After countdown on pixel watch 3 run doesn't record

[Mouldyboot]

Hi I'm doing a treadmill run, get to point where countdown starts. I start running but 5 minutes later the watch says " are you doing an activity? Would you like to record it?" Because the watch has lost my run. I miss pressing the right button in the seconds I'm given by the watch to respond and then I lose my run.

Would be great if I had one visit to the gym where I don't have to post another glitch!

Hi, @Mouldyboot welcome. When you start running on the treadmill and before the watch says " are you doing an activity", is your arm swinging freely, or are you holding on to the rail? If you are holding on, the PW3 will not detect the start of the exercise, thus the question. May I suggest you try it again, but make sure your arm is moving naturally.

How it works

• Start the workout manually: 

  To get the most accurate data, manually select "Treadmill" from the Exercise app on your watch before you begin your workout. 
• Measure motion: 

  The watch's accelerometer tracks the motion of your arm to count steps. 
• Measure heart rate: 

  The optical heart rate sensor on the back of the watch monitors your heart rate throughout the exercise. This is a key metric, as it helps estimate your exertion even if the distance or step count is not perfect, and it's used to calculate things like Active Zone Minutes. 
• Use machine learning: 

  The watch uses machine learning to analyze the sensor data and provide a more accurate workout summary. 
• Broadcast heart rate: 

  Your Pixel Watch 3 can also broadcast your heart rate via Bluetooth to compatible treadmills and other fitness equipment, which can help you see your stats on the treadmill's display. 
• Challenges with accuracy: 

  The watch may struggle to accurately track distance and steps on a treadmill if you hold on to the handrails, as this reduces arm movement. 

  I hope this helps, please post here again & let us know how you get on.

  Cheers
