The 33-year-old is taking part in as many obstacle courses as possible to raise funds for Beyondblue after a close friend took his own life earlier this year.
‘I had known Mitchell for about 17 or 18 years,’ he said.
‘The last few years had been quite tough on him, relationship breakdowns; he lost his mother plus other issues from his past.
‘His death came as quite a shock to everyone involved, it was only earlier in the month I had spoken with him and he sounded like he was doing well.’
In order to make the challenge more interesting, Mr Titterington will complete one of toughest courses twice.
‘Tough Mudder is one of the hardest courses on the race calendar,’ he said.
‘The idea of doing it twice came out of wanting to do something most people know is challenging but taking it to another level.
‘I am aiming to initially raise $1000 but anything on top of this would be a bonus.’
