Police have asked drivers and cyclists to be extra careful along the marathon route on Sunday. Some roads will be closed to traffic for a while, but most will stay open.
The marathon starts in Earle Drive, next to Parksfield, at 11 a.m. Cheshire Police say that Earle Drive, Parkgate Road, The Parade, at Parkgate, and Boathouse Lane will be closed for about 25 minutes.
Merseyside police say that Telegraph Road, from its junction with Station Road as far as Montgomery Hill, Thurstaston, will be closed from 11:30 a.m. until approximately 1:30 p.m. Spectators should take this into account when planning their journey round the course, said a police spokesman.
The thing to remember is that there will be a lot of people out on Sunday - runners, motorists and spectators. We hope drivers will realise some of our difficulties and co-operate with the organisers.' said a police spokesman. 'There are bound to be delays,' he added.
Burton Road and Neston Village, on the home stretch, will not be closed to traffic, but police will be 'keeping an eye' on the situation.
'We will be out in force manning all road junctions' said a spokesman.
Cyclists are being asked to keep a safe distance from competitors, following several incidents last year when come machines went too close.
All competitors will run on the left, except where directed by the police.
Every competitor who completes the marathon course will receive a certificate bearing his/her position and finishing time. Those who do not complete the course will receive a certificate from the nearest 'feed' station, confirming the distance they did manage to cover.
