The Muriel 6 Challenge 1 – The Spanish Horse opens the series with a stunning display of horsemanship. Set against a rugged Andalusian backdrop, the challenge introduces Muriel’s unique bond with a purebred Spanish stallion. The task: navigate a winding mountain course using only subtle leg and voice commands – no reins. The video captures every tense moment, from the horse’s wary first steps to the triumphant final gallop.
