Seems like we're just beginning to realise our human potential. On 20 July, fortysomething Greg Kolodziejzyk travelled 1046.94 km (650.538 miles) in 24 hours, in his bullet-shaped human powered vehicle (HPV), Critical Power beating the previous mark of 1021.36 km (634.644 miles) set in 1995.

Last month, the human powered hour record fell when 50-year-old Fred Markham broke the 85,4 km mark at the 2006 Dempsey-MacCready One Hour Record Attempts on the Nissan track in Arizona.

Ergonomic design of these recumbent bikes is a major factor where speed is concerned, but it will be interesting to see what happens when some young legs get behind the wheels for these HPV records.
