Can I walk-on to a D1 XC program at 31 years old?

Bc the 18-22 girls would start to notice…

I think 11:00 for female 3000 steeplechase is actually a reasonable time for the NCAA. I mean it's not making any of the competitive teams, but many teams struggle to even find women to run that event. But its a bit strange to be able to run an 11:00 3000 steeple but only manage a 5:48 mile, so I'm a bit skeptical. Basically your flat out one mile pace and your 3k steeple pace are the same, which makes no sense.

She said she ran a 11:00 3k steeple, that way way faster than Martina-Rodriguez-Villen. I find the steeple time a bit suspicious compared to the others, given how much better it is, but maybe she was a steeple specialist who never really ran the other distances (but if so, why not just lead with I ran a 11:00 steeple, why even include the far worse times)

If NCAA schools are reticent about you due to your age and complex eligibility situation, coupled with your times probably not being fast enough to incentive sorting through that tangle, an option could be the NAIA. Eligibility requirements are much more lax there, and your times might give you a shot to even make a top 7, which might be more fun than just being a walk on.

In the 1970s your eligibility started when you were a freshman and ran out in four years whether you ran or not. But, I know they are more forgiving now.

start training again and see what you are capable of

I am sure there are coaches out there willing to take a chance on you, but I think it will be helpful for them if you have run some races in the past decade to give them an idea of where you are at fitnesswise

if you're going back to school you may as well get to enjoy the running part too!

Well, I think they have already recommended everything that has been and will be, I hope you have been able to find what you were looking for
