I'm only the 2nd woman who has signed up. I'm sure there will be more closer to the event, but for now it's just me and one other. The RD messaged me and said he wanted to do a full 10K, but that there was no interest in that distance in Oklahoma. I told him I would TOTALLY do that distance if it were offered. I'm sure there are at least a few other endurance junkies who would join me.
