It seems that it is not the watch that is the problem but me as increasingly struggling with runs despite considerable improvement in conditions; 6.30min/km pace feels knackering. Booked in to see doctor next week but today nurse checked my blood glucose (5.9 so normal considering I had just had my breakfast), haemoglobin (lowish end of range but not below) and crp for infection (no sign). Will see what doctor says but nurse did suggest thyroid problem.
I have been wearing a long sleeved top and long sleeved jacket! However, will give it a go on the inside of my wrist.....that is in a few days after the ankle eases up. Think the 16km on Saturday did it no favours then this morning's skate about on the ice and trudging through icy snow before hobble jogging home sadly .
Gideon Levy - no offence was taken, do not worry . Your explanation makes perfect sense and tried the watch at the tightest setting this morning but heartrate still high. Now wondering whether I am anaemic as feeling more tired than normal and noticed insides of eyelids are pretty pale this morning. Weird considering I love liver, eat red meat at least once a week, loads of leafy greens and not much caffeine. Or maybe I am just an unfit, lazy arse after all.
Anyway thanks for all the suggestions, greatly appreciated
It does seem odd actually as usually my easy run pace is between 5:50 and 6:10 even on forest trails and over up to half marathon distance so to be doing 6:30min/km for 6k is a bit strange even with injury and icy conditions....hmmmmm. Will test on other wrist and see what happens!
It is the TomTom so will try warming up more as it does sometimes give me a warning to do just that. I have only had it a couple of weeks. I have been wearing at the second tightest so at least have one more set of holes to tighten.
Gideon Levy - even though I am far from my fittest I would not say I am unfit given I am running over 40km a week, cycle/walk 6-10km a day and do yoga a few times a week. My resting heart rate is also pretty low and my BMI is about 18 so not anything near overweight.
