Here is an example of how to import drills. I am using the drills I Mailed to myself in the export example.

1. Bring up the Mail app and select the email message with the CMT drills previously exported from CycleTimer2.
2. Tap on the CMT drills attachment. The Share menu pops up.
3. Select the CycleTimer2 app from the pop-up menu.
4. CycleTimer2 will now have all the drills available and they will remain available across restarts.
