Deep dive: The new world record in full-distance triathlon

The barrier of what is humanly possible has just been pushed forward with Sam Laidlow’s new world record over the full triathlon distance. 

In this deep dive, we take a closer look at many of the considerations the new record holder had ahead of his groundbreaking performance at Challenge Roth.

You do not complete a full-distance triathlon in 7:21:04 without unconditional dedication. That applies to training, preparation, and development. Sam Laidlow’s mission from the start of the season was not necessarily to break a world record. It was rather to be as well prepared as possible for Challenge Roth, which was the first major goal of the year.

We have previously been a driving force in Project Sub-4, where we together with Sam pushed new boundaries for bike splits when he became the first athlete ever to ride under four hours in Hawaii. Even so, we were extremely proud and honoured that Sam chose our Performance Program approach as the path towards his new world record.

This approach is carried out in close coordination with key partners who also want Sam to become the fastest version of himself. Already in February, preparations began with a visit from Canyon, who brought a version of their new and optimized Speedmax for Sam. The aim was not only to test the new frame against the existing one, but also to ensure that Sam was in the best possible position across every choice that could be made on the frame and cockpit.

Together with Canyon, we created a strong plan that also built on the work we had carried out in collaboration with Aalborg University, where we investigated biomechanics in interaction with aerodynamic performance. Based on this, we defined a range of possibilities for testing the position, which Canyon then prepared for our test sessions. Together with Sam and Canyon, we therefore had the opportunity to see what worked and what did not.

With more than 139 days until race day, we were confident that Sam was in the best possible position on the bike. And far faster than we had expected. Both we and Canyon were surprised that it was possible to find such a significant improvement in an athlete who was already one of the fastest on the bike. We did build on many of the experiences and expectations we already had, but we were still surprised by how well our assumptions worked in practice.

After three full test days in the wind tunnel, it was clear that Sam was in a better place than ever before. The position was the fastest we had ever tested. The bottles and hydration systems worked in harmony with it. At the same time, we ran an extensive sweep of materials to ensure that the suit worked together with the changes that had been made, while also gaining the necessary knowledge to improve it even further.

After the first visit, Sam returned home and brought some of the changes with him to the first race of the season, IRONMAN 70.3 Valencia, where he won a convincing victory. And knowing that several improvements had still not yet been put into action, there was plenty of optimism afterwards.

At the end of April, Sam once again returned to Svenstrup. In the meantime, Canyon had prepared a new version of the new bike and cockpit, implementing the things we had found. Ekoi had also joined the dialogue and developed a new prototype helmet with a series of visors. Everything was tested in combination with Laidlow’s new position and new suit, and here we also found strong improvements.

With all the major improvements in place, we had the time to go even deeper into the details. With 69 days until Roth, Sam knew that Canyon had given him more speed - and that Ekoi had done the same. That also allowed us to test a wide range of possibilities for improving the existing suit and creating a special Roth suit.

We had already started that work after the February visit. Shortly afterwards, we began preparing a wide range of different suit solutions designed to work well with the new position and the different options that could be tested in combination with the new helmet. We tested and verified a wide range of solutions in interaction with both the helmet and the position. We also tested a wide range of solutions for the lower leg, so Sam would have the best possible basis for choosing the solution that was both the fastest and aligned with the planned race strategy.

Sam Laidlow tried several different helmet combinations from EKOI. 

Shortly after the visit, Sam won again. This time at IRONMAN Lanzarote, and once again without using all the aces. That has been a carefully considered decision, made in ongoing dialogue with Sam. Certain elements have been implemented directly to provide an advantage in the build-up races, while others have been held back in order to create the major advantage at a key goal such as Roth. That also meant that Roth was the first race where we would see the full effect of our work come to life. We therefore followed the race with biting nails and huge excitement. In a way, it was also a defining day for our role as the coordinating force in our Performance Program.

We believed he could win. We knew he had the level. Even so, we were surprised by the way he did it. It was inspiring to see him put everything on the line. To believe in his plan and be uncompromising from start to finish. To dominate Europe’s biggest triathlon event in that way.

We are therefore looking forward to once again welcoming Sam back to HQ in July. Because even though he has already spent five full days here and gone through 119 different configurations, we know that we still have more up our sleeve before the World Championship in Hawaii this autumn.
