The Bob Graham Round is an epic fell running challenge in the English Lake District. The Round is named after Bob Graham (1889–1966), a Keswick guest-house owner, who was the first individual to complete a traverse of all 42 major Lakeland fells within a 24-hour period.

The Round was first repeated, in a better time, in 1960 by Alan Heaton. Since then over 2000 individuals have completed the Round with the fastest time, until this year, being Billy Bland's record of 13hr 53m which had stood for 36 years.

On July 8, 2018, with the help of the fell running community of England's Lake District, mountain athlete Kilian Jornet completed the legendary Round in just 12 hours 52 minutes. This is the story of his effort.
