Sat in the car waiting to get out there and enjoy Storm Hannah at parkrun and I read this on BBC News
Fitness trackers 'add miles to your marathon' bbc.co.uk/news/technology-4...
Yes, Which did the test on a treadmill, which I guess they didn’t tell garmin as their response was that the tested device didn’t have GPS.
Unless I’m missing something, it’s always going to be a guesstimate indoors.
Anyway... off to go get very wet and embrace the wind.
Brave going today, it's shocking where I am. Take care 💨💦🌪🌩🌬
The storm was nice to us... heavy rain stopped at 8:35... light drizzle at the start... dry from mile one for me... of course some of the super fast guys ran most of it in the rain 😂😂. Wind dropped... then at 10 the weather was atrocious again.
When I first bought my Garmin Forerunner, my treadmill runs were super fast! I was smashing 5k in 23 minutes. Once I added a foot pod and had a few outdoor runs to calibrate it it soon realised that I’m super slow as opposed to super fast!
😂. The big thing is being super happy at the finish line... or maybe shortly after!
I read that too, one they tested was 11 miles out over a marathon distance, how can that be?!
It does seem a bit far... but they don’t say how they knew the treadmill was correct either... most aren’t
👍
According to LU sports expert, lost opportunity not to have done the test in the real world outside.
Such results would have served runners well.
Atb with Parkrun.
👊💥🏃♂️🌟👏👏
Yeah, I just don’t get why they didn’t just walk 26.2... who runs a marathon on a treadmill?
We have to award Which! 10/10 for sheer stupidity. They claim to be the consumer champion but tested fitness trackers and running watches for accuracy over distance on a treadmill. That demonstrates their total lack of understanding about how these gadgets work.
An activity tracker without GPS is always going to estimate your stride length, count steps and then work out an approximation to distance covered. It has got no chance of being accurate. But if someone bought an activity tracker with no GPS, they are probably only interested in step count..
An activity tracker with GPS is going to calibrate its estimate of stride length during runs outside. It can build up a pretty good knowledge of your stride length at different running speeds, and then when used on a treadmill it is going to be more accurate. BUT... this relies on a period of calibration/training and the Which! report probably did not wear the activity tracker for 1 month in a variety of outdoor, gps-monitored runs before the treadmill test. So again, the Which! results are pointless.
Lastly, a running watch with GPS, optical heart-rate etc is going to be similar to the activity tracker with gps. But anyone buying a gps running watch is not going to run a marathon on a treadmill and care about the distance reported on the watch. So that is another Which! stupid test.
I’m wondering if they did the run in one go or had a relay going.. surely if they had marathon runners they would have just tested them this weekend! Of course they’d all have to run the blue line. As soon as they go relay even calibration of the device would be pointless. I do love an obviously flawed piece of science! Of course Apple Watch series 1 resale values have just risen 😂
are you selling your watch?
Even more flawed science - no doubt they had a range of testers, each testing 5-10 trackers over a period of a few weeks. I doubt that one runner tested every tracker and so this just adds another level of variance.
Nope... I’ve resisted Apple Watch!
Hope it wasn’t too bad out there.
It beggars belief really that they thought test them on a treadmill was a good idea 🤦♀️
The weather was really kind... all eased off... light drizzle for my first mile and then it stopped... stormy again at 10ish.
Oh good. I drove through horrible weather to get to where I was running, and thought we were going to end up running in the rain, but then the skies cleared again as I arrived. 😊
Somebody somewhere likes us!
We deserve it 😉😉😉
I hope you haven't been blown away this morning. It's horrific here!
We got a lovely break in the weather, which returned during the post run coffee 😀
I had my 7s in almost perfect condition. Warm, bit not too much, and hardly a breath of wind. Not often Scotland gets the good weather...
Most unusual!
I’m back after 2 months of no running
