I purchased the intermediate CX summer sweet spot program. After looking at the program in Training Peaks the ride times during the week are longer than I can do - unfortunately I can only do 1 hour on a weekday.
Should I switch to the basic plan? Is the intensity and the number of riding days the same, with only a change in ride duration?
The basic plans are more or less for true beginners. So along with shorter training time there are less interval work. If you are only able to get an hour of training just cut back the zone 2 time. Focus on completing the intervals. Lots of athletes have this problem, some get up at early to squeeze in a bit more, use a commute to work and etc.
But if you would like to exchange I believe coach @Isaiah can help you out. But I would recommend sticking with intermediate and just cutting the zone 2 time so you get the same amount of intervals.
