Susitna 100 & Little Su 50K
The current 100-mile course has evolved through a history of tradition, opportunism, stubbornness, and confusion. After hosting our races for 14 years, the Big Lake Lodge has closed. We will no longer be able to start and finish the race on Big Lake. Every ultra-distance race course has a cruel joke somewhere; ours has always been the seemingly endless crossing of Big Lake at the end of 100 miles. |
