German adventurer and extreme endurance athlete Jonas Deichmann has completed his 106th full-distance triathlon in as many days to set a new world record.

Known as the ‘German Forrest Gump’, 37-year-old Deichmann holds multiple world records in cycling and endurance events.

He has a strong swim / bike / run history too, with his ‘Triathlon 360’ in 2020 taking him around the world and the equivalent of 120 full-distance races.

And 120 is the magic number for this latest charity challenge which has seen him complete 3.8km of swimming, 180km of cycling and 42km of running every day around the famous Challenge Roth course in Bavaria, Germany.

Diechmann overtakes Conway

He started on 9th May and the 106th on 22nd August was a notable milestone as it saw him surpass the previous record of 105 set by fellow adventurer Sean Conway of Britain.

But his ultimate target is to reach 120 on 5th September.

The halfway mark – or what he called a “half-time highlight” – came on the day of Challenge Roth this year in early July, which was also notable for world record performances in terms of the quickest-ever full distance times for Anne Haug and Magnus Ditlev.

‘Project not over’ yet

Writing on his Instagram page, Deichmann said: “🌟 WORLD RECORD 🌟. Today I finished my 106th long-distance triathlon in a row @challengeroth.

“For 106 days, I executed an Ironman-distance triathlon every day. With that I am the alone-standing world-record holder.

“But with that, my project is not over. I will toe the start-line for 14 more days to complete #challenge120

“A huge thank you to the local community, who supported me outstandingly, each and every day.

“Thank you to team @challengeroth for hosting this world record attempt and organizing the surroundings.

“And finally a huge thanks to my family and my team, who made this world record possible.

“Today it‘s time to celebrate, tomorrow it’s focus on the next 14 long-distances.”
