What he was describing sounded more like a Ranking/Testing situation. In that case 4hrs is nothing, but i wouldnt call that training by anymeans. That would be the reason you are training for.

Same would go for a marathon runner, no one in thier right mind goes out and trains for a marathon by trying to run the full distance 3 or 4 times a week. Just doesnt happen.
