Hey LRC,
I'm about to graduate college in a few weeks which means wrapping up a college track career. I'm a middle distance guy but am looking to move up to longer stuff because it's more conducive to the ex-college, social-running life, plus I'm ready for a new challenge. Is it possible for a solid middle distance runner to move up to the marathon? What would it look like? If it matters, PRs are 48.8 400m, 1:50 800m, 4:13 full mile. Thanks ya'll.
Dude you've run a freaking 4:13 mile which is a primarily aerobic event, you'll be much better than the average marathoner. Just make sure to be strong enough to handle the overall mileage demands the marathon asks of you and start doing some marathon specific workouts and you'll surprise yourself.
48.8 and 1:50 means you have the speed. Another few seasons, cop that 3:59!
Do your strength training, keep lifting 2-3 times a week, stay healthy, keep grinding those miles and you should be alright!
