The Half Marathon Distance Calculator helps runners estimate their total race time based on their pace and the distance they plan to run. A half marathon is typically 13.1 miles (21.1 km).
The calculator uses the basic running formula:
Where:
Explanation: This simple calculation helps runners plan their race strategy by understanding how their pace affects their finish time.
Details: Knowing your expected finish time helps with race preparation, hydration/nutrition planning, and setting realistic goals. It's especially important for first-time half marathoners.
Tips: Enter your average pace in minutes per mile and the distance in miles. For a standard half marathon, enter 13.1 miles. The calculator will output your estimated finish time in HH:MM:SS format.
Q1: What's the average half marathon time?
A: For recreational runners, average finish times range from 1:50 to 2:30. Elite runners complete it in under 1:10.
Q2: How do I convert km to miles?
A: 1 kilometer ≈ 0.621371 miles. A half marathon is 21.1 km or 13.1 miles.
Q3: Should I use my training pace?
A: Use your goal race pace, which might be slightly faster than training pace due to race-day adrenaline.
Q4: How accurate is this calculator?
A: It provides a basic estimate but doesn't account for hills, weather, or fatigue. Actual times may vary.
Q5: What if I want to calculate pace from time?
A: Rearrange the formula: Pace = Time / Distance. Enter your target time and distance to find required pace.
