Access to cycle lanes impacted around the route will be maintained. Please keep an eye out for diversionary signage. Please note: printing this map on a scale less than A2 will result in a loss of clarity on road names.   

Check out our top tips for event day below:

  • Please allow for extra time when traveling on race day.
  • Open access routes (indicated in green) will be open at all times during the day. Please aim for these when navigating around the city.
  • Please take note of the road opening times indicated on the map. Many roads used by the course will be open within one or two hours of the start of the race at 10am. This will subsequently open up large areas of the city.
  • Plan your route in advance and be aware of potentially congested areas.
  • Be careful in areas of shared road use (as indicated on the map). This is where the race route directly meets open roads.
  • If you have any queries or concerns about any of the road closures detailed, please email [email protected] or phone 02921 660790
