Never to late start... find your equine discipline and go for it!
Its depend from jour trainer. you can good begine to ride if good teacher will have,but in hobby klass.Who from birth begin to ride like me, we more can feel horse and to be very up in sport. I had one student,he had 36 years and he tried the first time ride.I began train him and after 1 year he go to capital city on challenge and got 3place from all riders amateur who jumped the first time.He was happy till sky)) he didn't believe that he can do this in his 37years old.So dont worry 😉everything in your hands.But remember you can be like amateur not professional!!
