The code to process data and plot the chatjs graphs can be found in this python notebook.
A marathon needs to be prepared for at least 3 months. This post shows my preparation training and a prediction of my time for the Metz Marathon 2017
Microcontrollers are adapted for simple task which don't need a lot of battery power. This post shows how to put in actions the Arduino MKR Fox for capturing temperature measurements, send them to Sigfox Cloud and expose the results in a serverless dashboard.
