Welcome. Plenty of information, trainingb tips and debate on the forum. Just dive in.
Hopefully someone will be along shortly to give you a definitive answer to your question.
Meanwhile... as far as I am aware those living in Commonwealth nations are eligible to apply (subject to citizenship status, etc.).
I'm unsure of the current timeline for female applicants as it apparently changed towards the end of 2017.
Welcome to the forum! As Threadpigeons explained you're going to have to work to get that running time down. 10:30 may be the minimum but you want to be smashing that in order to make the course as easy as possible. I'd say sub 9 mins 45 is what you want to be comfortable hitting otherwise you'll seriously hang out on PRMC and not do justice to yourself.
