Fill in any two of pace, finish time, and distance, and this calculator solves the third. It is made for runners planning a race goal or a training run, in kilometers or miles.
• Solve for pace, finish time, or distance from the other two
• Start fast with 5K, 10K, half marathon, and marathon presets
• Get a split table for every kilometer or mile, with an optional negative split
• Predict equivalent finish times at other race distances from one result
• See the matching treadmill speed for any pace
• Save named plans with notes and reload them later
• Build a pace band with a checkpoint every kilometer or mile, every 5 km, or at a custom spacing, then copy or share it
• Get easy, marathon, threshold, interval, and repetition training paces from one recent race (Daniels/Gilbert model)
• Copy or share a clean pace summary before race day
Solve pace, time or distance; get splits, a pace band and training paces
