(From Pem at Deep Language). I hope to look anywhere near as good when I'm 81!
Update: Her name is Mirjam Tuovila, from Yorktown, Vermont, and the photo was taken at the 2006 Greenville (SC) Triathlon, where she was the only female competitor over age 64. She went 11:49 for the 400m swim, 1:02:38 for the 15-mile bike, and 46:09 for the 3-mile run to finish in 2:08:07.
Correction! There must be a typo in the results, and her home must be Yorktown, Virginia, which makes more sense. There isn't a Yorktown, Vermont. Thanks to sharp-eyed Triathlonmom.
