Anil Sarpal, who lives in Tettenhall, will take on the challenge to raise funds for the NSPCC and the National Autistic Society.
And he is also raising awareness of the Teenage Cancer Trust following his own tumor diagnosis around 10 years ago.
The father-of-three had been diagnosed with a vestibular schwannoma – a benign tumour which affects the hearing nerves.
Mr Sarpal, who was diagnosed with Asperger’s two years ago, said: “I’ve had a lot of abuse and I basically want to make a change for people and show ‘you can do things’ – despite people saying you can’t.
“I’ve been bulled from primary school to sixth form and every single day I got bullied. I still get upset about it now – people said ‘you can’t be good for anything’.
“It takes me longer to do things but I want to prove I can do things like anyone else. I started to realise I don’t want anyone to go through the experience I’ve had to.”
The 48-year-old said he has already raised £2,000 for the Teenage Cancer Trust after his own experiences – leading him to commit to helping them.
He will take on the challenge on December 4 at St Thomas More Catholic School, based in Walsall, providing the current lockdown restrictions end.
Mr Sarpal said he was also preparing to climb Mount Kazbek – a major mountain on the border between Russia and Georgia in the Caucasus Mountains.
