Geoff Roes is one of the best ultra trail runners to participate in this sport.  He has won many races and set course record on many of the most difficult 100-mile races in the United States including:

Susitna 100 CR
Resurrection Pass 100 CR
2-time winner: Wasatch Front 100
Hurt 100 CR
The Bear 100
Western States 100 CR
Santa Barbara 100 CR by over 3-1/2 hours!

He was captured in the JB Benna film, Unbreakable, when he pulled off one of the greatest athletic come backs of all time!
Geoff elaborates on his recent article he wrote in Ultrarunning Magazine.  He began having severe symptoms affecting nearly every system of his body and how he has tirelessly struggled to understand the cause and remedy.  Although still not sure why or how this came upon him, he has come to peace with the joy of running and taking each day by day.
