How the Running Plan Generator works
The plan builds weekly mileage using the 10% rule - mileage increases by no more than 10% per week - with a cutback week every 4th week to allow recovery. The final 3 weeks taper to arrive at race day fresh. Long runs, tempo sessions and easy runs are distributed across your chosen training days.

Frequently asked questions
How many weeks should my training plan be?
For a 5K: 6–12 weeks. 10K: 8–16 weeks. Half marathon: 10–20 weeks. Marathon: 14–24 weeks. If you have more time, start the plan with easier mileage. If you have less, prioritise the weeks closest to race day.
What is a cutback week?
A cutback week reduces mileage by around 30% to allow your body to absorb the training load. They typically fall every 4th week. Skipping cutback weeks is one of the most common causes of overuse injury in runners.
What is a taper?
A taper is the final 2–3 weeks before a race where mileage is reduced significantly. This lets your body repair, top up glycogen stores, and arrive at the start line fresh. Tapering properly is as important as the training itself.
How do I know if my easy runs are slow enough?
Easy runs should be conversational - you should be able to speak full sentences without gasping. Most runners run their easy runs too fast. Use the Training Paces Calculator to find your correct zones.
