Just checking. You were asking about next CJ plan so I was not sure. Outdoor takes real dedication to try to do quality intervals. You can use it with a Garmin or Wahoo bike computer. I am not in love with that experience but it is popular. I personally suggest using the “top tube” approach like many pros do, which is just write down your main intervals on paper or in message format and do your best to follow them. So the plan is more on paper. Hill repeats are good for say 10-30 minutes of your ride. Really with CJ plans only the main work needs paying attention to not the secondary (just stay in approximate zone).
So in your case after #18 threshold progression you could do #7 threshold blocks. You are just trying to do 3 intervals at 4 minutes each of threshold. This might be 3 hill repeats.
