After a disappointing struggle and having to drop out of the Ironman European Championships in Frankfurt, Daniela Ryf will be looking for redemption at Challenge Roth this weekend at Roth, Bavaria in Germany.

In a very last-minute decision, reigning 29-year-old Ironman world champion of Switzerland has announced that she will compete at Challenge Roth. She’s using that hard-earned fitness to go after a new title—and perhaps a shot at the world record for fastest iron-distance race.

The announcement comes as a bit of a surprise because the race will not count toward Kona validation, which means she will have to compete in another Ironman in the coming weeks. Many expected to see Ryf on the start line of her home country’s Ironman Switzerland on July 24.

Ironman world champion Jan Fordeno joins the line-up

The addition of Ryf to the lineup increases the pre-race hype surrounding a potential record-breaking day. Fellow defending Ironman world champion Jan Frodeno (GER) is also on the start line and has not been shy about going after fellow German Andreas Raelert’s world record of 7:41:33, which was set on this Roth course in 2011.

Ryf’s challenge will be a bit tougher as she’ll attempt to beat out the 8:18:13 that four-time Ironman world champion Chrissie Wellington set in that same race in 2011.

As Wellington received news that Ryf would make the start, she Tweeted the following reaction: “So excited to watch @danielaryf line up at the best race in the world! Will world records tumble?! @ChallengeRoth1″
