Philippa and her husband Jon chose to take on the Trek to Machu Picchu to celebrate Philippa's all-clear after nine years of cancer treatment, raising over £6,600 for The Royal Marsden Cancer Charity.
"I wanted to do something big and challenging to mark this point in my life and push myself out of my comfort zone! I have always wanted to go to Machu Picchu, so now was my chance to take on a challenge and raise funds for this very important charity.
"Trekking in the Andes is breath-taking. Seeing Machu Picchu for the first time is something I will never forget. It meant so much to me, thinking of all my sponsors and those who hadn’t made it through cancer treatment, I felt so lucky to be there."
Thanks to supporters like Philippa and Jon, we continue to fund vital research and care for all those affected by cancer.
We’d love to keep you up to date with inspiring stories, the latest breakthroughs, and ways you can make a difference.
