Although it is held in July, the race has on many occasions been affected by inclement weather. Navigational problems in poor visibility have often caused runners to go off course. In 1985 even Billy Bland, the course record holder and winner on several occasions, went the wrong way in the mist after Seatallan, finding himself on the wrong side of Haycock and having to go over Haycock and Scoat Fell to get back on course.
