Competitive group ride every Sunday until I croak. October through December, weekdays are on the rollers: base miles, pedaling drills, and tempo intervals (Z3). From Dec. 1 to May, add a Saturday ride but take it easier. Gradually increase length of Saturday and Sunday rides from ~40 miles in October/November to 60+ miles in the spring and keep increasing the climbing with the miles. Keep the weekday roller pedaling drills, gradually add outdoor weekday endurance rides.
October/November mostly upper body weights, hypertrophy. December-February whole body weights going from hypertrophy to endurance. March-May high rep endurance weights.
I don't do any formal program, HIIT, time-crunched, etc. BTW, now is not the season for hitting the intensity. Intensity is the quickest adaptation. Endurance is the slowest. That said, I try to get at least an hour/week of subthreshold/LT work year 'round.
