A 15-kilo gravel bike from eBay. Flat pedals. Mudguards. At the
start of a fast group ride in Girona, the others smiled. 80
kilometres later, they were the ones asking questions.

How is that possible? The answer goes back to 2015. Six months
before Rio, every test said Jonas was in the best shape of his
life. Then he sat down on the ergometer, and his body shut down.
Three months later he rowed 98 % of his personal best on less
than half the training. Somewhere in between, he found the lever
he had missed.

In this solo episode Jonas opens up the model behind it:
Performance = Outside × Inside. Why one group of swimmers got 8 %
faster and the other almost 10 % slower on the exact same
training. What six hours of sleep can cost you in an Ironman. And
which athlete type you turn into on a bad day.

So, where are you losing performance?
