All of this is true, but we are talking about a consistency that is down to tenths of a second per lap. And I think it is easy to drift off target over the course of one hour. Just changing your cadence by 1 rpm could mean the difference between breaking the record, blowing up or making the record. And doing that for 1 hour. That’s what amazed me when I watched Alex Dowsett’s attempt, too, the consistency of pros is off the charts.
