I don't think I will ever spin higher than the mid-eighties for any distance. Being about 6'3" and over 200 pounds might have something to do with it, also have chronic cardiac problems I can't antagonize that are getting worse with age. Hopefully I will be able to at least hold my current fitness level this year fingers-crossed.
