Well, yeah, what the guy above me said However, if you are VERY VERY patient, you can perfectly train a pokemon in attack and speed pretty early on (goldeen for attack, woobat for speed), so if you fight only Cain and Victoria with your starter, catch the first guy pokemon you find and train it to absorb other EV's from trainers to get to the spots, you can train yourself a Uber Blaziken-EV-set (on your torchick if you picked it), for example. It isn't necessary, though. EV's give you an edge, but that edge can be gained (sometimes easier) with strategy.
