I thought the same thing as Mike when I read your topictitle. We get to play hockey, soccer, etc generally just having fun with the whole group as warming up for about 2 or 3 weeks and then some longer work. After these two or three weeks we start the preparation for next season.
Of course track never ends. Thats why it is interesting to see what kind of alternative work people do for the few days after the season is over or if they continue practicing and never take time off.
