How to use this calculator

  • Enter your goal pace per mile or km.
  • Enter the race distance.
  • Read the predicted finish time.

About this calculator

Pace × distance = time. The trick is matching units — if your pace is in min/mile and your distance is in km, convert one before multiplying. This calculator does it for you and shows the result formatted as h:mm:ss for races over an hour.

Frequently asked

Can I plan negative splits with this?+
Compute the finish time at your target average pace, then pace the first half slightly slower. A common negative-split strategy is +5 to +10 sec/km on the first half.
How accurate are these predictions on race day?+
Very — assuming you actually hold the pace. Most over- or under-estimates come from runners going out too hard early.
Does wind/elevation matter?+
Yes — flat windless conditions match the prediction. Hilly courses or strong wind can add 30-90 seconds per km.
How do I match pace on race day?+
GPS watches will alert at every km/mile split. Many use vibration alerts at fixed intervals.
What is a marathon pace band?+
A printed list of every-mile target times for your goal finish. Wear it on your wrist; check at each mile mark.
