FKT: Krissy Moehl, Devon Crosby-Helms - Grand Canyon Crossings (AZ) - 2011-04-19
As far as we can tell, prior to 2011 the fastest R2R2R time by a woman was Emily Baer's 9h25m in 2003 or so. However, 2011 was a banner year for women's speed records on the R2R2R. On April 19, Krissy Moehl and Devon Crosby-Helms ran the route in 9h12m. Unfortunately, we no longer find their blog posts about the run.
