I'm attempting to expand the Indiana HS Alum records I maintain here
(for men) and here
to include the Olympic distance walks. I believe I correctly have the best for the men's 20K and 50K:
20000 Walk - 1:22:31 - John Nunn (Evansville Harrison HS '96) - US Army - Birstonas, LTU '04
50000 Walk - 4:03:28 - John Nunn (Evansville Harrison HS '96) - US Army - London Olympics, ENG '12
However, the best I found on the women's side is the following and I'm not sure if it's even the fastest by Sonntag or whether another alum has walked faster.
20000 Walk - 1:46:23 - Lisa Sonntag (Crown Point HS '82) - Unattached - National Invitational, VA '00
So the question for the walk experts is does anybody know if Sonntag or another Indiana HS alum has walked faster?
