10 Years. 26 Miles. One Incredible Cause.

In honour of 10 years of My Peak Challenge, Sam is running the London Marathon 2025 — and he’s dedicating every mile to Blood Cancer UK, our official charity partner for this milestone year.

This run is about more than just crossing a finish line. It’s about pushing limits, celebrating resilience, and standing up for those impacted by blood cancer. Every mile Sam runs is a reminder that together we can turn challenges into change.

You can sponsor a mile to fuel Sam’s run and help us raise life-changing funds for research, support, and hope.

Donate $10 to sponsor those exciting first miles 1-5

Donate $15 to sponsor Sam getting into his stride in miles 6-10

Donate $20 to sponsor the trickier miles 11-15

Donate $25 to sponsor Sam through those tough miles 16-20

Whether it’s mile 3 or mile 23, your donation carries him forward — and brings us all closer to beating blood cancer sooner.

We'll shout out Peakers on socials as Sam progresses on the day, and you may even get a thank you from Sam himself!

1 in 3 people don’t survive their blood cancer and we lose them in the first five years after diagnosis.

Too many people are dying from the most complex and aggressive forms of blood cancer - blood cancers that are the hardest to treat.

We believe it’s possible to achieve significant shifts in survival, by making sure that all patients have access to the right drug at the right time.

Our focus on the hardest to treat blood cancers will accelerate progress towards our goal of radical improvements in outcomes for these patients and bring forward the day when we beat blood cancer.

Join us in celebrating a decade of purpose, progress, and Peaker power.
