Running with friends

I've never been to America, my dream was always to visit New York. I have some admiration for the city, for the people living there, for its skyscrapers, for The Central Park, for its multiculturality. Almost three years ago I started running, I could say accidentally, my friend got me into running and I was like...ooo I could give it a try..probably nothing will be out of that but I will give it a try. And now, three years later I'm still running..I've run a couple of half marathons and I'm being better and better. Talking casually with my friends, planning our next run we started to thinking how cool would it be if we go together in America and run New York marathon. Our friend gave us a piggy bank to start saving money for the aeroplane tickets, for the registration fee and we need visas, we are from Zagreb, Croatia (Europe). Getting there is a bit expensive for us so if you are able to help us a bit we would be soooo grateful!
