Mound's Jan Guenther has already made her mark at Ironman Wisconsin. In 2002, she was the fastest amateur overall and set a masters record--10:24:42--that still stands. Only one other amateur woman in the history of this race has gone faster. Germany's Isabella Jungfer went 10:19:28 in 2007.
Now 50, Jan will almost certainly set another record at IMWI on Sunday. The 50-54W's mark--Tamsen Schurmen's 11:45:56 set in 2008--is soft. Barring mechanical catastrophe and/or hellacious weather, Guenther should drop this mark by more than one hour.
If all goes well this weekend, Jan may accomplish more than just the rewriting of a single event's AG record. She may approach, or even eclipse, some of the international milestones* established by 50-54 women.
