    Condition of the course and race cancellation

    The course is safe, albeit hilly, however in the event of a deluge or snow, prior to or during the event, things could get a little slippery on some of the off-road sections.

    Please take extra care on the off-road sections and be mindful of other runners.

    We regret that we cannot offer refunds if the race is cancelled due to extreme conditions as we will have already incurred all our running costs. As we organise the race to support local and national charities we ask for your understanding and support.

    The likelihood of the race being cancelled due to extreme conditions in June is about as likely as a smooth Brexit but you never know.
