Thousands of spectators are expected to flood into Sheffield city centre for an elite cycling event.
Top-class cyclists are preparing to descend on the city for the annual Sheffield Hallam University Grand Prix tomorrow.
Motorists and travellers were today reminded there will be some disruption on the day, starting as early as 11am.
Roads along the route will be closed from 5.15pm to 10.30pm and there will also be some bus stop changes.
The Sheffield Grand Prix is the penultimate round of the British Cycling Elite Circuit Race Series and will incorporate a third and fourth category support race open to men and women riders.
Coun Isobel Bowler, Sheffield Council cabinet member for neighbourhoods, said: “This iconic event is always spectacular to watch, as some of the best cyclists in the UK go head-to-head on the streets of Sheffield.
“It follows on from the successful Allez Allez Sheffield weekend of cycling earlier this month. We hope those who were inspired by the Côte de Wincobank hill climb and Sky Ride Sheffield will come along tomorrow and watch these elite cyclists in action. Who knows, we may inspire the next Sheffield-born champion.”
The first race will start at 7pm and the Sheffield Hallam University Grand Prix begins at 8.15pm, with some of the country’s leading professional riders racing around the city centre circuit for just over an hour.
Participants include Erick Rowsell, who finished eighth in the inaugural Tour de Yorkshire earlier this year, Richard Handley, who finished 10th in the race, and Karol Domagalski, who competed in the Vuelta a España, one of cycling’s most prestigious races, known as a Grand Tour, last year.
Each lap of just over 1.4 kilometres includes a cobbled section and sweeps past landmarks such as the Crucible Theatre and Sheffield Town Hall.
The racers begin at Pinstone Street, before travelling on to Furnival Gate, turning left on to Arundel Gate, up Norfolk Street and on to the cobbled section of Surrey Street.
Marc Etches, event director, said: “The Grand Prix is a unique opportunity to enhance the continuing legacy and profile of cycling in Sheffield, thanks to the Tour de France Grand Départ last year and more recently Allez Allez Sheffield, which got more than 5,000 people on their bikes.
“This event will be another exciting opportunity for cycling enthusiasts and a thrilling night of entertainment for all.”
