I'm sorry to say I didn't even know Diane Goulett was not well until I read this obituary.
Minneapolis Star Tribune
I remember her from some of the earliest Race for the Cure (Twin Cities) races. When I did a quick search of race results for her, I saw that she ran that race in 2003.
The obituary says she stopped running in 2003. RFTC could have been one of her final races.
