I am home and reasonably sound. The ride was 52 miles and I did a slow grind of it over 5 hours. The last hour especially was brutal. "Scorching" was the word I heard a lot.
My knees are sore and my face remains hot to the touch and I continue to drink water and yet still be thirsty. These are all things that will pass soon enough.
I will post a more detailed account later in the week but wanted to quickly say thanks!
