The Simplyhealth Great Bristol 10 and Half Marathon are annual events staged by Great Run, the UKs biggest mass participation events company. The half marathon returns to the city on Sunday 17 September for it’s second year as part of the Great Run series. The event comes with its own distinguished history. First staged in 1989 and known as the Bristol Half Marathon, the city centre run has become a long-held tradition in the national running calendar. Over 10,000 runners every year make this a must do event with an atmosphere second to none. The Arcadis Business Challenge at the Simplyhealth Great Bristol Half Marathon encourages local businesses to compete against their rivals on the iconic city centre course on Sunday 17 September. It’s also an opportunity for each individual organisation to encourage a healthy outlook for staff, engage in some team building and focus on charity fundraising for their chosen good cause.
