I completed the couch25k yesterday!Feeling very pleased with myself but need some advice. I’ve just had my 61st birthday and was given a fitness watch just in time for my final run. I was shocked to find that my average heart bpm was 156 for the 30 minutes! I l know that wrist monitors are not always accurate but still...! I do find it very strenuous but seem to recover quite quickly. According to the experts my maximum heart rate is about 160 (220 - age), and it’s recommended that you work at 50 to 85% of that number. Which for me is about 130 at the most. My question is, how many of you runners around my age, manage it without going over 130 bpm? Sorry for such a long post!
