I am sure people have had worse coaches than me, but my high school coach sucked! He weighed about 375, and always had a cigar in his mouth. His favorite drill was to make us run backwards on our messed up dirt trails. We had many falls and twisted ankles. We would run the bleachers, but only one leg at a time, maybe this is okay for hurdlers, but not for cross country.
He would yell at us for drinking before practice and there was no water during practice.
And his worst advice he used to give us was "After the race, try to pass other runners in the chutes". Of course no one listened to him on that, if someone tried to pass me in the chutes I would deck him.
