I was just curious so see if the Marathon is something I should pursue once out of college. I'm only 19 years old but have a 1:14:20 half marathon as a pr. I've also run 20 miles in 1:58:35 for a long run. I tend to better at longer distances on the road where I can just go out and keep hammering away and my high school coach (2:16 marathoner) thinks I have what it takes. Any advice on what I should do??? thanks
