So all does not begin well for Scotsman Chris Hoy as he makes his attempt to break Arnaud Tournant's world record for the kilo. By fractions of a second - something only possible to measure with today's technology - Hoy falls outside the Frenchman's 7 year old time.
Given the travel problems that have beset Hoy on his journey to Bolivia, I am stunned that he was even in fit state to make an attempt on the record on Saturday (Bolivian time). What should have been a straight-forward journey became complicated by delays caused by unfavourable weather conditions - Latin American fog frustrates sporting excellence could easily be another headline coming so soon after the chaos in Argentina for the rally-drivers.
As I write, I understand that Chris will be going for it again tomorrow, and maybe, tomorrow and tomorrow until he breaks through the barrier. How his body will stand up to this is a real journey into the unknown, and whether he will be in a state to attack the 200m and 500m in subsequent days, must now be in doubt.
What is in no doubt is that a time of 59.103 seconds when not fully fit and properly prepared for the kilo is stunning.
