The relative newness of so many partnerships, in a sport that is all about the harmony between rider and horse, throws the form book of the competition away.
That’s especially true in the team competition. Great Britain, for decades the powerhouse of Para-Dressage, has never been beaten in a team contest at European, Paralympic, or world level.
And while no one would actively bet against them retaining their title this year, the path to British team glory is an untested one.
At last year’s FEI European Championships, Great Britain held off a strong challenge from a resurgent Danish team, with the Netherlands in third place.
Expect a similar tussle between those three countries this time round too, but add a strong German team, and the home advantaged USA into the mix as well, and who knows what could happen.
The relative newness of some previously well-established partnerships adds an extra frisson to the already supremely competitive individual competitions too.
Most of the Rio 2016 gold medal winning riders competing at Tryon do so on newer horses.
Great Britain’s highly decorated Lee Pearson, for example, competes in grade II on Styletta while his team mate, triple Rio gold medallist Natasha Baker, rides Mount Saint John Diva Dannebrog. Tryon is both horses’ first major international competition.
Other riders on new horses include Paralympic champions Pepo Puch (AUT), Michèle George (BEL) and Sophie Wells (GBR). And look out too for renewed attempts to gain world titles from the likes of Frank Hosmar (NED) in grade V and 2017 European grade II champion Stinna Tange Kaastrup (DEN).
