The recorder that is built into the software has the ability to record snail-trails (a series of locations making up a history of your activity), your elevation, speed, heading, GPS accuracy. From the core data, other calculations can be carried out and recorded, such as distance travelled, distance from your planned end point, deviation from your route, time to finish, etc, and a whole host of other calculations that can be recorded. Also, if bluetooth devices are connected, then the data from these devices can also be recorded, such as heart rate, cadence, etc.
