I wouldn't want to be leading the GC by a couple of seconds and having that final descent in front of me. Skjelmose has had a few disappointments in his career when it comes to top finishes, so I think anything can happen in this TT.
Skjelmose sounded worried about those skinsuits from the organizers when he was interviewed the other day. No idea how much of a difference it really makes, but as van Aert was slower than expected as well, maybe it comes with quite a disadvantage indeed.
