...it's getting back up.
Today, on a training ride, one of my teammates went down pretty hard on the mountain bike section (though not as hard as the guy in the picture) - she's nursing some pretty decent wounds on her elbows tonight, along with her fair share of bumps and bruises.
But she finished the ride.
That being said, my wife had to tell her to get back on - because, having gone through a similar fall herself, she knew the importance of getting back in that "saddle". You see, the biggest obstacle you face after a fall is the fear that you feel on every turn and drop, and the frustration that builds with every little fall afterwards. But all of that pales in comparison to the feeling of failure that accompanies not even trying.
It's all right to be afraid - it's not all right to quit.
