My race reports from the last four years are in my blog (see link in sig), and I collected links to other people's race reports as well.
They're all tagged Everest Challenge for easy searching.
The race web site has a lot of info, poorly organized. But it's worth looking for and reading it all.
There's at least one set of GPS points out there. I'm not sure they're all that useful- elevation profiles dont' seem to completely capture the difficulty.
