The Ausdauerpruefung ( AD ) you refer to is 20 Kilometers about 12.5 miles.
There are 2 breaks ( ? ) and used to determine the well being of the GSD involved, the handler is riding a bicycle, not running. At each break, the judge will check the dog for any signs of fatigue, wear and tear to the feet or injury. If a dog shows signs of being overly tired or injury to their feet, they will not be permitted to continue. The pace is 7.4 to 9.3 miles per hour for all large dog.....considerably faster than you are running. The first break is after 5 miles for 15 minutes...the GSD is evaluated and then continues on another 4.3 miles and takes a 20 minute break...evaluation again..and then completes the 12.5 miles....short break and then obedience test.
I believe this endurance test is successfully completed by thousands upon thousands of GSDs over the years which get their SV standards rating for breeding in Germany. The AD is but one of five requirements involved.
I have found other information which somewhat contradicts the info mentioned above regarding breaks..... The original SV standards for breeding are cited below with their standards for the AD...notice one break.
I am not certain of the minimum age but thought I had seen 16 months.
I might consider the surface they are running on as a factor.
I would guess if your dog has already been acclimated to the distances you mentioned there is no reason it cannot be increased over time. You are the best person to evaluate your dog's ability and if you feel the dog is capable than enjoy her company.
If there was 10 healthy GSDs or certain other breeds competing against humans in a half marathon, my money would be on the dogs schooling the humans.
SV Standards for Breeding:
The BH or Begleit Hund (Companion Dog) is the first foundational title required for breeding. It is a test of obedience, temperament and neural stability in challenging situations. It encompasses extensive patterns of on and off leash heeling, down, stay, sit, here commands and traffic/noise/other dog distractions.
Now required by the SV on both hips and elbows, the "a" stamp is an orthopedic evaluation that requires no allowance of either hip or elbow dysplasia in the dog presented for x-rays. The x-rays are rated in Germany by university-based orthopedic specialists.
The AD or Ausdauer Pruefung is the next step in the breeding equation. This is a 12.5 mile endurance run with one break allowed halfway through. It is performed on ground/grass rather than hard surfaces, typically on bike trails with the handler on the bicycle and the dog running along side. This is part and parcel of the standard that the GSD should be an upper medium sized dog who can cover ground efficiently for extended periods of time without breaking down.
These are also required for breeding and conformation show ratings. There are three levels, I, II, and III and are increasingly complex tests that show the ability of the dog in obedience, agility, tracking, and courage. They are designed to measure the intelligence, utility, stability and trainability of the dog. Without a minimum Level II title, the dog cannot receive the most coveted conformation rating in the show ring of VA (Vorzuglich Auslesse/Excellent Select.) To achieve this rating a second time, the dog must possess the most advanced Level III title. Conformation ratings from the show ring are also required to participate in the final step for the allowance of breeding, the Koerung.
Koerung (Breed Survey):
The Breed Survey is performed by a specially certified Koermeister (Breed Master.) It is a combination test of workability, neural stability and conformation (correct structure and physical type according to the breed standard.) Dogs who are recommended for breeding will achieve the ranking of KKL1 and suitable for breeding KKL2. If the dog does not pass the Koerung, it is not allowed to breed. It must pass this test a second time in life to achieve the rating of recommended or suitable for breeding for life, thus achieving the Breed Survey status of LBZ (Lebenzeit.)
As you can see, the German SV Standard is quite exacting indeed, and the most rigorous set of requirements for any breed of dog worldwide.
