4. Click the "Select Athletes" and pick the athletes who will be training for the day

6. Tap on an athlete and tap the "Assign Sensor" button. 
   
   
   
7. Tap a sensor from the list to assign it to an athlete.

   > If you are looking for para factored times, you will need to select the specific alpine discipline for the day.
   > It is possible to start a session at any time, before, during or after a training session.
   
   
   
   
9. To sync an in-range sensor with the cloud, tap on a name and tap "Sync Data". Alternatively you can sync all sensors in range by tapping "Sync All In Range".
   > Note the closer the phone is to the sensor, the faster the sync
   > The athletes need to stay in range of the phone while a sync is happening in order to not loose data
   
        
   
   
10. At the end of a training session, tap on an athlete and tap "Sync & Stop". Alternatively you can sync and stop all in-range sensors by tapping the red button labelled "Sync & Stop". This will sync all the data and turn off the sensors.
