I want to runaway but I'm not sure how or where im going?

My sister is 21 and she was my bestfriend, she moved out last summer. We moved from new jersey. Now it's been a year, and my parents are wanting me to play football and get involved in activities which is understandable. But I DONT WANT TO. I tell them all the time, im not the athletic type, i dont fit in with these stuck up people, I dont want to play football or anything. I dont fit in because they moved me in march, and now march, april, may and now we got out of school in june, i still dont have any friends. Im trying.. but i miss my old life too much. Every day i go to football practice and basically work my *** off and it seems like i just put myself through more pain because my body is not used to it. i dont want to do it at all, but my parents push me to do it even more. they call me a quitter at every sport i tried, but they just dont seem to get it. Maybe they'll take me seriously, if i runaway. the escape will be easy, but once im on the street how can i get away without getting caught? I plan on returning. But i just want to know where should i go, what should i do? i definately want to return, but i just need to clear my head.. i feel like a failure and ill let my family down if i refuse to do football, but then i will never fit in at school... idk im stuck i need serious help... they also said i refuse to do it, then i will be doing chores all day long,and theyll make life worse... so im stuck,
