I'm 14, 5'2" and I weigh 7.5 stone. As you can tell I'm fairly small lol;) but I play the wing a lot because I am fast but as I am sure all winger do I want to be faster:) Without a gym how can I improve my speed? I currently do a 5k or more run a day and I do that in an average time of about 26-27minutes so my stamina isn't bad but I new explosive speed? How can I do this?

Short sprints. Repeat them. 40m is all you need.

Its probably better to do sprints than a 5k. If your not going to they gym, you should probably considered doing 15-20 100M or 110 yard sprints with an emphasis on lengthening strides and finishing though the line as fast as you started.
