Bristol: Sign Up For The City's 10k Run
People wanting to get fit for their New Year resolution are being encouraged to sign up for the 2014 Bristol 10k.
As well as giving you the excuse to get healthy, the event is also raising money for the races' official charities - Wallace & Gromit's Grand Appeal, CLIC Sargent and COCO.
Online registration for the 2014 Bristol 10k - which takes place on Sunday, May 11 - opens at midnight on New Year's Eve.
Organisers are also looking for people to become race volunteers, marshals and fundraisers.
