25-hour Indoor Ride: Matthias Heil | ROUVY Unchained #4

Explore the world of ultra-endurance indoor cycling with ROUVY rider Matthias Heil, who shares his journey of spending 25 hours on the trainer.

“It started at my parents’ house … they had this ancient ‘dumb’ trainer – the kind with a belt and a screw. I hated it. No resistance, no feedback … but then I tried ROUVY.”
“The real routes. Many I’ve ridden in real life, especially in the Alps. You recognize them. And the realism is surprisingly immersive – even though you know you’re in a garage.”
“Online races start insanely fast. I like hammering it from the word go. I’ll lead for a few seconds, then take a screenshot of the empty road ahead. Then I sit up.”
“Like everything: it escalates. One day I had an incredible tailwind and ended up riding 210 kilometres. For years I thought I’d never beat that.”
“I did over 600 km – around 624, I think. And the hilarious part? Someone beat me by 0.1 miles. About 160 metres. The length of my garden, basically. I wasn’t gutted – I was amused.”
“I’m very low-tech. For longer rides: Rice pudding with jam stirred in, because it’s easy to slurp and doesn’t require chewing. And for the really long rides: my wife makes the best mushroom risotto in the universe.”
“Motivation isn’t really a problem for me. Indoors is much easier than outdoors because everything is right there – food, drinks, showers, no punctures, no weather.”
“People say indoors is psychologically harder because you can stop anytime, but for me it doesn’t work like that. I’m doing the ride, so I’m doing the ride.”
“Long rides change how you experience suffering. In a one-hour race, if you feel awful, the whole race is ruined. In a long ride, a terrible two-hour patch is just part of the journey.”
“Build it up step by step. You don’t wake up one day and ride 600 kilometres. You start with one-hour loops. Then 40 kilometres. Then 60. Then 100. It grows.”
“Nobody knows why it works. It’s so fast that it probably isn’t physiological. My best theory is that it shocks your system because it’s so disgusting. But it works for me. Try it!”
