At the eleventh hour I spotted that Kajsa had come down this way yesterday. I successfully predicted which route she would take, and so was able to join her for most of the ride. A great privilege, it goes without saying.
I actually found her quite subdued; perhaps that is in comparison with how she was near the start of the challenge. There's no doubt she's finding it extremely hard, and expressions of support can be priceless. I hope I helped today.
A few times I said things where the reply was "you try it when you've...". I was suitably humbled. That's the feeling I take from this encounter more than any other - humbled.
Go Kajsa!
