Sounds like you had a great time on the GR20!
Getting from Calenzana to the Refuge d'Ortu di u Piobbo in half a day must have been a serious confidence booster for the rest of the trek.
You did well to include a few extra mountains. I managed your 'Day 8', climbing Monte Ritondu in the morning, then taking the high-level route to the Refuge de l'Onda in the afternoon. It was well worth the effort. I climbed Ritondu with a French Canadian woman, but she took the low-level route to l'Onda, and arrived much later than me.
I'll have to have a read of the blog now.
