Gee, you are a cat2 and you are asking us??
As the saying goes, is not how much time you train but what you do with those time that matters. This year off season I train a lot less than my last one. 3 days and maybe 4 days the most. Last year off season I was pretty much commuting 4 days a week and adding one or two days doing long distance ride. This year I ride less but with greater focus on intensity and duration. 10 hours the most and on average about 9 hours. About 150+ miles a week.
