I've been struggling to get an accurate picture of how Steve is progressing, with varying distances and the distortion caused by that extremely long first day. It's so much easier to with Amanda's approach.
Having finally established my own spreadsheet, I think that for the moment a really useful number to look at is average daily distance excluding the first day, which can be thought of as the sustainable daily average. At the moment this is 226.1 (my figure) which clearly won't win the prize, but it isn't far off and as long as the number is edging upwards, the campaign looks to be in good health. By the end of the summer I'd say he needs to be averaging 240, and by that time the influence of the first day will be negligible.
On the Amanda front, her rolling 30-day total is now all but 7400 miles, and still she hasn't formally started a month record attempt, as far as I know. You do have to wonder how many hours a day she can ride in the final month when she has absolutely nothing to lose.
