Your circular tally card and race number (race numbers were only introduced in the last few years) are given to you after you have registered and passed all the kit check requirements. Although there is talk of a special 50th anniversary map for this event, it has always been a case of supplying your own OS maps to cover the whole route, and it would be a good idea to take your own just in case the event map does not materialise. The handbook really does have all the information you need. Take the time to read it thoroughly and make sure you have everything withyou on the day, or risk not being allowed to start.
