PICTURE SPECIAL: Chichester Corporate Challenge off to flyer
A record number of entrants made for a packed city centre for the opening race night in this year's series of three.
Cold, clear conditions were just right for the hundreds of runners who tackled a course starting and finishing outside the Assembly Rooms in North Street.
There were seven separate races, with primary-school pupils, secondary pupils and seniors all taking their turns to impress.
