The distances and speeds that Peary claimed to have

The distances and speeds that Peary claimed to have achieved once the last support party turned back seem incredible to many people, almost three times that which he had
accomplished up to that point. Peary’s account of a journey to the Pole and back while traveling along the direct line – the only strategy that is consistent with the time constraints that he was facing – is contradicted by Henson’s account of tortuous detours to avoid pressure ridges and open leads.
The British explorer Wally Herbert, initially a supporter of Peary, researched Peary’s records in 1989 and found that there were significant discrepancies in the explorer’s navigational records. He concluded that Peary had not reached the Pole.[10] Support for Peary came again in 2005, however, when British explorer Tom Avery and four companions recreated the outward portion of Peary’s journey w
ith replica wooden sleds and Canadian Eskimo Dog teams, reaching the North Pole in 36 days, 22 hours – nearly five hours faster than Peary. However, Avery’s fastest 5-day march was 90 nautical miles, significantly short of the 135 claimed by Peary. Avery writes on his web site t
hat “The admiration and respect which I hold for Robert Peary, Matthew Henson and the four Inuit men who ventured North in 1909, has grown enormously since we set out from Cape Columbia. Having now seen for myself how he travelled across the pack ice, I am more convinced than ever that Peary did indeed discover the North Pole.”[11]
