Intermediate 10k Training Plan
A 10k personal best requires you to run at a pace that is uncomfortably sustainable - just below your aerobic ceiling - for approximately 40 to 60 minutes. Achieving that demands specific fitness that casual running does not build. This 12-week intermediate plan develops lactate threshold, VO2 max, and race-specific endurance in a structured, manageable weekly framework that will leave you ready to race rather than just to finish.

Sessions sync automatically to Garmin, Wahoo, Apple Watch, and most other GPS devices via the TrainingPeaks app. You train to the targets on your device - no need to memorise sessions or carry notes.

The plan starts from the date you choose at setup. If you have a specific race date, set that in TrainingPeaks and the plan will align automatically.
