If you use the Marware Nike+ Pouch . . .

. . . make sure the sensor is in the right way. A few years ago, I started using the sensor with velcro strapped to my shoe.  It worked great.  I even wrote about it. This week I got a new

pair of running shoes and started using a Marware pouch.  I found that my three mile runs were being logged as two miles.  I was gutted and the pouch was on  its way to the bin. Then I read the instructions more carefully.  I had put the sensor in upside down. Now I'm back from a run and want to post this before I forget.  If you found this post because you are googling Marware pouch problems, I hope you find this tip useful.
