The Big Half  is a vibrant, inclusive half marathon with a fun, festival atmosphere.

This is an incredible opportunity to run part of the iconic London Marathon course on fully closed roads. The 13.1 mile course weaves through London from Tower Bridge to the iconic Cutty Sark in Greenwich.

To secure your place you simply need to pay a registration fee of £35 and commit to raising a minimum of £350 in sponsorship. We'll provide you with plenty of fundraising tips along the way and a very smart RNOH Charity running vest!
