check out - or one of the many other google map sites on the web.. they all have built in pedometers and if you use the hybrid view, generally if you walk off street - likein a park - park paths do show up
I have had 3 models of pedometers and the best one for me is the one that a friend got for me from Weight Watchers. She had one and recommended it and so I thought that I would give it a go.
I wear it on my waistband above the centre of my right knee. It seems to work best there.
I am quite fussy and am fairly comfortable that it works ok - although I walk such similar walks that I sort it out if a problem arises.
Generally I used the concepts of sanity, consistency and replication to confirm that it works ok.
Sanity
You measure a step length and key it in. It counts the steps and tells you how many miles you have done. You drive the same walk (e.g. 6.3 miles) and check the distance using the tripometer. It makes sense if it all agrees.
Consistency
So you have walked 6.3 miles on day 1. Make a note of start and end stepcount and distance.
Walk it again a few more times and compare the deduced walk stepcount and distance (i.e. end stepcount less start stepcount etc).
You cannot expect it to be identical - but it should be a reasonably similar number.
Replication
This demonstrates my eccentricity - but I admit to it anyway.
Dont feel that I am saying that you should do this.
Anyway I just happen to have a second WW pedometer.
I have been known to clip one above the centre of my left knee and compare deduced walk stepcounts. The last time that I did this there was only a difference of about 40 steps over 6.3 miles which I thought was pretty impressive when you pause to knock stones out of sandals and chat etc.
My husband had to get a pedometer that clips to a pocket. It seems to work ok - the only real flaw is that it is designed for exercise only so it doesnt count the first 4 seconds of any piece of walking activity. My husband doesnt like that aspect because he thinks that if you do the steps you should get the step credit for having done them.
The WW one is no good for him because he has a much bigger tummy than me (he is over 350 pounds). Basically if a roll of tummy (or boob for that matter) hangs over the pedometer it can suppress some of the steps so it gives you a low count. When I first got my pedometer I needed to start wearing a more supportive bra.
I hope if you are doing 3 mile walks that your foot is better. You had problems the other day.
