Leisure horse

Leisure horse - Unfortunately and with a heavy heart I have to sell my jack - purely because of my life situation, because a few things have changed for me.
He is 7 years old and ran on the racetrack - two races, two last places - and so I was finally allowed to take him on.
After I took him on, I retrained him professionally in Parelli and did some conscious gymnastic ground work. He can now be ridden in the arena and cross-country without any problems. He has a solid basic training, long, quiet standing tied up, respect in any situation, hoof trimmer, vet, loading, washing area, traffic, none of this is a problem for him. Nevertheless, he is not a beginner's horse, he needs an experienced person for whom he is his one and only. He needs a clear guiding hand that knows what the next step will be in every situation.
An ideal position for him would be a group position where he cannot take the lead! He needs the balance of a group with his conspecifics/friends.
He is neither a bucker nor a climber. Under the right rider, with the right person, he is a horse that will blossom and go through thick and thin with you.
At the moment he is barehoof and is kept in a large group. He is more likely to be categorized as sensitive (right brain introvert)
He's a jack of all trades and sees the world with his own fairies and goblins, so I'm looking for a life partner for him who would like to go through life together. I would like him to find a place where he is accepted as he is.
