Early bird registration rates for the Tatanka mountain bike race, the amazing, epic race hosted out of Sturgis are ending soon! The registration fees for the epic distance, which is a 135km race starting at Mount Rushmore are currently $150, but will be increasing to the full rate of $200 soon. If you plan to ride your mountain bike in this event, or know of someone else who does, now is a great time to register and take advantage of a lower rate. The registration fees for the shorter 55km distance will be increasing as well.
