I have been trying to figure out how far I've run by manually measuring it with the website: onthegomap.com/#/create which gave me a good enough idea for shorter distances. But now that I am on the Week 9 running 30mins continuously, I found myself losing track of how many loops of the park I've done. Also, I just did W9R1 this morning and OnTheGoMap says I ran 5.55km, which seems impossible to me as I could only run 4.4km in 28mins last week!
I'm finally going to give phone GPS tracking apps a go. I downloaded Under Armour's Map My Run and don't like the way it collects so much of my personal data. Apart from that, is there one you would recommend?
