Allie Chipman won't be back to defend her course record from 2015. Mountain Vista busses are pointed toward Liberty Bell this year.
The current course configuration at the St. Vrain Invitational dates back to 2013, just before the massive flooding hit Boulder County. A lot of very strong efforts have been laid down on the course since that time, but only Chipman has been able to dip below 18 minutes.
Can somebody else do that on Saturday? You'll have to show up and find out. In the meanwhile, though, if you're hoping for a place on this list, it's going to take at least a 19:23.
