Multiday race or Multiple races?

I briefly read this article yesterday and mention of a multi-day race that I hadn't heard of before, a Trans-Himalayan race, caught my eye. I followed the link at the end of the article but it seemed like a mistake as the site the link took me to didn't have any race data. I was a bit disappointed when I looked at the article again today and found that the blurb about the race was removed. Nevertheless, a quick search on google lead me to the race site. I also found this site that has some info on the stages from a previous race. Although it sounds like fun to be racing on "top" of the world, I don't think I'll be signing up for this race next year, if there is one.

Hopefully this wasn't the entire field.

Maybe I could trade one Trans race, say the Transalps, for the new 100 mile endurance series that was also mentioned in the same cyclingnews.com article. The cost would probably end up being about the same as would the required time off. What to do? What to do?
