We participate in the “limited sled sprint” classes of races sanctioned by the International Sled Dog Racing Association (ISDRA).  Under ISDRA rules a 6-dog sprint team runs a course of at least 6-mile length over two days.  An 8-dog team runs a course of at least 8-mile length.  Points are assigned depending on caliber of competition, purse, course length and days of competition. A musher’s season points are totaled to determine international ranking.  ISDRA maintains a Profile of each member musher that summarizes their career records (see Preston's Profile). Races are conducted by the Sierra Nevada Dog Drivers (SNDD) and local communities such as the Foresthill Chamber of Commerce. A race is a great opportunity to primarily have fun and to judge your team’s speed and obedience to commands.  The fastest team does not necessarily win. A winning team must successfully negotiate turns and make head-on and side-on passes with other teams. Also the musher must remain upright and in total control of the sled! Often control is not an easy thing on “technical” courses in the Sierra Nevada mountains where trails can be steep, twisting and icy. It seems that the harder it is on the musher the more fun it is for the dogs!
