Half Marathon Pace Formula:
Where:
P = Pace (min/mile)
T = Time (minutes)
D = Distance (miles, typically 13.1)
| From: | To: |
The half marathon pace is the speed you need to maintain to finish a 13.1-mile race in your target time. This calculator helps treadmill runners determine the exact pace per mile needed to achieve their goal time.
The calculator uses the simple formula:
Where:
Explanation: The formula divides your total target time by the race distance to determine the pace you need to maintain each mile.
Details: Knowing your required pace helps with treadmill training, race strategy, and ensuring you don't start too fast or too slow during your half marathon.
Tips: Enter your target finish time in minutes (e.g., 120 for 2 hours) and the distance (default is 13.1 miles). The calculator will show the required pace per mile in minutes:seconds format.
Q1: How accurate is this for treadmill running?
A: Very accurate, as treadmills maintain consistent pace. However, account for 1-2% grade to simulate outdoor running resistance.
Q2: What's a good half marathon pace for beginners?
A: For first-timers, 10:00-11:00 min/mile is common. More experienced runners might aim for 7:00-9:00 min/mile.
Q3: Should I train at my goal pace?
A: Include some workouts at goal pace, but most training should be at slower, conversational paces with occasional faster intervals.
Q4: How does treadmill pace compare to outdoor running?
A: Treadmill running is generally easier due to no wind resistance and perfect pacing. Add 1-2% incline to better match outdoor effort.
Q5: Can I use this for full marathon training?
A: Yes, simply change the distance to 26.2 miles for marathon pace calculations.
