Sub 1:30 half marathon training plan/strategies?

Hey guys!

I have my next half marathon coming up on May 18 (8 weeks from now) and I want to finally go sub 1:30. I just ran the NYC Half where I did 1:32.

Do you have any suggestions on a shorter training plan that I could follow to get that little bit faster? Or what strategies should I incorporate to bridge that gap?

I’ve been averaging 25-30 miles per week for half marathon training generally.

Any advice would be much appreciated! Thanks!
