First staged in 1985 by Duke Street Running Club, this race was originally based in the centre of Norwich - hence its name. Then in 1993 it moved to the Norfolk Showground on the western outskirts of the city and it's been there ever since.
The race starts and finishes within the Norfolk Showground and follows a rural single lap route through the parishes of Easton, Honingham, Colton, Barnham Broom, Marlingford and close to Easton College. The first half of the course is pretty flat with one or two little bumps in the second half. All roads along the race route are closed to through traffic while the race is in progress
