International Human Powered Vehicle Association http://www.ihpva.org/ provides different races since year 1975. Human muscles must be the only propulsion of vehicles. The land IHPVA record holder is "the fastest man on earth", so it is big chance for riders and designers. The fastest are fully faired recumbent bikes (minimal frontal area and minimal coefficient of air-drag resistance). 

Athletes power the most energy-efficient vehicles in existence in Battle Mountain, Nevada, where the world record surpassed 70-MPH in 2000 and 80-MPH in 2001. Athletes accelerate over 5.1 miles of desert highway from a standstill to top speed.

In 2003 team Eivie set the new European speed record at Battle Mountain, Nevada – Damjan Zabovnik, 109,8 km/h. Matjaž Leskovar could set a new world speed record, but unfortunately he stopped in the middle of the race. Despite the fact, that Damjan is only amateur recumbent rider, he was faster than Jason Queally, 2001 (UK) and Jan van Eiden, 2002 (GERMANY). How is it possible?
