How many Kenyans do you see cruising around Iten with GPS devices and heart rate monitors? Zero that's how many.
If you have any device more complex than a BASIC 30-LAP TIMEX IRONMAN you might as well be wearing an ipod with big fat headphones. Especially if it's GPS. If you can't figure out where you are and accurately judge the distances you've covered on the basis of your geographical knowledge, you don't even belong outside. You should join a cross fit gym with other pretend athletes if your navigational skills are so impaired.
If you think it's even remotely meaningful for a GPS to tell you your run was precisely 10.1km instead of approximately 10km, then you know nothing of training either and are a hobby jogger.

I have a photo of Kenyan runners on a dirt track with HRMs on. Not sure how to post it here though.
