My only worry here is you’re running so well that there is that slight risk of going off too quick. It’s easily done. So I would focus really closely on the pace in that first half mile to make sure the watch says 6:20 or above. I’d rather you start off a bit more conservative and finish strongly than go off to fast and really struggle at the end. I think you’re in PB shape, but there are never any guarantees and the one thing that could prevent you from getting that is too quick a pace early doors. So just hold back, even if it feels easy to being with. Then if you’re going to hit 6:10-6:15 pace, make that the last few miles. Plus if you knock too much off your time, you’ll make it that much harder to beat in the future 😂 But what I do know is how well you are running right now and that you’ll leave it all out there on the course, regardless how tough it gets and for that I admire you so much. Go and smash it. You’ve earned it. Good luck Paul.
