Type your goal finish time, pick the race and choose mile or kilometer splits. You get a narrow wrist band with the split time and elapsed clock time at every marker, ready to print, cut out and wear on race day.

How to use the Pace Band Generator
Choose the race distance and whether you want a split at every mile or every kilometer.
Enter your goal finish time in hours, minutes and seconds.
Pick a pacing strategy: even pace, or a negative split where the second half is a little faster.
Optional: add hills by listing the net climb or drop for each split (from the course elevation profile).
Download the PDF, print it at 100% scale, cut out a band along the dashed lines and tape it around your wrist or tuck it under clear tape.

Race-day tips for using a pace band
Check the elapsed column as you pass each marker. It is easier to compare your watch with a target clock time than to work out pace in your head.
Course markers vs GPS: GPS watches usually measure a little long because you cannot run the exact shortest line, so your watch may show slightly slower pace than the band. Use the official mile or km markers.
Bank no time early. Going out fast feels easy but usually costs more later; an even or slightly negative split is the classic approach for road races.
Hills: run by effort on climbs and let the time come back on the descents. The hill-adjusted band shows how much time each split may cost or return.
Make it last: cover the band with clear packing tape, or print it on cardstock, so sweat and water stations don't smudge it.
Frequently asked questions
How is the pace calculated?
For even pacing, every split gets the same pace: goal time divided by the race distance. A half marathon in 1:45:00 is 13.1094 miles, so the pace is 8:00.6 per mile, which rounds to 8:01. Split and elapsed times are each rounded to the nearest second, and the elapsed column always finishes exactly on your goal time.
How does the negative split option work?
Instead of switching pace at halfway, the pace changes gradually and evenly from the first split to the last. The ramp is set so that the second half takes the chosen percentage less time than the first half. For example, 2% on a 3:30:00 marathon gives roughly 1:46:04 for the first half and 1:43:56 for the second.
How does the hill adjustment work?
For each split the tool turns your climb or drop into an average grade (height change divided by split length) and slows uphill splits by the uphill factor for each 1% of grade, and speeds downhill splits by the downhill factor. The defaults (3.3% slower and 1.8% faster per 1% grade) are a common rule of thumb, not a precise model, so adjust them to your own experience. The splits are then rescaled so the total still equals your goal.
Where do I find the elevation for each mile?
Most races publish an elevation profile on their website, and route planners and GPS watch apps show the gain and loss per mile or kilometer. Enter the net change for each split in order, using + for climbs and - for drops, in feet or meters.
What size is the pace band?
In the PDF each band is about 1.55 inches (4 cm) wide, and its length adjusts to the number of splits so even a marathon in kilometers fits on one page. Print at 100% or actual size, not fit to page, so the text stays readable.
Why is the last row 13.1 or 26.2?
Race distances are rarely a whole number of miles or kilometers. The band adds a final partial split for the remaining distance, such as 0.11 miles in a half marathon or 0.195 km in a marathon, and its split time is for that short piece only.
Is my data stored or uploaded?
No. The band is calculated and the PDF is created in your browser. Your last settings are kept in local storage so the page remembers them next time.
