Is this possible? Major D1 Program walk-on?

Probably not if it's as major as you say it is. You have 0 chance of hitting 1:54 in 9 months. You would probably need to run at least a 48 in the 400 too.

It was 15 years ago, but I walked on to a top 10 D1 program with a 1:58 and 4:30 HS mile. Dropped to 1:54 my Freshman Year and eventually to 1:49. I didn't run the 1500/Mile much in college. So, it can be done.

Thanks for the input guys.

For some reason I think I could pull it off. That is probably me just dreaming though.

sure you have a shot. Who knows what 9 months of training would do for you. Going from 0 to 2:01 in 3-4 months is decent talent. But no one can tell you what 9+ months (Well the question is are you in 2:01 shape now or more like 2:10?). The downside is that you will find getting into races hard, you need to come up with a solid training program (your HS one likely sucked), and running lot of hard running by yourself is something that a lot of people don't like doing.For what it is worth, the 4:20 1600m is the much easier time. Dropping 20s by building an aerobic base to go with your decent speed and anaerobic endurance in 9 months is possible. Given your speed to 5k times, it is pretty save to say, you were running a low mileage program.Train hard for 9 months and you will know if you are good enough or not. That being said, being a 1:54 or 4:20 guy at a major school isn't much fun. You are not going to very many meets and you are basically hanging around to see if you can be a 1:50 or 4:05 guy in a couple of years.

Thank you for the detailed response df! Much appreciated!

That is the other thing... if I can actually do it, I need to figure out if I actually *want* to do it.

Not enough information to really say here. One year of track and XC isn't much but did you have a fitness base from other sports? If you had a big soccer background then your upside potential would be a lot less than if you did nothing until deciding to start running.

I did not play soccer. All I played was basketball for 2 years.

I don't have any runners in my family. There is a fair amount of athletic talent in my family though.

Several family members played collegiate sports.

I have been considered "fast", having been clocked at a 4.7 40m.
