2. Olympic treble
Perhaps one of the most outstanding marathons ever was Emil Zatopek’s win in the 1952 Helsinki Olympics marathon. This was off the back of gold medals in the 10,000m and 5,000m, completing a truly remarkable treble which is unlikely ever to be repeated.
3. East African dominance

4. Precise marathon distance
The marathon distance only became 26.2 miles during the 1908 London Olympics. Queen Alexandra requested that the distance was adjusted so the royal household could see the race from Windsor Castle. Prior to this - from 1896 to 1908 marathons of approximately 25 miles were held.

8. Wheelchair World Record

Mars sponsored the London marathon between ’84 and ’88. They provided free Mars bars in the finish area – possibly not the perfect recovery food!
