Physicists reveal that tailwinds have little effect on cycling speed
Author Martin Beer in an aerodynamic tuck, a cycling position that reduces drag. Credit: Martin Beer In the cycling world, “To Everest” means cycling up and down the same mountain, reaching a total altitude of Everest’s 8,848 metres. After a new “Everesting” bicycle record was set a few years ago, social media erupted with debate about the strong tailwind (5.5…
