Magnus Ditlev shares all the insights from his Ironman World Record time in Florida

MAS Technology: How Fusion Built a Zonal Aerodynamic System Launched at Kona 2026 Watch the full episode on YouTube: https://youtu.be/XcZWEwV-4LA?si=ZC-YR65RxDXrAiZ7 Tri-Oraklet talks with Johannes and Sebastian from the Tempo_Tech Windtunnel and Fusion about MAS (Multi-directional Air Shaped) technology, launched at the Ironman World Championship in Kona. They cover how a 3D surface structure woven into fabric moves beyond stripes and ribs, and how it was tested in the tunnel and in the field. Key topics Origins: Development began around the 2022 Ironman World Championships with wind tunnel fabric mapping. Fusion's in-house Tempo wind tunnel has run for two years. Beyond stripes: Earlier suits relied on stripes or ribs. MAS uses a 3D surface structure that works across a wider speed bracket and more angles of attack. Drag2Zero and Simon Smart: The structure was originally devised by Drag2Zero and Simon Smart as a 3D-printed silicone structure. Fusion wove it into fabric using a super fine construction technique and full supply chain control. Normann Stadler: The Kona winner and 2006 Ironman record holder tested in the tunnel before racing the age-group Ironman in a Fusion suit. Zonal design: Different fabrics are used on the sleeves, shoulders, back and side panels, with a smooth front. Drag curve: The effect starts around 30 km/h and is fully present around 45 km/h. Back zipper and ice pocket: The new ice pocket has neck channels. Magnus Ditlev used it in Kona. Testing: Seven Kona athletes spent up to almost 300 hours in the tunnel. Final testing took place in France with Sam Laidlow. Field testing used an aerosensor (pitot tube) to calculate CdA. Protection: The technology is patent-protected, with exclusive fabric manufacturing. It will be applied beyond triathlon. Three key takeaways (from Johannes) Multidirectional versatility across the speed range and angles of attack. The zonal approach. A holistic rider-bike system view that includes swimming, running and cooling with the ice pocket.

Julie Søe Mikkelsen fra Aarhus 1900 TRI, blev i tiden 10.37.00 hurtigste danske kvinde til Ironman Hawaii 2026. Ud over at være politibetjent i Aarhus, har Julie en sportslig baggrund indenfor Cross-fit på konkurrence-plan, men begyndte at træne til Ironman i 2023 efter en alvorlig knæskade.

Mikkel Olsen, tidl. ungdomslandsholdsrytter, blev hurtigste dansker til at gennemføre Ironman Hawaii 2026 (8:52:45). Det mest brutale race i mands minde, hvor forhåndsfavoritterne knækkede på stribe og ingen af de danske professionelle nåede målstregen.

Frederik Wester er netop hjemvendt fra Ironman Maryland, hvor et alvorligt styrt fik de lokale myndigheder til at neutralisere konkurrencen, så en lægehelikopter kunne lande midt på cykelruten. Herefter fulgte et sandt kaos i forsøget på at finde en sportsligt fair afgørelse og kåre den "rigtige" vinder.

Thor Bendix Madsen var kun 1 min fra EM titlen, da han i tiden 7:38:00 krydsede målstregen i Almere, Holland! Karrierens hurtigste ironman-konkurrence med ca. 10 min og masser af drama undervejs!

Anastacia Damm var et stort ungdomstalent inden for både løb og triatlon, men efter mange års dedikation til OL kval. og sprint triatlon, forsvandt gnisten pludselig. Glæden vendte dog hurtigt tilbage, efter 1/2 jernmands debut (Alssundman), hvor hun blev øjeblikkeligt hooked! I 2026 har Anastacia fået sit helt store gennembrud med både 70.3 EM Bronze i Sverige og en 4. plads i PRO serien (Zell-am-See).

Med fantomtiden 8:14:47 i Ironman Tallinn, blev Viktor Bertin den yngste nogensinde (19 år og 71 dage) , til at køre sub 8:15 på den fulde Ironman distance. PÅ verdensplan har kun 3 atleter i AG 18-24 kørt hurtigere, dog alle noget ældre på konkurrence dagen (2-5 år) end den danske teenage sensation var, da han krydsede målstregen i Tallinn søndag d. 22 August.

Maja Stage Nielsen - én af dansk triatlons mest dekorerede atleter gennem tiden - stopper karrieren efter mere end 10 år som professionel og + 20 podieplaceringer fordelt på Ironman og 70.3 distancen.

Mathias Amtoft (26) - som netop har været med det danske landshold til EM i Mixed Relay - fortæller i denne episode om sin utraditionelle vej til landsholdet og viljen til at blive elite-triatlet, trods en baggrund i holdsport frem for atletik eller konkurrence-svømning.
