I think this is a great goal! Won't add much to what others have said. However, I will say, when it comes to training, the first month, maybe 2 will be fun and motivating. For me, hitting paces during workouts is definitely challenging, but it is nothing compared to doing it for months or years at a time to get to an aspirational goal. So I would advise sprinkling in some races to keep things spicy and break up the training! Good luck
