I have had several HRM and SDMs over the years from Garmin, Timex Polar and Suunto. All of them show lots of wonderful information, but mainly in tiny numbers that I can no longer read. I do not feel like carrying a magnifying glass with me on training runs, and stopping to put my reading glasses on also feels a little silly. Given the number of us over-50s carrying on and starting running, there must be a demand for widgets with nice big displays. Can anyone recommend one?
