Go the Distance. Make it Matter.

TCS London Marathon 2027

Run 26.2 miles through London and help us support families where a parent is living with an incurable cancer diagnosis.

This event is about more than running.

After a fantastic TCS London Marathon 2026, Ruth Strauss Foundation are pleased to open applications for our 2027 charity spaces.

The TCS London Marathon 2027 will take place on Sunday 25 April 2027, following the iconic 26.2-mile route through London from Blackheath to The Mall.

Applications are now closed but you can still take part in other upcoming events!

The Impact

Why Your Run Matters

Every mile you run helps families navigate one of life’s toughest tests – when a parent is living with an incurable cancer diagnosis. 

Your fundraising helps us to: 
  • Support families with emotional and practical guidance 
  • Help parents prepare their children for the future 
  • Train healthcare professionals to better support families 
  • Raise awareness of non-smoking lung cancer
