Hi guys just a quick question here. I was out running around the park before and went at a pretty fast pace. Well what i now would consider to be a fast pace as it is only my 3rd week of training. I was aiming for a 1.5 miler and because i ran 2.5 miles pretty comfortably the other day i thought running at a pretty fast pace would be simple. But with about just over half the run left i was breathing like crazy and i just had to stop. So the question i have is do you know of anywhere there is were i can get some sort of equipment to measure how far i am running since i'm not really sure how far i actually ran.
