Iowa Spring Classic, Colfax

April 14, 2019 @ 10:00 am 4:00 pm

Date changed to April 14th…
The course is a mess and I’d rather not have folks ripping off rear derailleurs in the sloppy gooey stuff. Onto a later and hopefully dryer day on the calendar.

ALL pre-registration will carry over to the later date.
