Riding Massive Mountains in Tour de France - Toughest Day Ever!

This video was filmed on the INSTA360 Ace Pro 2 and X5 cameras https://store.insta360.com/product/x5... What's it like to ride the two big mountain stages from the 2025 Tour de France? I found out, the hard way. Join me as I attempt to ride stage 18 and 19 from the Tour as a way to put ENVE's brand new SES 4.5 Pro wheels to the test and joined by fellow YouTuber Ben Delaney. This video is NOT SPONSORED by ENVE. They provided the bike and hotel room but I drove the 12 hours to the Alps in my van and this isn't a review of the wheels, I'll save that for when I get to test the on more familiar roads in the future.
