Going up to the Grimselpass and later to the Furkapass, Switzerland, was easy. I took busses. Furkapass lies 2436 meters above sea level. There were plenty of magnificent views all day long. Going down was a challenge, though. I had to stop every kilometer for a couple of minutes to let my rims cool down. The Brompton brakes were at their limits in terms of heat dissipation. I am now in Andermatt.
