I might be late to the gate with this one but I have just come across an Website called smash run and it is right up my street. As most of you know I'm a Stats girl and boy does this give out in abundance. I have linked it in to my Garmin stats and every run now it give me little bits of extra information and it's for free.
My Saturday run it tells me it was the fastest run of that distance ever, it's told me it's the longest run I Have done for three months and the earliest in the day I have gone out apart from races, all from syncing with my Garmin results.
Here is the link if anyone else wants to have a go. It uses other information as well I think if you have other watches.
