Residents and motorists are being urged to think about any journeys they make on Sunday when many roads will be closed to accommodate the Manchester Marathon.
About 28,000 runners and 42,000 spectators are expected on the 26.2 mile route which starts at White City Circle in Trafford. It heads south towards Old Trafford and then turns back to Manchester city centre before heading south again through Stretford, Sale, Timperley and Altrincham. The route then takes runners back towards Manchester, ending on Talbot Road close to Old Trafford cricket ground.
Officials will start closing most affected roads from 3am and begin re-opening roads from 2pm as the course clears. The last closed road is expected to be re-opened at 8pm through Chorlton and Old Trafford towards the end of the course.
