Flatlander Ultrarunners in Chicagoland

Flatlander Ultrarunners in Chicagoland is a running group based in the Chicago area, which includes "Flatlanders" from all over the Midwest and beyond. The group consists of ultra and trail runners, as well as those aspiring to try ultra and trail running. The group has no dues or fees and is not a for-profit venture. There is no owner or leader - this group exists by and through its members. The only requirement to be a Flatlander is a commitment to crew or pace another member, and to volunteer at one ultra per year.
