Ran a 3:56 1500 as a college running club freshmen, 55 mpw, good enough for NCAA D1?

Yeah, you could basically walk on at any school not named Oregon/Stanford/Ole Miss.

Good luck!

Teams have roster limits so it isn't quite as easy as you think to walk-on. Start checking though and you will find many schools that will take you.

Yes.

At most ACC schools, you’ll travel as a miler

Its more about consistency. Can you do it again and again?

Of course, man. I ran 3:58 and was a full-scholarship DI guy (of course 1500m was not my specialty).

At a top 20 program, it might depend on the coach and if they have some space for developmental runners that do a lot of local meets but don't really travel. Any other program would probably be glad to have you and you would get to travel and might get some scholarship money.

In that same season I had run 4:02, then 3:59, then 3:57, then 3:56, then 3:56 again so yeah I was consistent I think

YES but get above an 800 on your SATs okay son?

Yes for almost any mid-Major. Probably even competitive for a small scholarship at most DI schools.

Probably would not be given an opportunity at most Power 5s though.

Really what you are asking is if this is good as an incoming sophomore into a program. I'd say it's solid, especially if you still have a red shirt available.

I am not aware of any P5 coaches who would take you. They are restricted by roster limits and you wouldn’t be in their top 4 in either event. If you ran those times as a junior in HS on 40 mpw, that would be different.

Everyone sees 3:55 and thinks oh there are tons of guys 10-20 seconds faster. But I would bet there are just as many 4:00-4:15 guys or more in D1 as there are 3:35-3:45. Lots of bad runners go D1. Or lots of runners go D1 and get bad. You can certainly make lots of teams but the tricky part is finding who would take you. I doubt you get much $ as a transfer.
