They do tend to put up barriers for the last few kilometers in recent years. But ISTR that it's particularly difficult to do on the Tourmalet because the street is so narrow.
Seems like they've put new asphalt on quite a few of those mountain roads. Should help to prevent some of the ugly crashes we've seen in the past.
In the end Alberto gave Andy the stage as a gesture of goodwill. On paper at least, he should be a decent enough time trialer to drive it home safely.
Yeah, it looked like they contended up until the last few meters. Andy came off the handlebars a few meters early, depending on which of those lines were the actual finish line.
I noted a couple of times where, just before the barriers, the leading motorcycles couldn't get through the crowd and the leader had to slow up a bit to avoid running into the back of the MC.
