Today I went running slowly on purpose. By slowly I don’t mean at a pace that many of us might call “easy”. This was on the borderline between “jogging” and “walking”. I was inspired by an article in this month’s Runner’s World, which can also be found at fetcheveryone.com, about training in different heart rate zones and had been planning to give this a try for the past week.
This took place on Saturday morning when I planned to measure my resting heart rate by firing up the Garmin as soon as I woke up. I’d toyed with putting my heart rate monitor on before going to bed, but decided that despite 16 years of marriage, wearing an elastic strap around my chest under the duvet would take just a little too much explaining.
I think the lowest I managed to get my heart rate down to was about 39bpm but that took some doing after the excitement of the alarm clock going off mixed with the anxiety caused by the prospect of the morning’s Parkrun. I hadn’t worn the HRM for some time and doing it up and adjusting it suddenly put me in mind of Pat Wright and Dave Arrowsmith:
Once I’d finished amusing myself by talking in a poor Middlesborough accent about my “bra”, the next stage was to find out my maximum heart rate. With my 5K complete, as I clung on to a tree trunk until I was able to stand without support (that’s how we all recover from Parkruns right? Right?), I discovered that today’s effort had led to a maximum heart rate of 189bpm. Later on I programmed the Garmin with my personal heart rate zones in anticipation of the fun-packed geeky running activities that lay ahead.
Various domestic and work related stresses got in the way of trying my Slow Run until six days later, when working from home gave me the opportunity to do a cheeky lunchtime run in the style of Leonard from Butterflies. Despite the fact it was nearly dark at 2pm and pouring with November rain, I made it out of the door and set out to do about 4 miles in “Zone 2”, which in my case was 110-130 BPM. The point of running at this speed is that apparently you will be fuelling your muscles with fat and oxygen. Therefore you’re tuning up your aerobic system, it improves endurance and uses very little glycogen. Whatever that means.
The kind of speed I think I go when recovering from fast intervals turned out to be too fast. The Garmin kept shrieking at me: “Heart Rate Too High”, making the blood pump around my veins even faster with irritation. I started to run almost as if in slow motion. After about a mile I finally got into the Zone 2 Groove, possibly because I was now more relaxed and breathing more efficiently in classic, slow running style.
However this was soon undermined by a very gentle hill which got the heart rate up and my Garmin wailing again. Crossing the road, being close to lots of traffic, the sight of other human beings, wiping the rain drops off the end of my nose all seemed to increase the BPMs. Runners of various speeds overtook me, probably wondering why someone going so slowly could be so interested in his Garmin. Every time this happened I unconsciously sped up to try and catch them, only to be chastised by the “Heart Rate Too High” alarm.
I felt like I could have kept going all day but it all felt a bit pointless and the scenery wasn’t changing fast enough. I’d run at my slowest speed ever and it hadn’t been slow enough. My average BPM was 10 beats above target. What a failure!
After 3.5 miles I’d had enough. I pressed “Stop” and ran the mile or so back home at a “normal” speed, oblivious to what my heart was up to. A “junk mile” that felt so much better.
