The best solution in my opinion is using those GPS running stopwatch, they are smart enough to give very accurate run distances and speed as well as terrain inclination and such.
Some of them are equipped with heart monitor and can record efficiently your health performance i e your heart fitness etc.
They are expensive but they are worth, just make sure to buy those with Genuine GPS censor.
Any cellphone or tablet could do the same job if equipped with GP censor.
I have never owed any GPS stopwatch i was just fascinated by them 4 years ago, but my fascination ended when I stopped jogging so I forgot them.

I have the galaxy. I'll try that and then compare it to map my run too! Well after I figure out how to use the galaxy! :o

I do exactly what sailordoom does. Google maps is great for tracking your mileage :)

I missed this part before! Yes the stride was set properly. The pedometer (supposedly) is supposed to accurately convert the steps into miles plus show the cals burned when you had it on timed walk or run.

As far as map my run, love it! I have mapped quite a few of my runs, blading and biking routes over the past few years.

I activated the GPS on my galaxy and tried it out with some of the apps. It is so real time and location accurate it kind of creeps me out. I actually walked around a building and it showed exactly where I was the whole time! :eek:

As far as tracking all of my runs with it I am having the same issue I had with MMR and trying to google it. I get a message or error code that says "location can not be accessed, can not understand location or location unknown" which is why I got the pedometer. :mad:

I think I will just use my slowest pace mile to calculate it. :)
