What is The Big Half?

The Big Half is a brand-new world-class mass participation event, organised by London Marathon Events Ltd, which features a half marathon (13.1 miles) and other events held on closed roads in London.

The Big Half is more than just an event; this is a campaign. This unique event will demonstrate how sport and community can get together to inspire social change, create social cohesion and improve health and wellbeing.

Its guiding principle is to be 'Truly Global yet Uniquely Local.' The Big Half will be much more than a mass participation running event with the world’s best athletes and thousands of mass runners. It will be a street party of epic proportions and it aims to inspire participation from a variety of socio-economic groups, faiths, ages, ethnicities and to become the first sports event whose participants truly represent London’s diverse population.

When is it?

The Big Half will take place on Sunday 4 March 2018.

What are the events in The Big Half?

The Big Half will be the annual half marathon every elite runner will want to win, just weeks ahead of the Virgin Money London Marathon. In addition to the global superstars of distance running, the thousands of mass runners will inspire spectators to take up the challenge in future years. The course will be ratified for world records.

The Big Relay will be exclusively open to community groups from the host boroughs of Southwark, Lewisham, Tower Hamlets and Greenwich. Participants will be able to run in teams of four, each person will run one leg of The Big Relay – over distances ranging from one mile to five miles. Full details will be available in due course.

The Little Half will be held on a 2.4 mile route from Southwark Park to the stunning finish line by the Cutty Sark in Greenwich. Full details will be available in due course.

The Big Festival

Greenwich will be the place to be on Sunday 4 March as The Big Festival celebrates London’s diversity with a huge range of food, music and entertainment. There will be local traders serving food from around the world, music playing throughout the day, performances from community groups and fun activities and fitness classes for the whole family to enjoy. More information will be available soon.
