There were some poor surfaces - I recall being a bit bone-shaken on one section of road on the first night. It was generally very good and nicer than what I've been used to in the uk recently.
I'm on a Domane SL, with Isoflex front and rear, Isocore (elastomer inserts and padded) bars, Enve SES ARD wheels (Asphalt/Gravel) with 28mm tubeless tyres (come up around 29.5mm on these rims) at 55psi. I think I'll be fairly comfortable, as these things go. More so than the previous three rides on VN Yukon with Open Pro wheels and 25mm tyres.
I'm planning no mudguards, just like last time.
