Thread title says it all. I'm running my first marathon Sunday at CIM. Never run more than 10 or 11 miles in my life. Haven't done any training runs in excess of 5 miles, most days closer to 3. But I have run every single day.
Over the summer I ran 16:30 for 3 miles off of similar training. I'm a 28 year old male.
Shooting for 3:30. Am I gonna be over or under?
