Altitude is tough, but I am really happy with how I did in my 1.5 mile run! I did 17:45. Really delighted to be middle of the pack (the two triathletes led the group, and then I was 4th out of the six people).
Other people casually decided to do this course, and did no extra exercise. I am the only obsessive one who has been especially training for months for this day.
Then they fed us sandwiches. I went into super hoarding mode and ate more than anyone else.
Now we are doing gear check and will embark soon.
