Fundraiser Spotlight
"I felt helpless watching the death and devastation taking place in Gaza, so I decided to raise funds for MSF by doing the 2025 Swim Serpentine. I am not a natural swimmer, so this was a proper challenge, but the swim was incredible, and I was proud to have been able to raise more than £5,000 for MSF. Thank you to all who donated”
