Dang, that's a lot of up miles. Can you do it on the bike instead? It may be easier. Coming down is just as bad or worst going up for your knee, foot or body. Just knowing myself and my body, I will for sure get a lighter mid weight boot for some much needed support.
Hey, I just noticed your cars. They are similar to mine. An 88 930 with about 460 at the wheels on pump gas and a 2009 Cayman S with some suspension mods. Not to mention the bike. Great minds think alike
