So here's some random trivia about Peter Nickles. DC knows him as Fenty's general counsel and now the Acting Attorney General after Linda Singer resigned. He has a bit of controversy surrounding him since he is the reason why Linda Singer resigned and he apparently isn't a DC resident either although it's a job requirement.
Well, I just read in the March 2008 issue of DC North that he is an ultratriathlon competitor. An ultratriathlon consists of a 6.2 mile ocean swim followed by a 261.4 mile bike ride and ends with a 52.4 mile run! In the article ("Help Wanted...Experience Necessary" by Mark Segraves on page 22), it says he completed the Ultraman World Championship Triathlon in Hawaii twice, at the age of 63 and then at the age of 67!
Although it is a bit of useless trivia, it probably is a good insight as to his personality or perhaps his work ethic. My in-laws have competed in triathlons and I know one other person who has completed an Ironman. The amount of training and commitment needed to do the Ironman is pretty intense so the training involved with an ultratriathlon must be insane! And he did this in his 60s!
