If your younger runners have a smaller track distance you can assign their teacher a custom lap distance.
In this example we will add a .10 mile lap distance to a kindergarten class.
1. Click Settings in the sidebar menu.
2. Under Lap Settings add ".100" to the Custom Lap field
3. Click the Save button.
Click Teachers in the side bar menu and then Edit
1. Change the Custom Lap to "0.100"
2. Click the Save button
Now every student in this class will use the lap distance of "0.100" with each scan.
Change the distance to '0' and click the "Update" button.
This deletes the custom lap distance and restores the "default" distance to any teacher it was assigned to.
