I've started seeing a lot of Christmas themed blogger challenges and, even scarier, a lot of 2011 challenges - I can see myself getting carried away with that before long!
The 101 Fantasy Challenge is hosted here on it's very own blog and is run by Michelle from over at The True Book Addict. When I joined up, the idea was to pick a number of books from the list of the top 101 fantasy books, as voted for by bloggers, to read before the end of this year. After some deliberation and input from those who'd joined up to the challenge, Michelle decided to make the challenge perpetual, i.e. read through the list at your own pace.
So if I read through the ones I own but have yet to read, I'm almost half way there :) I'll be keeping track of my progress on my Challenges pages, which you can get to by clicking up at the top.
