Your watch doesn't know how you feel.
That doesn't mean you should ignore the data or throw away the technology. Wearables can give us incredibly useful information about sleep, HRV, resting heart rate and recovery, but none of those metrics tell the complete story.
The same is true during training. Your powermeter or lactate monitor might show you're 20 watts below your normal output, your GPS watch or swim clock might tell you that you're slower than expected. That doesn't automatically mean you're losing fitness or that something is wrong. You might be carrying fatigue, under-fueled, dealing with the heat, or simply having an off day.
But the opposite can also be true, too. Your recovery score might say you're not ready to train, yet you start warming up and feel great. This is where athletes need to become more honest with themselves and better at understanding what they're actually feeling. Not every bad day means you should stop, and not every good score means you're ready to have the workout of your life.
Start the workout. Pay attention to how things develop. Then use the data to help you understand what's happening, not to make every decision for you.
Your watch gives you data. Your body gives you context. Learn the difference.
