So i went back and looked at the video again and did some analysis…at :04" the crash has begun and the rider w/ a light blue jersey is starting to fall over to the right into the grass. Just after that (still showing :04" on the timeline, though…which shows how fast this stuff can happen), two riders are in the grass and the rider in front of you is heading towards them (also probably radar-locked).
At :05", the rider in front of you is sideways and half into the grass…but the lane to the left is wide open. That was probably your window to avoid the crash (actually a bit before it, but it is most visible at this time). Plus, you need to think about the “momentum of the crash”…IOW, which way will the wreckage travel based on the direction of the race / course. Easiest example to understand is a crash in a corner…the momentum of the crash will be towards the outside of the turn and your “out” is usually to the inside as a result.
Again, this is a skill / experience thing…it is really hard to not focus on a crash when it happens right in front of you. It is totally natural to do that. Someone above mentioned “knowing where your out is”…this is a critical racing skill. It is a constant observational skill that gets enhanced the more you race.
In the case of this crash, your “out” was always gonna be to your left…you were up against the right edge and the momentum of the crash was going to the right. The only option you had to avoid the crash was to go left.
But as most of us have said, this was primarily wrong place, wrong time. You definitely didn’t do anything wrong, but in the future, you can perhaps do some things “better” (if that makes sense).
Did you end up getting banged up at all in the crash? Bike OK?
