It has been several years since I have done a WORS race. In the late 90's, early 2000's they were very popular. I raced in the 40-45 Citizen Class and most of those races had 40-50 riders in just that age group/class They were quite competitive. I was fortunate enough to finish in the top 5 a few times.
They were very well organized. Several of the races were held at ski resorts and had their share of climbing. The Citizen races did not have a lot of technical aspects to them. The starts can be pretty crazy, so be prepared for that.
