Hee, we are only pretending to be hard core! But speaking of, check out The Kepler Challenge (http://www.keplerchallenge.co.nz/) - this is a 60km trail ultra on the trail we hiked here (http://www.flickr.com/photos/svwindom/sets/72157613958796960/) (and when I can upload again, I have lots more for that set). We did it in four days; the record is a little more than four and a half HOURS.
