I will point out, with the GSPs, that there are different lines (families) within the breed, pet, work and show. Those bred for pets, if bred by a breeder choosing health and temperament, ought to fulfill your requirements. A dog from one of the lines bred for work and protection will be more standoffish and have greater need for work. And although looking for someone who shows dogs is usually on the list of what makes a responsible breeder, given the current state of show GSPs I can't ever imagine one going running or biking with you.
Just want to add, although every dog is an individual and you can get a range of temperments in a single litter, the best way to predict a dog's temperament is to look at the parents and spend time with them if at all possible. Best, of course, is to spend time with the puppies themselves.
