Data: the scientific approach


So what did I learn last week......in terms of the heart data there wasn’t any real surprises.  According to my heart monitor my average heart rate was 175bpm with a high of 183bpm.  This was what I expected and was consistent with the data from the ECG run in January.  The image above is sheet of notes showing the timings from my monitor called out to June and Hannah in the Lobby and the data the heart monitor/stopwatch recorded.

However the running gait was quite different.  I had laid out 2 x 20m and 2 x 40m lengths of lining paper in the Lobby.  During the run I ran on one of each of these lengths leaving beautiful prints from the dirt on the floor.   The delicate patterns embossed onto the tread patterns were printed clearly with the dirt of 160 years worth of dust.  However I fear that the delicate subtlety of the dirt on the paper wont translate easily into embroidery stitches.  As the prints were so clear after the run I inked up my trainers (Okay Hannah inked them) and I ran the steps again.

I deliberately waited until the second half of the run as I didn’t want fresh legs to give a longer than usual stride.   The big surprise is the length of my gait.  I had done some simple measurements at home and had been working on the assumption that my gait, particularly when I was tiring, was around 85cms.  However measuring my 'dirt' prints my gait  is between 115-130cms.

This means around 82 steps in a 100m embroidery.
