The 'optimal' is of course a question of ambition - and whether you want to be riding optimally at all. But let's be honest: On the bike you (almost) always want to ride faster, further or higher. It's the rush of speed on a Road bike. Or the fascination of another go on the trail.
And how do you approach this in practice? "In the beginning, just ride a power meter. In order to get a feeling for the numbers, the legs performance in different situations and especially after how much time", is Björn's tip. "When I start at 200 watts, it doesn't feel like anything. But after two, two and a half hours I notice: 'Oops, that's exhausting!'". In the peloton of a Tour de France or a Transalp Challenge, the professionals make use of exactly this information: measured by a power meter, the riders use exactly the power they can over a long time without losing it. "If I know that my ideal continuous output, we call it threshold output, is 350 watts, for example, then I go up the mountain with 350 watts," the training expert explains the procedure. In this way it could be ensured that the increase could be achieved or that it could be managed within a certain period of time.
