Hi Louise, we have recently moved to Dubai with two 13 yr old girls. One is interested in Athletics (400,800 & 1500M) and competed to a high level in Australia. The other is interested in Ballet (classical, contemporary & jazz) in which she followed the Cecchetti syllabus in classical and attended a competitive ballet school. Could you please recommend any places.

Take a look at E-Sports who offer Athletics.  The athletics season amongst the schools is just coming up so many schools will be training this term for inter-school competitions.  For ballet I would recommend you contact The Ballet Centre &  Dance Horizons
