How it went

Mark Wooten won the 100 mile in 19:34:20 and now holds the course record, finishing nearly two hours ahead of Charles Linnemeyer, with Becket Duncan third. Sarah Loch-Test won the women's race in 23:49:03 and was seventh overall. Meng Zhao won the 100K and took its record too, and Laura Arnold won the women's 100K; Guirong Wood, second there, was on her way to third in the 100 mile, because 100-milers are credited with a 100K at the end of their sixth loop and can take its awards. Daniel Arnold and Jocelyn Mims won the 50K. 55 runners finished the 100 mile, the last of them in 34:41:51.
