Keen cyclists are being invited to get involved in an event taking place at Chapelfield Gardens in Norwich tomorrow.

Critical Mass is a monthly bicycle ride which aims to celebrate cycling and to assert cyclists' rights on the road, and it takes place on the last Friday of every month in many cities across Europe and America.

Tomorrow evening in Norwich cyclists are being invited to meet at 6pm at the bandstand in Chapelfield Gardens.

They will then all leave the city centre park at 6.30pm and will go on a cycle ride together around the city.

Everyone is welcome to get involved with the event which aims to raise awareness of the benefits of cycling.
