The quote below is the only detail about this event:
300KM FINISHERS ARE NOT YOUR TYPICAL ULTRA RUNNER, THE TERM ELITE IS NOT EVEN ENOUGH TO DEFINE THEM, BECAUSE THEY RESEMBLE MORE OF THE SPARTANS WHO KNOWS NO FEAR, WHO KNOWS NO LIMIT, WHO KNOWS NO SURRENDER!!! IGU 300 WILL BRING OUT THE SPARTANS OF ULTRA RUNNING, THE QUESTION IS, DO YOU GOT WHAT IT TAKES TO BE ONE OF THEM??? I’LL SEE YOU ON NOVEMBER 30 SPARTANS!
This is a run for elite runners. A run organized by iRunner and it will definitely bring out the best in you.
