We recently updated the race packet for 2012 (and consolidated the three separate packets for the three distances into one). You can find it here: http://www.blackhills100.com/course_info/race-packets/
Also, if you haven’t registered already, remember that the VERY LAST DAY to do so is June 10th. It’s a bit of a logistical mess for us to accept registrations any later than that, so if you know you want to run, get over to Ultrasignup and get registered by then (the sooner the better!).
As a reminder, we do not offer refunds, but we would be more than happy to roll your registration fee over to next year if something comes up that prevents you from running this year. Just send us an email at firstname.lastname@example.org and let us know.
