Good post, agree 100%. Also, a big XC fan and unfortunately, the US XC season does not align with the global XC season, so it is difficult to get commitment from the pros. I do think if someone is doing a spring marathon, XC is a great race to measure one's fitness.
Kudos to Kelati for running this race. Although she can be 'rewarded' with a trip to Serbia, going to Richmond is probably on her own dime, no? (Or perhaps her sponsor's). Still, happy she is doing it. Hopefully, this helps her make the Olympic 10,000m team.
Regarding the European nations not sending full teams, WA needs to tie participation in the World XC with something tangible, although not sure what. Maybe a country needs to send full teams to the XC champs for 5 years straight years in order to be considered to ability to host a championship? Or they get points toward something, etc.
