HRM strap battery swap

Once again I spotted erratic heart rate data from the 935. On checking there wasn't any running dynamics data so the heart rate strap was offline.

I've just swapped the battery and according to the blog it's 3 years since I did it last. Can't complain then.

Maximum heart rate

For some time I've been using a maximum heart rate of 172bpm but this evening's run implies that I could be capable of being closer to 190bpm.

My attempt to have a decent pace along the Millhouses Park 1km Strava segment gave couple of points above 185bpm. Oddly I didn't reach anything like this heart rate ascending to Dore but there I'm limited by leg power too.

Certainly this run was better for not being over dressed although a pair of gloves would have made the time more pleasant. Looking back at my times on this 12km road loop I'm disappointed that I can't achieve times that I managed three years ago as a much more inexperienced runner. Is this due to being 3 years older or too many plodding-paced runs?

Very 'steady' 9km

OK, so last week's 13km with some effort gave me cramps. Two of 7km at various efforts on consecutive days were problem free. So today, after a rest day I went for a very easy 9km run. I made a big effort to have a fairly easy time and the heart rate data suggest that I achieved that goal.

This required walking up most inclines and a lot of glances at my watch if I felt the workload increase. It was a pity to return home with just 9km under my belt as it was a lovely spring evening and it was perfect to head further towards the Peak District.

I was aware of the quads of both legs above my knee and the left knee had its usual diffuse niggles, sometimes medially, sometimes laterally and occasionally in the patellar tendon. Presently that's juts being put down to 'hypersensitivity' as any joint that can cope with nearly 6 hours and 50km can't be that delicate.
