Next Week’s Mileage (NM):

The 10 percent rule running calculator is a handy tool for runners to gradually increase their weekly mileage. Adopting this rule helps prevent overtraining and injuries by ensuring a safe progression in training loads. This guide will explain the formula behind the calculator, how to use it, and provide an example for better understanding.

Formula

The formula used in the 10 percent rule running calculator is:
NM = WM + (WM × 0.10)
Where:

• NM = Next Week's Mileage
• WM = Current Weekly Mileage

How to Use

1. Enter your current weekly mileage (WM) into the calculator.
2. Click the "Calculate" button.
3. The result will display your recommended mileage for the next week (NM).

This ensures you adhere to the 10 percent rule for a safe and structured mileage increase.

Example

Suppose your current weekly mileage is 30 miles. According to the formula:
NM = 30 + (30 × 0.10)
NM = 30 + 3 = 33
Thus, your next week’s mileage should be 33 miles.
