I must take issue with the earlier comment that Cracknell is a better bike handler than Romero. I was the start timekeeper and observer in the first following vehicle till Preston.Romero started on the front and they changed tandems about every 3 hours.It was very apparent that she was a very good bike handler taking a better line through corners,a straighter line generally and a better choice of gear.As the ride progressed Cracknell seemed to improve in his ability to ride in a straight line.
