10:30 ESST - Scheduled start

The record (we think!) is 43.08292 km, set by Cornelia Van Oosten-Hage on September 16, 1978. Can Anna Wilson better this on her "standard" track bike? It is a steel pan-brown Perkins (Columbus frame) on a 92 inch gear, and standard unbladed spoked wheels (box section rims). The tires are Continentals.

She has just started. Her schedule is 25 seconds for the first lap (250m laps), then 20.85 seconds average for the remainder. She plans to ride close to 21 seconds for the first 15 minutes, then step it up a little. A rough calculation over the hour gives 43.165 kilometres for this schedule.

10:40 ESST

In the first three laps, she was on 20.6 seconds per lap, but she is settling down now into a rhythm. This is the first serious hour record attempt for many years on such a bike, and it will be an interesting benchmark, should she complete it.

11:10 ESST

Wilson is still looking great with 20 minutes to go and is being urged on by the crowd. The average after 40 minutes is 43.4 km/h. This equals 116 laps at 20.7 seconds per lap.

A little more on the gear ratio: A 92 inch gear was chosen to correspond with a 99 rpm pedalling cadence.

She actually finished the hour fractionally after the finish line of lap 174, but the exact distance was be calculated on the basis of her subsquent lap: 43.501 kilometres. The UCI may take up to 3 weeks to ratify the attempt, dependent on the drug test and the commissaire's track report. spoke with the UCI commissaire, Karen O'Callaghan after the attempt to discuss the technical specifications of the bike in more detail.
