Make a Race Card with Kilometre and Mile Markers
Make a marathon race card with kilometre and mile checkpoints, halfway and finish. Follow a four-hour example with clearly labelled cumulative times.
Choose one distance and one target
A race reference can become confusing when the route uses kilometres and a watch uses miles. The two sets of numbers are both useful, but only if they come from the same plan. Start with the full distance, one finish target and a stated pacing allocation. Then create the marker sequences from those values, rather than trying to reconcile two independently rounded pace labels.
This example uses a marathon distance of 42.195 km, a 4:00:00 finish and an even pace. The displayed paces are 5:41/km and 9:09/mi. These are convenient labels for one precise plan. They are not new inputs to be multiplied repeatedly to build the card.
Compare the two marker sequences
Kilometre and mile markers refer to different points on the course. The 5 km row appears before the 5 mile row because five miles is 8.04672 km. A two-column card can place their labels alongside each other for reading, but that layout must not suggest that the paired rows identify the same location.
| 5 km | 0:28:26 |
|---|---|
| 10 km | 0:56:53 |
| 20 km | 1:53:45 |
| 40 km | 3:47:31 |
| 5 mi | 0:45:46 |
|---|---|
| 10 mi | 1:31:32 |
| 20 mi | 3:03:05 |
| 25 mi | 3:48:51 |
Keep km and mi visible in the column headings or beside every marker. If you copy only a number such as 10 onto a small card, you remove the information needed to interpret its time. Use a clear title such as “Marathon · 4:00:00” and retain the total distance somewhere on the reference.
Keep halfway and finish once
The exact halfway distance is 21.0975 km. With this even allocation, the halfway time is 2:00:00. The finish is 42.195 km at exactly 4:00:00. Those common anchors do not need to be repeated as if they were separate kilometre and mile targets.
The split calculator removes duplicate distances when an extra marker already falls on the regular interval. That matters for distances such as 10 km, where the 5 km row can also be halfway. For the marathon example, halfway sits between the regular 20 km and 25 km markers and needs its own labelled row.
Prepare a readable card or band
- Create the kilometre table from the selected distance and target.
- Create the mile table from the same unchanged plan.
- Keep selected checkpoints, clear unit headings, halfway and finish.
- Use the pace-band maker for a supported printable strip, or copy the tables into your own static card.
- Check the finish target after any layout change.
The custom two-column example on this page is a reference-card layout. The maker’s band layout follows its selected marker controls and may split a dense list across several strips. Read each strip’s range label instead of assuming that a small preview contains every marker.
For a printed band, match A4 or Letter in the file and print dialog, use Actual size or 100%, and measure the 100 mm calibration line. A larger screenshot on a monitor does not establish the size of the paper output. Choose a readable layout rather than reducing text until the units disappear.
