My first AOS also failed at ~80,000 miles. Which seems common from what I've read on here.
Sound to me like time was more the issue than autocrossing.

Also might want to do the waterpump or at least replace the coolant cap which has probably lost its seal if its the original. But do the water pump anyway. That failed at ~80K miles on my car as well. A bad AOS and/or waterpump are two things that can take down the engine. Well three if you count that old coolant cap.
