I love my gadgets and have been looking for something that i can use while excercising.I run walk and cycle and want something that i can use for all of these to calculate distance,speed and how many steps taken and also want something with gps.There is a fair bit of choice out there and i was wondering what you use/would recommend?I have an iphone 5 and an ipad so i would need to be able to use it with those and im not limited by budget either.
