After the World Championship race in Kona at mid-October, I have updated the Top 10 Rankings. The previous update has been in mid-July, shortly after IM Germany and Challenge Roth.
TOP 10 Rated Ironman Distance Athletes
TOP 10 Rated Male Athletes
Kona has brought a number of changes to the Top 10 rankings. First of all, Kona winner Patrick Lange is now my #1 ranked athlete. (He was previously unranked, Kona is only his third full distance Ironman race.) Even with a slightly slower rating, Sebastian stays in #2. Jan Frodeno (with his slower Kona finish) has dropped back to #3. Patrik Nilsson stays in #4 but was able to leap ahead of Andi Boecherer who wasn’t able to race in Kona. (Andi is the only athlete in the Top 10 Rating who hasn’t been able to race in Kona.)
David McNamee (third in Kona) is now #6, Lionel Sanders (second in Kona) is in #7. Ben Hoffman is also new in my Top 10 after his Kona race. Andy Potts (now #9) and Bart Aernouts (now #10) have dropped slightly back from the mid-July rankings.
Tim Don (was #7, he dropped back to #11 without a change in his rating after he couldn’t start in Kona), Tim O’Donnell (was #8), Nils Frommhold (was #9) and Brent McMahon (was #10) have dropped out of the Top 10.

TOP 10 Rated Female Athletes
Of course Daniela continues to be my top ranked female – with her win in Kona she was still able to further improve her already great rating. With Mirinda Carfrae (currently not ranked after more than one year without a race – she has just given birth to daughter Isabell and is likely to return to racing in 2018) and Rachel Joyce dropping out of the Top 10, the new #2 female is Kaisa Sali followed by Heather Jackson.
Lucy Charles enters the Top 10 in #4, followed by Meredith Kessler (another soon-to-be mom), Susie Cheetham and Yvonne Van Vlerken. Mel Hauschildt has dropped back to #10, she was overtaken by her fellow Aussies Carrie Lester (now #8) and Sarah Crowley (#9).
