The line up for Challenge Roth on 17 July line up to include World Champion Daniela Ryf from Switzerland, who is number 10 in our top 10 female triathletes of all time. She will join fellow world champion Jan Frodeno, who is aiming to beat the iron-distance world record at Roth. Roth will be the only race outside of the Ironman World Championships at Kona, Hawaii where both current world champions will race.


 Ryf entered Roth after being unable to finish Ironman Frankfurt due to health reasons.

 “After I unfortunately couldn’t finish the race in Frankfurt for reasons already known, we changed our plan. I’m really looking forward to being on the Roth start line and being able to experience the legendary atmosphere of this race!”
