I think it is unnecessary and rather disrespectful to be quite so critical of Miles.
We're not talking about an attempt at an SR, LEJOG, or RRTY, PBP/LEL or even RAAM. This is an unbelievably punishing amount of riding across an entire year, such that only a very few cyclists have even attempted it in over a century. I doubt if anyone on this forum, even the highly experienced audax riders or time triallists, can even begin to imagine what attempting this record must be like, riding day in, day out.
So please, a little more humility and respect from those commenting on any of the riders challenging for this record.
Personally, I'm supporting Miles just as much as I am Steve or Kurt. Maybe he won't break the record, we'll see. The year is not yet out.
