I thought it had more climbing in 2019 too, but the parts I didn't like were essentially the same. I really don't remember the westbound climb up le roc'h being quite so long. The last stretch before Loudeac on the return seemed a lot different.
All the climbing was harder than 2011, since many of us had a tailwind both ways that time. I was in my big chainring going east up le roc'h, that was fun.
