The Aussie pair of Craig Alexander and Mirinda Carfrae are back to defend their Ironman 70.3 Muskoka titles on Sunday.
Muskoka has proven to be a great Kona tune up for Alexander, as he has won in Hawaii after both of his wins in 2008 and 2009. It was almost as magical for Carfrae, as she finished second in her Kona debut after winning here last year.
South Africa’s Raynard Tissink is making the trip to Canada for his final tune up race before the Ironman World Championships, and Kiwi Joanna Lawn is doing the same.
Ironman.com will have live coverage.
