The fastest recorded time for running the 874-mile route between John O’Groats and Land’s End—commonly known as the Jogle—stands at nine days, two hours, and 26 minutes, set by Andrew Rivett between May 4 and 13, 2002. Guinness World Records continues to recognize Rivett's performance as the official "pre-GPS" record, noting that he averaged approximately 90 miles per day for most of the run and maintained about 18 hours of running daily.

However, Rivett’s record has been the subject of scrutiny and debate. His time was nearly a full day faster than the previous official best, which was ten days and two hours, set by Richard Brown. In 2018, athletics writer Will Cockerell raised questions about the validity of Rivett’s claim, citing doubts over Rivett’s previous ultra-running credentials and the evidentiary standards in place during the run. Cockerell described Rivett as "a solid club runner" whose performances declined notably beyond half-marathon distances. At the time of the 2002 run, GPS tracking was not in use, and verification relied on photographs and police officers’ signed witness statements.

In contrast, the fastest known time supported by modern tracking technology belongs to British team member Dan Lawson, who completed the run in nine days, 21 hours, and 14 minutes in August 2020. Lawson’s achievement marked the first sub-10-day completion of the route with extensive and reliable evidence.

Given this, two times are generally cited: Rivett’s record remains officially recognized but is regarded with some caution, while Lawson’s time is accepted as the fastest fully verified completion under current standards.

On the women’s side, Carla Molinaro holds the Guinness World Records title for the fastest female to complete the John O’Groats to Land’s End route, finishing in 12 days and 30 minutes in July 2020.
