There is no official cut off time but after around 3hrs the roads will be re-opened and there will be limited marshals on the course. Please see results from previous years as a guide to finishing times.
Yes dogs are welcome but they must be kept on a short leash at all times so as not to impede other runners.
There are no pacers for this event. The start is divided into expected finish times so you should be able to position yourself accordingly.
