Intermediate 5k Training Plan
If you can already run 5k but want to run it faster, this 10-week intermediate plan develops the specific fitness - aerobic capacity, lactate threshold, and VO2 max - needed to lower your personal best. It assumes you are already a consistent runner and builds quality sessions on top of a solid easy running base. The approach is structured and evidence-based: you will work hard on the right days and recover properly on the others.
