My coached informed me that I will be running my first 800 this year. I am a sophomore in college and have never really seriously attempted the distance. I have always considered myself a 400 meter runner, but have not seriosly advanced in my time in over three years. I can run a very consistend 47.low 400 meters. I do not run a lot of mileage. I run maybe 20 miles per week and my long runs are only at 35 minutes. What are my chances? I am thinking about telling him that I do not think it is a good idea. Oh and by the way I am 6'4 and weigh in at 171 pounds.
