Kudos to GC for the proper use of QED.
Two years ago I got taken out by a Polish national champion. He was at the front end of the race but in way over his head with his ability to handle the one technical turn on the course and the speeds going through the corners. He kept opening up gaps. When I finally had a chance to get around him on the right, riders were passing him on the left at the same time. He swerves hard right into me and hits the brakes. There's a huge tree on my right so I held my line, we hook bars, ride uncontrollably onto the grass, and crash. Prior success doesn't always indicate current skill.
