All SNSC athletes will automatically get an RMN (Rocky Mountain Nordic) race license for the season. In addition, all athletes who plan to race MUST get a USSA license.
For U14 athletes the basic license will work.
For U16 and up you must get a competitor license.

When you register with SNSC for races you will need to have your USSA number. It is used to track your results and rank you on the national ranking list. You will not be able to race without having this number.
