Increase that long ride 10% per week. In 2 months you should be at that 60-70 mile level. Intensity is not well tolerated by us older riders but paradoxically is most needed. So, you also need about an hour total in a week riding hard.
I’d agree about needing one longer ride each week if you want to do those long club rides. Also, I agree about a total of one hour per week riding hard, as in 90% of maximum heart rate, if one can tolerate it.
