The journey will challenge the ultra marathon runner to cover 442km, or the equivalent of more than 10 marathons.
‘I have been doing marathons and ultra marathons for the past four years,’ Mr Simpkins said.

Mr Simpkins is not just doing the Coast 2 Coast run as a personal challenge, he using it to raise money for The Centre for Cerebral Palsy in Coolbinia.
‘For people with cerebral palsy, mobility is a really big factor,’ he said. ‘I want to use my mobility to help people who face more obstacles to becoming mobile. I think it is a good pairing.’
Mr Simpkins will be joined by fellow marathon, triathlon and ironman competitors in running the final 10km from Perth Bell Tower to the Cottesloe foreshore.
