What is The Big Half?

Join Team Asthma UK for a half marathon on closed roads in the centre of London. The Big Half will give you a taster of the London Marathon as it follows the official cours of the longer race, starting at London Bridge and finishing in Greenwich. It is then topped off with a festival in Greenwich Park to end the event.
