The current hour record for men is held by Sir Bradley Wiggins with a distance of 54.526km (33.881 miles), set on June 7, 2015. For women, it’s held by Vittoria Bussi with a distance of 48.007km (29.83 miles), set on September 13, 2018.

Check out the full article on Wired.com, which dives into some of the how, why and what of the current hour record attempts and tech. And you can dig into the history of the hour record on Wikipedia here.
