If you haven’t registered for one of the 2013 Black Hills 100 events yet, you only have until April 1st to take advantage of our early bird rates. After that, registration for each event bumps up $25, so get over to Ultrasignup now and save a few bucks. Remember, we have entry limits this year and the 100 mile race is currently at 2/3 capacity. If we get our typical rush of entries just before the early bird deadline, we could be near capacity for the 100 mile. Your best bet is to register now and secure your spot!
