The 40.8 mile option includes an additional forest section that passes The Major Oak. The route is way marked with tape and arrows, marshals are placed at aid stations and first aid medics will be available on course. Aid stations and approximate mile points are provided for both distances and the only enforced cut off is 10.5 hours at the A614 aid station; competitors must stop there if there is not sufficient time to complete the remaining 7 miles. Additional rules: walkers are not permitted, pacers are not allowed, crews may not use the aid stations, no drop bags, and up to 20 canicross runners are allowed.
