According to Velominati, the Keepers of the Cog, Rule #24 of Cycling Etiquette states that “Speeds and distances shall be referred to and measured in kilometres“. They go on to say that “This includes while discussing cycling in the workplace with your non-cycling coworkers, serving to further mystify our sport in the web of their Neanderthalic cognitive capabilities. As the confused expression spreads across their unibrowed faces, casually mention your shaved legs. All of cycling’s monuments are measured in the metric system and as such the English system is forbidden.“
Rule #1 on the other hand states that you shall “Obey the Rules”
Therefore, I have little choice but to “Obey” and refrain from referring to speeds and distances in Miles but to refer to them in Kilometres.
Having said that, there is a serious point to this. In referring to Speeds and distances in Kilometres instead of Miles, I will become more accustomed to using those units of measurement. After all, whilst on the TDF or Bust ride, everything will be in Kilometres and with the real Tour de France starting on Saturday, distances and speed in Kilometres will become more relevant. I will also have the added psychological advantage of travelling quicker as there are 1.6 Kilometres to each Mile.
Looking at specific speeds which are of relevance to me, my itinerary for the TDF or Bust ride is geared around an average speed of 16mph (25kph). A very respectable turn of speed in training for me would be 19mph (30kph). A bread and butter daily ride is 25 Miles (40 Kilometres) and a long one is 50+ Miles (80 Kilometres).
Hopefully, it shouldn’t take long for these reference speeds and distances to become ingrained in my mind, after all, for the first 9 years of my life, everything was in Kilometres.
