In reply to Robert Durran:
The similarity of dressage to bouldering is the ability of taking the basic skills and movements of each to an extreme level. The ability needed for the climber to carry out or the horse rider to encourage horse to make moves in a controlled manner to be able to succeed in their chosen arena requires a high degree of mental as well as physical strength.
I have never been interested in dressage but can see and appreciate the skill required just as I can see the same in someone with the skills needed for any high end climbing including bouldering.
The idea that dressage moves are contrived is rubbish as they are moves that horses can and do carry out when out in the wild just that certain aspects are focussed on and training required when a rider sits on their back. It is the same for climbers, any move carried out is within the range of human movement just that training is required to achieve it on a regular basis.
So by making dressage and bouldering competitions appear contrived it is just a way of sorting out the wheat from the chaff. Those that put in the training get the results.
So speaks someone with a horse and climbs although not as well as either of the top two sports women.
