RunCalc works with GPS in your phone (presentation model: Nokia 500) or with an external module (via Bluetooth). I recommend running with armband.

GPS settings let you configure many options before your run. You have 6 screens to monitor your training: distance, pace, altitude, laps, course map, Google Maps (4 map types, zoom in, zoom out), elevation chart.

After finishing your run you can view training data on your phone.

You can send your training to RunCalc portal where you can easily analyse and modify data.

Training can be visible immediately on Facebook timeline.

Using RunCalc GPS is free. It's good to use Internet on your phone which allows to: catch GPS signal quickly (AGPS), download map in case of navigation problems, send training data to RunCalc portal. All the operations require very little data transfer, so package 100 MB per month should be enough.
