Philipp at #3 and Spirig at #14 are among the 18 athletes in the top 25 of the PTO’s World Rankings who will be taking part.
“After my exciting Sub8 project in Dresden, I am now looking forward to tackle the second half of the year,” Spirig said.
“In my final year as an active triathlete, I am very excited to be competing at the PTO Canadian Open in Edmonton for the first time.”
Spirig’s inclusion sees an already-stellar field at the North American race, which has been dubbed the first ‘major’ of the PTO era, further strengthened as she is joined by seven other new names.
Sophie Watts (USA), Vittoria Lopes (BRA), Radka Kahlefeldt (CZE), Rach McBride (CAN), Grace Thek (AUS), Penny Slater (AUS) and India Lee (GBR) have all had their places confirmed on the start line.
Unfortunately one big name who is missing is top-ranked American Taylor Knibb, who withdrew on Wednesday night due to what she termed “a little injury”.
Joining the Norwegian duo – as well as home favourite Lionel Sanders and newly-crowned Challenge Roth champion Magnus Ditlev – are 11 additions.
They are Henri Schoeman (RSA), Matt McElroy (USA), Andre Lopes (USA/BRA), Kyle Buckingham (RSA), Max Neumann (AUS), Brent McMahon (CAN), Reinaldo Colucci (BRA), Steve McKenna (AUS), Pieter Heemeryck (BEL), Matt Sharpe (CAN) and Youri Keulen (NED).
