I am loving the plan so far, however I was hoping to get some clarification about the prescribed weekend workouts on the SS2 plan. Sometimes I don’t have a group to ride with or prefer to do a structured trainer ride. What are some targets I should shoot for as far as time spent in the SS for one of these longer weekend SS rides if I am solo or if I do it indoors? Details such as IF targets and interval lengths would be helpful. Thank you for the clarification.
