Undefeated on Work Naked Day

Kara posted that she was undefeated racing on Mother’s day.  I thought that was pretty cool and of course it got me thinking “am I undefeated on any days”?
 
I’ve raced on nearly every day of the year, having only seven dates that I’ve never raced on (Feb. 29, April 4 & 13, Aug 11, Nov 19, and Dec 18 & 24).  I ended up finding 12 days that I’m undefeated on, but 9 of those are days I only raced on once.
 
Multi-win undefeated days:
02/05 which is “shower with a friend” and “Work naked day” – 1981 2m versus Central 1^st place 9:41.6, 1983 tri-meet versus Colby/Bowdoin 2m 1^st place in 9:11, and 1995 Freeze your buns 5m 1^st place in 26:45.
 
02/23 which is “National dog biscuit day” – 1991 Twosome 3.6 mile race won in 18:11, and 1992 DH Jones 10m won in 50:36.
 
09/27 which is National chocolate milk day – 1987 Marshfield 20k won in 63:10, and 1992 Fallon 5m won in 24:25
