided to run to the London Marathon 2025 to support Cosmic Charity. Cosmic is a charity very close to my heart because they were able to support me at a time when my daughter became very unwell due to sepsis. This was a life changing unfortunate event that affected my family as a whole and during the three months that I spent in hospital with my daughter Cosmic supported me throughout in many ways. The charity is very important to me and running the marathon is my way of trying to give something back whilst being able to help other families with babies or young children in intensive care. Thank you x

Hannah Howell

I’m running this marathon in honour of my nephew, Noah who was born prematurely and sadly passed away in August this year after spending 138 days in the NICU across two different hospitals including Queen Charlotte’s. His life, though brief, has had a profound impact on the whole family and I want to do everything I can to support other families facing the challenges of prematurity and many other issues that result in children ending up in the NICU.

A baby or child being in intensive care is unimaginable for many of us parents however NICU and PICU is the reality for millions of babies and families every year, with many requiring intensive medical care to survive and thrive. Sadly, not all are as fortunate, and the emotional toll on families is unimaginable. Through this run, I hope to raise both awareness and funds for Cosmic Charity, a charity that provides vital support to babies and families that are in the NICU and PICU at St Mary’s and Queen Charlotte’s Hospital London. They go above and beyond what the NHS can afford purchasing vital state of the art equipment, providing training for health professionals, funding a programme of groundbreaking research into life-threatening diseases and supporting families through one of the most difficult times in their life with one to one support, advice, counselling, accommodation for parents.

My goal is to fundraise to help provide the care that these babies and children need and offer support to families who, like mine, know the heartache of losing a child.

Running this marathon is my way of honouring Noah and ensuring his memory lives on by helping other babies and families in need. Together, we can contribute to giving these babies and children a fighting chance and support those going through the toughest battle of their lives.

Thank you for your support, Hannah

Lucy Pender

I’m thrilled to be running the London Marathon 2025 for Cosmic – having found out about Cosmic through a close friend of mine several years ago now and having attended fundraising events in the past, I knew it was only right that I should apply to run the London Marathon 2025 and I was so excited to be offered a position. Having only started running less than a year ago, I thought I would throw myself into the deep end and completely out of my comfort zone and apply for the London Marathon 2025!

Manni Rai

Hi, I’m Manni. I first started doing the London Marathon for Cosmic way back in 2014.

This will now be my fifth marathon for Cosmic and I’m both excited and honoured to be given the opportunity to do it again for this fantastic cause which helps so many families at such difficult times.

Ironically I’m not a fan of running, but a few hours of pain are more than worth it to support such an incredible cause and team which makes such a huge impact on so many lives.

And of course I get to create and wear another costume which is my side hobby! This year I was the Mandalorian, and I’m super excited to get started with my next creation for 2025 and run for Team Cosmic!

Any donations to make the pain of 26.2 miles in a very uncomfortable costume would be warmly welcomed below! Thank you

Matt Dadson

I am Matt Dadson. I will be running for the first time for Cosmic in the 2025 London marathon. For over 25 years my mum has worked as a Senior Sister on the Paediatric Intensive Care Unit (PICU) at St Mary’s hospital caring for critically ill children and babies. This means I have quite literally grown up supporting Cosmic.

Megan Leaning

Hello! My name is Meg, and I am thrilled to run the London Marathon in support of COSMIC. This race has always been at the top of my bucket list, and I’m so excited to take on this challenge, proving to myself that I can achieve it.

I have worked as a nurse on PICU for almost three years where I have witnessed firsthand the impact of Cosmic’s work. Cosmic is a vital charity that supports babies, children, and families in the paediatric and neonatal intensive care units at Imperial College Healthcare. They also support the dedicated medical and nursing staff caring for them which I have found incredibly beneficial and uplifting during difficult days on the unit.

The charity not only provides essential accommodation for parents during their child’s treatment but also funds critical equipment that goes beyond NHS provisions. Knowing that parents can stay close to their children during such difficult times makes a profound difference.

I would be incredibly grateful for any donations to this wonderful charity. Your support will help Cosmic continue to make a positive impact on the lives of children and families in need and continue to raise morals for the hard working PICU and NICU teams. Thank you for your generosity!

Neil Bolger

Hi, my name is Neil and doing the London Marathon has been on my bucket list for several years

My son is a nurse in paediatric intensive care at St Mary’s hospital and as well as being incredibly proud of him and the work he does, I am also aware of how vital the support is provided by Cosmic for both the staff and the parents there. What better way to show him how proud I am of him in his career while running and raising money for this this worthy charity who make such a difference to people’s lives

Paul Ridley

Hi I’m Paul, I’m running the London Marathon for the 2nd time for Cosmic in loving memory of my daughter Abigail who sadly past away in 2022.

I wanted to give something back to St Mary’s Hospital. To show my appreciation as in 2011 Abigail was admitted with various infections and we were told she was unlikely to make it through the night. 6 weeks later Abigail had pulled through thanks to amazing care she received at St. Mary’s from all the wonderful Doctors, nurses and support staff.

It is for this reasons that I feel incredibly passionate about running the marathon and raising monies for this wonderful charity. I would greatly appreciate any donations to help me in getting over that finish line!

Tara Bloom

Hi, I’m Tara! I’ve wanted to raise money for Cosmic ever since my son Ezra was born prematurely in 2021 and benefited from their incredible services in the NICU, as did my niece Leni 2 years later.

I have seen first-hand just how incredible the nurses and doctors are. I’ve also always had a huge desire to run the marathon, so when this opportunity arose to raise money for Cosmic I was so excited. Currently loving the running journey!

Tate Burns

My name is Tate, London 2025 will be my first marathon I started to get into running around a year ago, I have completed two half marathons and am excited to face the challenge of completing a full one!

I have chosen to run for cosmic as they are a fantastic charity and their dedicated team helped to support my brother in laws family when he was diagnosed with meningococcal septicaemia at 9 months old.

I’m looking forward to help being able to give something back to the charity.

Tilly Todd

I’ve always wanted to challenge myself to run a marathon and when I found out that Cosmic had some spaces available I jumped at the chance.

Cosmic is a charity very close to my heart as they saved my life. When I was three years old I was rushed to intensive care. I had an ordinary case of chickenpox, which developed complications leading to a serious case of pneumonia, which blocked all of one lung and half of the other, giving me me hours to live. This then led into an infection of the pleura which had to be removed, along with having Osteomyelitis and Sepsis. I was in a medically induced coma for a month – amazingly, I made a full recovery and Cosmic cared for me and my family throughout it all.

Now at 28 years old, I am fit and healthy and exercise is part of my daily routine. I have always enjoyed running but have never challenged myself to a marathon, so this is an exciting (and quite terrifying) experience! Running it for Cosmic is such an amazing way to be able to give back and such great proof of how brilliant their care had been in enabling me to be fit and fighting! Hopefully I can run it in a good time (with lots of training!!) whilst being able to raise money for an amazing charity.
