A devoted teacher is set to run 1000km to raise money for a charity who has helped support his pupil through his cancer treatment.

Alasdair Robertson, Assistant Headteacher of Wallington County Grammar School, is set to run 10km each day to help raise money for his pupil, Sachin.

Sachin Shah, 17, was recently diagnosed with a form of bone cancer called osteosarcoma.

The head boy has just started his second bout of aggressive chemotherapy and is set to have a knee replacement in the coming months.

Money raised will go directly towards, children’s cancer charity, CLIC Sargent.

Mr Robertson said: “I have taught Sachin since he was 11 years old and wanted to do something suitably challenging to raise money for a charity who has supported him so well since his diagnosis.

“Sachin is such a wonderful kid - he plays cricket and rugby for the school, and is a leader amongst his peers.

“He is humble, compassionate and diligent and has a genuine drive and passion to improve the school community.

“Sachin, his doctors, his family and I, remain hopeful he will survive and go on to become the extraordinary man that his talents befit.

“He is a truly remarkable young man who is much loved by everyone he meets.”
