Marathon event should be dry
Runners will set off in dry but chilly temperatures on race day.
Weather forecasters are predicting sunny spells throughout the majority of Sunday, but stragglers could get wet if they are not home by 4pm, when rain is expected.
When the starter’s pistol goes off at 9.30am, temperatures are expected to reach 10 degrees, rising to highs of 13 degrees later in the afternoon.
