There are a few clubs in the US that I know of specifically but I’m not sure if they would allow you to train with them probono. Your best bet might be to train with a coach at one of the Universities that have a very respectable program but as far as the financial situation is concerned, that’s a whole other issue. I know Europe has a circuit system that most of the runners use to make money but once again, how to get on the circuit is a mystery to me. If anybody knows more info please post!
