TCS London Marathon
Take on one of the world’s most iconic marathons.
The TCS London Marathon takes you on an unforgettable 26.2-mile journey through the capital, from Greenwich to the famous finish line on The Mall. Along the way, you’ll experience some of London’s best-known landmarks, incredible crowd support, cheer zones, live music and an atmosphere that will carry you towards the finish line.
Whether it’s your first marathon or the challenge you’ve always dreamed of taking on, this is your chance to be part of an extraordinary day while doing something incredible for families facing childhood cancer or a life-challenging condition.
By running for Momentum, every step you take and every pound you raise will help us be there for families through serious illness and bereavement, making sure no family has to face it alone.
London Landmarks Half Marathon
Not your average half marathon.
From iconic cultural landmarks and historic streets to some of London’s quirky and lesser-known sights, the London Landmarks Half Marathon is a brilliant way to experience the capital.
Starting on Pall Mall and finishing near Downing Street, you’ll join thousands of runners for 13.1 miles through the heart of London. Along the way, live music, theatrical performances and plenty of enthusiastic supporters create an incredible atmosphere from start to finish.
This is far more than your average half marathon. It’s a fun-filled celebration of London, packed with sights, surprises and entertainment to keep you going every step of the way.
Take on the challenge for Momentum and make every mile count for families of seriously ill children and those navigating bereavement.
