To win your age group at BolderBOULDER is a huge accomplishment. Recording one of the twenty best times in your age for the entire history of BB10K makes you a legend.  The list for each age is linked below.  The most dominant man and woman of all time (and still running) are:

Dave Dooley
Placed in the top twenty all-time of his age 29 times between 1985 and 2015 (including six all-time bests)

Libby James
Placed in the top twenty all-time of her age 27 times between 1983 and 2015 (including nine all-time bests)
