When our fastest long distance athletes toe the starting line in Tokyo this summer, they’ll be wearing the Cloudboom Echo. It’s our lightest, fastest marathon shoe and it’s proven to perform better than any shoe we’ve ever made.

The Cloudboom and Cloudflash go together like thunder and lightning. One’s made for longer distances and the other for shorter, speedier bursts. But they share the same high-velocity DNA and, as you might have noticed, a very similar look.

Go on, open up your pack and tell us all about the items you can’t be without. Okay, we’ll go first. We asked On athletes and community members to give us an inside look into their essential everyday items.

With so many marathons taking place each year, it can be tricky to know which to choose or when to run. Fall might be the ideal time. The weather is usually a little milder and conditions more favorable for running. However, we can’t promise this is true for every marathon on this list…

It's the fast way to build strength and boost endurance. If you're looking to take your running to the next level, it's time to try intervals.

Every On shoe feels unique. And that’s no accident. CloudTec® technology visibly contributes to the sensation of running on clouds, but it never works alone. Its partner for propulsion is the Speedboard® – the secret to converting soft landings into explosive take-offs for the ultimate ride.

A dedicated racing shoe separates the casual runner from someone looking to take things a step further, faster. But despite their promise of pace, racing flats simply aren’t for everyone. Let’s take a look at whether a racing shoe could help make 2018 your fastest year yet.

Ahead of the Zurich Ironman, one of On’s hometown events, we sat down with Swiss champion Ruedi Wild to ask how he feels now competing for a podium place in the local race he watched growing up.
