2. You can’t take the time to savor the experience of being out in the mountains, on your bike.
Once that gun goes off, it’s top-speed to the bitter end. What if you round a bend to see the most fantastically-beautiful mountain view you’ve ever seen in your life? Nope, can’t stop for a photo, that’d take too much time. Is it 100 degrees and you’re riding past a crashing waterfall with an inviting pool of cool, refreshing water? No time for a swim, the clock is ticking.
Maybe it’s different for you, but personally I ride my bike in the mountains for the beauty of it all, for the experience, and to escape the pressures of daily life. But if you’re racing, the pressure is on the entire time.
