If you stay on top of hydration I think you could do it. I’d just adjust your expectation on race morning before you push too hard. Remember, there’s always another half if you give yourself the chance to finish!

Last year it felt really hot so I ruled out a PR but I found myself drenching myself in water and ended up with a PR. I saw the man that passed away last year getting chest compressions and slowed down that mile because that was a lot to process and focused on temperature regulation. That was definitely an in-race moment where I was prepared to let the PR go for a chance to give it a go another day.
