I don't think it's a matter of eating crow or settling an argument one way or another. He has spent a few years doing very little in this raceAll those armchair experts who like to complain that vdP doesn't do enough at the Tour must be full by now from all the crow they've been eating this year.
2021: Just as electric as this season, with a planned early departure for Olympics
2022: Ill advised Giro-Tour double attempt coming off of an injury winter. Ended predictably badly.
2023: Made little impression aside from leadouts. Word from the peloton was that he was doing intervals in the gruppetto as part of his prep for Worlds. Whatever he was doing it did work in the end.
2024: Similar to 2023, but the Worlds course was too hard for whatever he did or didn't do in the Tour to pay off.
One does also have to admit that the stages in the first part of this Tour can not have been much more favorable to a rider like Mathieu.
As is probably obvious, I'm a big fan. Glad to see him enjoying himself out there.
