Good luck to John (and everyone else) running the Hardrock Hundred this weekend. You guys are impressive. I will do a paltry 22 mile run tomorrow in your honor, and I will try to keep my bitching about the heat to a minimum in light of the distance, altitude, and terrain you will be traversing this weekend.
For those of you who aren't aware (and I certainly was not until recently), Hardrock is a 100 mile run with 33,000 feet of climb, mostly at 10,000 to 13,000 feet elevation. The highest point is 14,048 feet. Holy crapola.
Here are some pics I found on the web. These are actual shots of folks running Hardrock. Let me say it again: HOLY CRAPOLA.
Vaya con Dios, amigos.
