Oh, this is what (I think) happens:

start_game runs:  everyone [clickon]

each clickon runs the instruction of each turtle: start_run random 70

start_run runs: forever [check ...]
(this happens for each horse, so we have 3 check processes
running simultaneously!)

finally, when "check" detects touching?
check runs: everyone [clickoff]

so:

by running "everyone [clickoff]", the check procedure effectively
kills itself before reaching the winner instruction.

Moral of the story: 
check shouldn't be called from within a turtle instruction.
