Going to the Sun on a Brompton

I did a thing today. I'm vacationing in Glacier National Park (USA) and took the train here, so I'm using my Brompton to get around. Today I climbed the west side of Going to the Sun Road on it.

It's probably the hardest ride I've ever done. I've had about double the elevation gain in a day before, but never all of it in about fifteen miles.

The Brompton did great, and I'm so glad I put a 40T on the front of my six speed. I used the lowest gear A LOT in the last ten miles.

The descent was a lot of fun, except the cars slowed me down, so I had to use my brakes a lot more than I wanted.
