Review of Run App

@ber ok I think for this we really need some data.

• Please could you use the latest Run from the development app loader, with the recorder set to record every second?
  
• Then record a walk/run (even around a small area) and tell us the distance you get from the Run app, upload the GPS trace, and the distance you get from analysing the GPS trace.
  
  

If you set the GPS recorder to update every 3 seconds, that will be skipping out 2 out of 3 GPS readings, and I'd expect that to then show you a lower trek distance when you analyse it than the Bangle would find when it looks at every reading.
