1. What is Running Speed Comparison By Age?

Definition: This calculator compares running speed adjusted for age, accounting for typical performance changes over time.

Purpose: Helps runners understand their performance relative to age norms and track changes over time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Speed (mph)
• \( D \) — Distance (miles)
• \( T \) — Time (hours)

Age Adjustment: The calculator applies an age factor based on typical performance decline of 0.7% per year after age 30.

3. Importance of Age-Adjusted Speed

Details: Age-adjusted comparisons help athletes set realistic goals and understand their performance in context of biological changes.

4. Using the Calculator

Tips: Enter your running distance in miles, time in hours (e.g., 1.5 for 1 hour 30 minutes), and your current age. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the age adjustment?
A: This uses a general guideline (0.7% decline/year after 30). Individual results may vary based on training and genetics.

Q2: Should I use miles or kilometers?
A: The calculator uses miles by default. Convert km to miles (1 km = 0.621371 miles) if needed.

Q3: Does this account for training differences?
A: No, this is a basic physiological model. Well-trained athletes may decline slower than the average.

Q4: Why use age 30 as the baseline?
A: Most athletes peak in their late 20s to early 30s before gradual decline begins.

Q5: Can I compare to others my age?
A: For competitive comparisons, use age-graded calculators from running organizations.
