Australia's hardy band of triathletes were out in force today for the Aquathlon events on the opening day's competition at the ITU World Triathlon Championships at picturesque Hawrelak Park.
From 16-year-olds Elle Stevens from the Gold Coast and Jason Yerbury from Bexley to 77-year-old Canberra marathon man Lachlan Lewis and 70-year-old Yamba retiree Ray Hunt they hit the ground running in the hot conditions that have greeted almost 3000 triathletes from around the world to the Alberta city if Edmonton.
Jason Yerbury was joined by older brother Ryan, 18, who described him self as "the apprentice" in a family affair who "adopted" Bega born former swim star Andrew MacNamara - a PE teacher from Holroyd High - for the day.

And they were equally inspired when Andrew spoke of his courageous comeback from a horrendous skiing accident in Japan in 2009 which left him with two broken femas and requiring two double knee reconstructions leaving him on crutches for 18 months and bringing an end to his Olympic swimming aspirations.
A budding former 50 and 100m sprint freestyler under Elite coach Tony Shaw at Sydney Olympic Park Aquatic Centre, Andrew took up triathlons with the encouragement of his physio team at Sapphire Coast Physio.
Competing in triathlons was the furthest thing from his mind and representing his country in this week's Age Group World Championships is a dream come true.
Triathlon certainly brings people together like Elle Stevens and fellow Gold Coaster, Griffith University student Jacinta Smithers and Ella Connaghan from Manly who attends one of Sydney's most decorated sporting schools, MacKellar Girls High.
Also an emerging single scull rower who lives by the adage "that MacKellar Girls can do anything."
But if it's longevity that's inspiring then 78-year-old Lachlan Lewis is your man - the Canberra-based former Melbourne dentist has run 60 marathons all round the world and returned to Canada this week where he spent 20 years of his life.
A man who has run a super marathon of 84km in the vicinity of the North Pole and a marathon up the Great Wall of China with his daughter Serena.
And what did he think of the Aquathlon yesterday - consisting of a 750m swim and 4.6km run?
"Just a nice warm up for the Sprint Triathlon on Friday and the Standard Distance on Monday," said Lewis.
Like so many of today's heroes...there's no stopping him.
