Peto was on
the Move podcast. It wasn't very interesting until about minute 40 where he started talking about how the peloton has changed since he started.
I couldn't quite tell if he was describing real changes, or it was actually that his perspective changed, because he said the young riders were taking too many risks, and that sounds like a very typical response to aging as one's own risk-taking behavior diminishes. But he also claimed the speeds were up without any reasonable explanation.
Overall the interview made me a little sad because he seemed old and tired and that hotel room he sat in was a bit dreary to look at. The hosts kept acting like Peter had somewhere else to be, but in reality it was Hincapie who had cut out to take his kids to school.
I think what Sagan lacked in his career was a big rival (the Canc to his Boonen, the Wout to his MVDP) to both elevate his game and take some of the eyes off his back wheel.
