    What smartwatches/HR monitors do you use to pace?

    I'm looking into smartwatches and heartrate trackers for HR pacing as my Samsung watch stopped working... Which ones do/have ya'll used, and are they any good? Please share any recommendations, opinions, info you have to offer in the comments 🙂
