A microcycle is the short repeating pattern of training, usually one week. For most amateur endurance athletes, two quality sessions plus a long session is a solid structure.
Separate hard sessions by at least one easy day; 48 hours between intense sessions is a common rule
Treat the long run or long ride as a third key session, not as an easy day
Put strength work on hard days or on the day after, so easy days stay truly easy
Plan the week around your fixed commitments; a perfect template you cannot follow is worse than a simple one you can
A sample week for a runner with five sessions: Monday rest, Tuesday intervals, Wednesday easy, Thursday tempo, Friday rest or easy, Saturday easy with strides, Sunday long run. Strength fits after Tuesday or Thursday.
