LAUNCESTON'S Cataract Gorge was the late Bob McMahon's oasis and to see it host a multisport event was his dream.
In 2012, Mr McMahon, Ian Ferrier and Cade Smith began plans for tomorrow's first Launceston Cataract Challenge to be held within the Tasmanian landmark.
Sadly, the famed rock climber died suddenly in April before his dream came to fruition.
``The Gorge was his office, he was here frequently climbing and abseiling,'' Mr Smith said.
``The dramatic beauty of this iconic destination was never lost on him and he wanted to share it with everyone.
``It's going to be a fun day, that's the way Bob would've wanted it - this is our tribute to him.''
To honour Mr McMahon the male, female and team winners will be presented with the Bob McMahon Memorial Trophy - much to the delight of his widow, Susie.
Mrs McMahon will perform with the Launceston Symphony Orchestra at the event, while their grandson Laurence McMahon will take part as a competitor.
Mr McMahon named most of the more than 2000 rocks to be climbed in and around Gorge.
``I am just so pleased that it (the challenge) went ahead after Bob died so suddenly,'' Mrs McMahon said.
``He had a lot of unfinished business and just to have something he will be remembered by for this area of his life - I just think it is wonderful.
``Bob always saw the Gorge as a potential for an event like this and he was just so excited it was eventually happening.''
