Race Pace Band Printer

A pace wristband (or pace band) is a small printed strip worn on your wrist that lists the elapsed time you should reach at each kilometre or mile marker to hit your goal finish time. It lets you check your pacing at a glance without doing maths mid-race. The generator works for the marathon (42.195 km), half marathon (21.0975 km), 10K and 5K.

Enter your goal marathon time, choose kilometre or mile splits and an even or negative split strategy, then press Print. Cut out the band, cover it with clear tape to waterproof it, and tape it around your wrist.

Even pacing is the most efficient way to run a marathon for most runners. A slight negative split — running the second half 1–2% faster than the first — helps avoid going out too fast and is how most world records are set.

Use both. GPS watches drift in cities and tunnels, often reading 0.5–1% long by the finish. A pace band keyed to the official course markers tells you exactly where you stand against your goal.

Cover both sides with clear packing tape or laminate it. This protects it from sweat, rain and water stations.
