Running tools, without the mental maths.

Calculate a pace, compare targets, check every split and prepare a readable printout.

Running Pace Calculator

Calculate pace, finish time or distance with clear kilometre and mile results. Start with a 10 km, 50-minute example.

Build a cumulative split table from your distance and target time, with kilometre, mile, track and custom markers.

Create a printable marathon or half-marathon pace band with your target time and splits. Download PDF or SVG for A4 or Letter paper.

Convert treadmill mph or km/h to minutes per mile and kilometre. Check speeds such as 6 mph, or find the speed for 5:00/km.

Find how many 200 m or 400 m laps make your distance, including a partial lap. Calculate lap times for 5K, one mile or a custom distance.

Allocate your chosen total time between equal distance halves and check both half times and paces.

Compare two to four finish-time targets for the same distance, with clear pace units and CSV export.

Create a compact pace-to-finish-time grid for selected distances, with explicit pace units and CSV export.
