Struggling on my bike ride home from work the other morning I had another tractor slip streaming session. I had the impression that cycling behind the tractor made life so very much easier. The average speed per mile as shown below in the geeky table bares this out, rising from about 15 - 16mph to 25mph.
It surprised me that my average heart rate went up by over 30bpm as well though. This surprised me because a lot of the time when following the tractor it feels as though I am practically coasting. It is necessary to really gun it when trying to keep the wheel up an incline but then on the flat and downhill It felt as though I was just ticking over giving the overall impression that it was easy.
I suppose this just goes to show how much speed and performance is in the mind. With a bit of motivation I was able to raise my average heart rate to 160bpm in order to stay in the tractors slipstream, where as before the tractor came along I was struggling to get the average up to 130, convinced that I couldn't go any harder. Unfortunately I seem to need a tractor to motivate myself.
