I am using my Nike + sensor in a pair of Nike Pegasus+ trainers that I have just bought with a nano 7th Gen.
I tried to calculate the distance of my daily run using a few map sites and they all say 4.41 to 4.47 miles. The first run with nike plus said 3.84 the second said 4.04 (I had not calibrated it).
Anyway, I looked at a 1/2 mile route using map my run and then tried to calibrate the sensor. I ran the route until the voiceover told me that calibration was complete and it appeared as if I had run over 50 yards more than suggested by the end point on the map. On a plus, the trainers are very comfy.....
Does anyone have any ideas? What do I believe, the map or the nike+???
Agree with cougie. I found Nike+ very inaccurate and upgraded to garmin as soon as I could. Believe the map!
The problem with Nike+ is that it relies on the shoepod to be accurately calibrated more or less before each run. This is a major problem especially if you complete different types of workouts at different speeds, so your feet may strike the ground more or less often, affecting the outcome.
I ran a half marathon a few years ago with Nike+ and it thought I'd run an extra mile despite me keeping a very good racing line to avoid increasing the distance.
Nike+ does not require calibration before each run at all. It's becomes flaky when pace and gradient vary, though on the whole I find it to be within 2% of GPS, which is itself inaccurate.
As I run the same route through the winter (three or four days a week anyway). I will try the calibrate button after my next run and make the thing believe it has run 4.47 miles to see if that improves the readings.
I shall post back the results.
Well... I ran my usual route, 4.47 miles in 37. something mins and then 'Calibrated' the iPOD Nike+ thingy (as it suggested I had only run 3.3 miles).
I have had another run on the same course and... the thing told me I had run 4.49 miles. I'll try again tomorrow to confirm it wasn't a fluke.
Sunday - 5.46 miles. Nike+ mileage = 5.33
Monday - 4.47. Nike + mileage = 4.56
It seems reasonably close now....
Mine seems to be off on longer runs these days. The last 2 long runs I've done have been 3k and 2.5k out according to the map (nike+ being more generous) although it seems to be ok when I do 10k on known routes I'm wondering if my stride length is the problem when I get tired, or if it's just gubbed after a year of use and I should shell out for a gps device since I don't own a smartphone
I've been very happy with my Nike+ watch and footpod. It's to within a couple of metres of the My.Asics GPS app. Only issue I have is with using the footpod on its own. Tried it on a treadmill a couple of weeks back. Nike said I had run 5 miles, when I only did 3 and as a result completely smashed my PB for 1k, 1 mile and 5k.
Had to delete the run, although I did quite enjoy having a 4:31 mile on my watch for a short time
