“Margalla Backyard Ultra” follows the exact same format as the famous “Big Dog's Backyard Ultra”.
Runners must complete 4.1-mile (6.706km or exactly 6706 meters) loop in an hour until only 1 runner remains.
The bell will be sounded exactly on the hour and if you have failed to make the starting area before the bell rings, then you will be disqualified from the event and will become one of the many DNF’s!
There will be only 1 athlete who does not receive a DNF (Did Not Finish) and he/she will be the champion.
You will need to get your pacing right, as going too fast and you are going to be hanging around at the start waiting to go again, but take it too easy and you may find yourself working harder than you need to, to make the time limit.
