What happens if you (ever) lap a bunch?
I am curious about this, but lets say we have a short-ish race course (like a circular track). Also, assume that there is some crazy strong rider, he/she attacks, goes all out, and suddenly finds himself about to lap the bunch. What happens then? Can that rider then merge back into the bunch and upon completion with the bunch, wins the race by default? Or must the rider continue on, not being able to shelter in the bunch ever or risk DQ?
