Just been reading this as a follow up to a magazine snippet.

And they only get a 4 mile acceleration zone, I'd be buggered by then
let alone breaking a record over the course.

During the week of September 10th through September 15th 2012, cyclists
from around the world will gather on SR305 outside of Battle Mountain,
Nevada for the 13th consecutive year of racing on what is arguably the
straightest, flattest, and smoothest road surface in the world.

The 4,619ft (1,408m) altitude road allows riders an acceleration zone of
over 4 miles, enabling them to reach their maximum velocity before being
timed over a 200 meter distance. The section of the road used for this
event was newly refinished in 2009, with a smooth surface specially
prepared for human powered cycle racing by the Nevada Department of
Transportation.


Current WHPSC Records:
In 2009, Sam Whittingham broke his own record again for a human powered
speed of 82.819 MPH!
In 2010, Barbara Buatois broke her own record, with a women's human
powered speed of 75.69 MPH.
In 2011, Greg Westlake broke his own record with an arm powered world
speed record of 45.68 MPH.
