Saw this in a CRN posting.
Unfortunately, two problems with this: one it doesn't support the phones we currently use, two; rather expensive at about $10/month (US dollars). Compared to a watch or other GPS device, you purchase it and in some number of months, you have recovered your expense with the service it provides. Here, $10/month on going.
I have a separate user experience problem with their web site. It advertises a "free" online training log. Yes, it is free if you are a paid subscriber. I don't know about you but for me, if you have to pay to get something, then the something else they give you is not FREE.
But if you carry a phone with you on your run, this may be a consideration.
