Bradycardia: If this significant drop in resting heart rate is unexplainable by medication or underactive thyroid,for example,, a 12 lead EKG is indicated to determine whether this is simple sinus bradycardia seen in athletes. You also may want to consider having a maximal treadmill stress test before this grueling race. Discuss this with your physician.
