The event will raise money for Cancer Research UK, with £1 from every entry going to the charity.  Cancer Research UK relies almost entirely on public donations and aims to conquer cancer through world-class research.

This is the 15th year the event, sponsored by Accenture, has run and organisers are hoping to repeat last year's success by attracting over 500 runners.

The event is open to all, and it's a great opportunity to meet new people and get fit at the same time.  All runners will receive a goody bag.

Steve Brindley, Athletic Union (AU) Chair, said: 'This event continues to grow from strength to strength and it's always a really fun day.  It gives students the chance to compete or simply participate alongside the wider Bristol community.

'I am pleased we have been able to re-introduce the charity angle for this year's event.'

The event is open to individual and team entries.  Entry costs, in advance, are: half marathon - individual, £6; teams of four,  £19.  5k challenge - individual, £4; teams of four, £12.

Entry forms, dietary advice and training information are available from the AU office, Students' Union, Queen's Road, the Indoor Sports Centre, Tyndall Avenue, Coombe Dingle Sports Complex, Coombe Lane or they can be downloaded from www.bristolau.co.uk.

Half marathon entrants must be aged 17 or over.

The half marathon and 5k challenge starts at 1 pm.

The 5k challenge course will be run within Coombe Dingle Sports Complex. The Half marathon course is two laps of a set course starting from Coombe Dingle Sports Complex and looping around the Downs and through Wills Hall.
