Threw my name in the hat for WS100, we'll see what it brings.
Rooting for Alex and Brandon to get in as well.
Popular race, of course. I remember being enthralled reading about it in "Karno's" book 5 years ago, after meeting him at a book talk. We can all joke about that, but I'll admit still that some of that really got me intrigued about ultramarathons (keeping in mind I had barely done a few half marathons at that point), precisely and ironically because of the lack of glamour of the whole thing when he talked about training and running at night, etc.
Anyway, this race and Hardrock are the two I'd most like to do, and (lacking a HR qualifier) it would be most convenient to do them in that order!
