why all this technology? It complicates running. I don't time my runs, but I check the time before I leave the house and when I return. I have a rough idea how far I have run based on my usual pace. I know I can run 1.5 miles in under 9 mins, I know I can run 5k(20mins) 10k(40mins) so if I am back home and 70 mins have gone by -10 mins warm up, I have ran 8-9 miles, but we we always sprint with everything left so it could be 10, yes I could be a mile or two out, does it matter? Well as i'm not in the 2012 olympics, no. Running is fun, when you make it into a job like activity checking progress and if your reaching targets then what are you trying to achieve? Maybe I just don't get it.
