On a good day, I can run for an hour or so without needing an ambulance. I’ve noticed that it’s enormously easier to keep running if I don’t do the instinctive thing of lowering my chin to my chest and ‘digging-in.’ My assumption is that lifting my head allows easier breathing, but whatever the reason, this really helps me cover ground with very much less effort.
Today’s invention is a neck brace -just like those used by people with whiplash injuries, except that this is an ultra-lightweight version with multiple air holes in it to avoid temperature build-up during exercise.
This might also be combined with a pair of sunglasses in which the bottom edges of the lenses are completely obscured -forming vertical blinkers which discourage the tendency to stare at the ground a metre ahead.
