Join Team Asthma UK for this brand-new half marathon on closed roads in the centre of London. The race starts at London Bridge and finishes in Greenwich. It is then topped off with a festival in Greenwich Park to end the event.

The Big Half gives you a taster of the London Marathon as it follows the official course which is happening just a few weeks after this half marathon.

Official places and residential places sold out very quickly, but Asthma UK still have a very limited number of entries. Sign up today to guarantee your place in one of London's newest and most exciting runs.
