Artificial Sweeteners, DIY Race Tips, Nutrient Timing and More – Ask a Cycling Coach 294

I’ve seen it on three different Wahoo HRMs. I usually track HR on an apple watch, too, but forget to check it. I spend a lot of time staring at my numbers on my head unit or TR app, so I def. see it there. I think I remember it happening with an old Suunto chest strap, too, but it’s been a few years since I’ve used that one.
