TomTom has released this genius little watch called the TomTom Cardio Runner. Most watches use separate, wireless sensors that you strap around your chest. These can feel a little restrictive when you’re breathing heavily and get very sweaty.
The TomTom Cardio Runner has no straps at all and the heart rate monitor is done via the 2 green LED’s. You can read all the technical info here and in the meantime you can watch this video of Alexandra Morgan running strapless in slow motion (brace yourself boys your in for a treat)…
