As was discussed, crashing is just part of their sport. Get up, get back on, ride and work out later if you were hurt. Obviously unless you were too hurt to get back on. In many cases it would be frustrating as it would break rhythm and often cost placing in the bunch. But they go and go hard to :get back on” the bunch and just carry on.
If it was continuous and it was an at fault loss of control or focus that repeatedly occured to oneself, then a lack of confidence that you had the full skills might undermine self confidence, but if you know cyclists, they’re usually a “cocky” bunch.
