Event organizers can reject any entry which has suspect GPS data (straight line outside normal run route, unrealistic high pace like sub 3 min/km pace at any time during run, etc)
Event organizers have the right to take any decisions for disqualifying a participant if the participant is considered to have taken any external help in running the distance (like using a cycle or any other vehicle for a run), using a powered vehicle for rides or any external aid, or cheated in any way.
