Someone has made a documentary about Alf Engers, the King of Shorter Distance time trialling (first person to go over 30mph in a 25, back in 1978, before disc wheels, aero bars etc).
There was a screening in front of an audience at the weekend, with a Q&A session with the legend himself.
Here is a report (some good insights into time trialling, even if you are not interested in the history!):
