Hi,
I'm new to running- I'm on week 8 of the Zenlabs Couch to 10k programme, and use my app when I'm running, and it stores the mileage at the end of each run, and calories burned. I've also just got myself a Garmin Vivo move smartwatch, and also used this on my last two runs, and it gives more detail about mile splits, etc. However, the distances recorded seem to be really different - I've just got back from a run, which has been recorded by Zenlabs as 2.15miles (about 3.46km), but the Garmin has recorded it 4.32km? I'm not sure which device to trust. I ensured to start and stop the Garmin timer at the beginning and end of the actual run, so didn't included the warm up/ down walks. According to the app, I should be running about 2.5miles now, in 25mins, so if the app is correct, rather than the watch, then I'm a way off the pace still.
Which would you trust?! 🤔
