$70K seems to be a pretty good number. I wonder if it's significantly better than last year?

I was thinking the same thing. I tried finding last years give day #'s but im either clueless or just cant find it. 70K seems pretty great.

The champions achieve initiative they did last year raised 40K which was over the expected..

I suspect that once they tally up the challenge donations it will be twice that amount. One challenge alone was 50k. I believe its based on the number of people joining in on the challenge, not necessarily the amount. So any small donation will help initiate the challenge.
