On Friday, Harrie Smolders announced the retirement of his winning partner Regina Z. During her successful career, the 16-year-old mare by Rex Z x Savoy Hanover won countless of competitions with Smolders in the saddle. Some of their biggest victories include the 2015 Longines Global Champions Tour Grand Prix of Shanghai and the 2014 World Cups in Las Vegas and Del Mar, but the two also have five-star wins from Lausanne, London, Valkenswaard, Falsterbo, Chantilly, Hong Kong and Basel to look back at. Here is our tribute to a true winner, as we wish Regina Z a happy retirement! All photos (c) Jenny Abrahamsson.
