I read on here that many of you average about 19 mph, i can only manage between 12 - 20kph (on flat) what am i doing wrong and should i worry, i do push myself could i be in wrong gear or is it just old age !!
Anyone who averages 19mph across flat terrain is quick. Across varied terrain they are very quick and across terrain that is very hilly they are plain *loody quick.
As the Marmoset from Deptford says - you are comparing yourself to what are in effect very fast riders.
Many people no matter how light their bike and how hard they train will never achieve those average speeds.
I did my first 15mph average yesterday and was well chuffed (slipping easily into modern day vernacular). I am quite fit (I do a lot of mountain hiking/scrambling) but I seriously doubt whether there is another 4mph in me esp' in the terrain up here. Do I care - not a jot! There's lots of ways to measure the worth of an individual and cycling speed does not rank too highly on my list.
I'd just crack on a not fret about it at all. I infer that you are an 'older' rider (I am too, clue is under my avatar) and long ago I got used to the fact that in all aspects of life no matter how big a dog you are there will always be a bigger dog out there somewhere!
