Remember when the Iron Cowboy (James Lawrence) added one day to his 100 straight full-distance efforts to seemingly keep his amazing performance safe for a while? Last year Great Britain’s Sean Conway added four more days to Lawrence’s record when he completed 105 full-distance efforts in a row.

C’mon … 100 full-distances in a row isn’t enough! The Iron Cowboy does one more

Now the man who broke Conway’s record for the longest triathlon (a 4,200 mile/ 6,759 km journey around the coast of Britain), Jonas Deichmann (pictured above while running in Mexico), is looking to take another of his records. Deichmann is planning to complete 120 long-distance triathlons in 120 days over the Challenge Roth course. That’s four months of completing the equivalent of an Ironman-distance race every day.

Deichmann plans to start his effort on May 9, 2024 and complete it on Sept. 9. He’ll celebrate the halfway point of his record attempt by joining the rest of the field 3,500 individual competitors on July 7 for Challenge Roth.

Deichmann has set a number of cycling world records including the fastest crossing of Eurasia (and set a new record for crossing Europe at the same time), rode, unsupported from Alaska to Argentina in 97 days and from Capenorth, Norway to Cape Town, South Africa in 72 days, seven hours and 27 minutes, breaking the previous record by 30 days. He broke Conway’s longest triathlon record thanks to a 429-day journey around the world that was the equivalent of 120 long-distance triathlons – 456 km of swimming, 21,600 km of cycling and 5,064 km of running.

Since the Challenge Roth swim course in the Main-Danube Canal is closed other than race day, Deichmann will complete each day’s 3.8 km swim in the Rothsee, a local lake. He’ll then complete a 180 km bike and a 42.2 km run on the original Challenge Roth course.

“I will always be an adventurer, but I want to find out what is really possible and where better to do that than at the legendary Challenge Roth,” Deichmann said.

The German will be raising money for the Roth youth fire brigade and the Laureus Sport for Good foundation. As with his long-distance triathlon record, a book and documentary is planned to commemorate the record attempt.
