There is an average range of height that an average 12 year old girl would fit into but people develop in height faster and slower than others.
no. but running oustide is better and will help lose weight faster and better
11-13 seconds is a great time, but most girls run it in 14-16 seconds I'm 13 and I run it in about 11-12 seconds, I'm the fastest in my year but there are other girls from other school which are faster than me. Most of my friends run it in about 13-15+, so that's probably about average.
