Its fun to see this mentioned here! Thanks for posting, Nathan. I must agree with Duane. There is no issue here.
I've been a member of this club on and off for years. It is a private club and as such I consider their private rule regarding what they will accept toward their recognition of marathon "credit" to be very well written from our perspective. When active as 50 State club runners, we all travel around the country and run many marathons for the heck of it.
The club encourages races to certify their courses. But the main idea of the club is to encourage runners to run a marathon in all 50 states. Frequently, there have been states that had no marathon or ultra offered at all or no marathon over a certified course. Allowing the trail course and or the not-yet-certified course enables the members to continue to pursue their objective.
I believe the organization has a positive effect: they often bring many runners to remote events, the RD's know this, like it, and listen to the club's advice regarding the importance of course certification. But, they don't stop running in a state unless that state momentarily has no marathon or ultra race at all -- which happens from time to time.
