"On the marathon and in cones, nobody on the top level drives Achenbach anymore, but everybody drives two handed there, and while years ago there were still discussions about it, by now there is really nobody in the top of the sport arguing that one could be successful on the marathon and in cones with Achenbach. The two handed method is just quicker.
In dressage itâs different."[/QUOTE] Thereâs Achenbach AND then theirâs coachman rein handling.
The fact that no one now drives other than two handed doesnât mean that itâs quicker or better at all.
You need to appreciate that driving suffered from a huge loss of core skill base and to such an extent that the Horse Driving Trials Association were concerned that there werenât sufficient drivers to compete.
So they just changed the rules!
Now for me driving coachman is just what Iâve done from being a child, so itâs instinctive and itâs what I do - always, everywhere. Including at the World Equestrian Games when I went there. In those days there were several drivers who drove EITHER Auchenbach or Coachman.
The times were no slower.
Iâve got a long standing bet that I can take a single or pair of horses quicker through a cones course driving coachman style than any driver doing it two handed. I allow the challenger to set out the course and to date though I have on average about 2 challenges a year Iâve never failed to take the ÂŁ50 (singles) or ÂŁ100 (pairs) donation for Leukaemia Research.
Providing youâve honed the skill of single rein handling then thereâs absolutely no reason why it should be slower.
However you also need to appreciate that driving a cones course or a hazard on the marathon phase is NOT purely about speed. If it was, then it would all be at gallop!
Itâs about accuracy and precision and flowing movement through the hazards/cones. That means there should be no stopping, starting, pulling and heaving and constant corrections on the horse.
I know thatâs all too often what you often see but itâs not what drivers should strive for and itâs not what is to be attained.
