Guinness certified the record as covering 1,725 miles (2,776 km) in 5 days 18 hours and 3 minutes, beating Rockett's time by 3 hours and 5 minutes. [71] On 3 September 2020, Marcia Roberts became the first female to record the journey starting at Lands End, by bike, in a time of 11 days, 13 hours & 13 minutes and set a Guinness World Record.

Dan Patch broke world speed records at least 14 times in the early 1900s. In 1905, he set a world's record for the fastest mile by a harness horse (1:55 1 ⁄ 4 – 1 minute, 55 + 1 ⁄ 4 seconds) that stood unmatched for over 30 years. Unofficially, Dan Patch broke this record in 1906 with a clocking of 1:55.
A replica of the 1920 Indian (with half the exterior removed to show detail) that Burt Munro used to set his record in 1967. Munro's Indian Scout was an early model, the 627th Scout to leave the American factory. [7] The bike had an original top speed of 55 mph (89 km/h), [2] but this did not satisfy Munro, so in 1926 he began to modify the bike.
Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).
The time for the race was not only a record, it was the fastest 1 + 1 ⁄ 2 miles on dirt in history, 2:24 flat, breaking by more than two seconds the track and stakes record of 2:26 3 ⁄ 5 set 16 years earlier by Gallant Man. [77] Secretariat's record still stands as an American record on the dirt. [81]
The distance used for calculating the overall speed record is usually the distance in a straight line. [2] In the case of man-powered races, overall speed record doesn't always reflect the best performance. It is highly dependent on technological advantages generating the speed of the craft, vessel or vehicle. [3]
