Junk miles aren’t easy, they’re in zone 3. Sometimes called “comfortably uncomfortable”. Too hard to be low impact and facilitate doing harder runs later at full intensity, but too easy to get the benefits of doing a really hard session. Elite runners polarise training to 80% zones 1–2 and 20% zones 4–5.
