This is 
the first race on this course. All time predictions are based on a “neutral” course.
Between 2010 and 2012 there was an Ironman Regensburg, now the race is organized by a local team around professional athlete (and new mom) Sonja Tajsich under the Challenge banner. There are some similarities to the old course, but it has been redesigned to ensure local support for the event.
Prize Money
Challenge Regensburg has a total prize purse of 38.000 EUR.

Winning Odds
Male Race Participants
The main competition will be between two athletes that have won Challenge races before: Fredrik has won in Atlantic City and Taiwan, Chris has won Challenge Denmark in 2015 and 2016. Chris McCormack is on the start list, but his last finish over the IM distance is more than three years ago, it’s unlikely that he’ll be able to play a factor. Jan Raphael is a steady German athlete he’ll want to play a bigger factor than he was able in the star-studded field at Challenge Roth. Another interesting athlete is Malet Bruns – he was the fastest agegrouper in Kona last year and is racing as a Pro this season:
- Fredrik Croneborg: 41% (1-1)
- Chris Fischer: 38% (2-1)
- Chris McCormack: 9% (10-1)
- Jan Raphael: 8% (12-1)
Female Race Participants
Veteran Erika Csomor is the top-ranked female, but Carolin Lehrieder and Kathrin Walter would like to keep the title in Germany.
- Erika Csomor: 50% (1-1)
- Carolin Lehrieder: 29% (2-1)
- Kathrin Walther: 14% (6-1)
