WHAT IS THIS?
NFC-tagged ultrarunners Petri Perttila and Sakari Haka will 
run from Athens to Sparta to Athens (490km). This test have 
two motives: 1) Test WT's NFC Patrol service on the field, 
and 2) make runner's location available for interested parties. 
No accurate route/gps-data available at the time of writing 
this so distance/speed cannot be calculated and there is no 
predictions about update frequency, but most likely it will 
be 'few hours' at minimum.  This is not official 
timing service.
