I think the London Landmarks is too far away from me
London Landmarks Half Marathon is often cited as the best marathon in the UK as the event takes in historic tourist sights and stunning city views. So, why not make a full weekend of it, experiencing the iconic Palace of Westminster, a spin on the London Eye for panoramic views over the Thames or visiting one of a huge selection of museums and galleries along the South Bank including the Tate Modern.
Why run for Ovarian Cancer Action?
