I feel sorry for you there haha.
I remember we always had to do the 1500m... If you didn't look like you were trying, then you had to do it at lunchtime in front of everyone...
Cross country was always a good laugh. We had to do 4 laps of our school, and it took the really fast people 30 minutes to do it.. It was so horrible.
BUT every time you did a lap you got given a coloured straw, so teachers knew which lap you were on, and one year (Year 9) it snowed... So we all - I say all, there was about 15 of us out of the 70 people running it - decided to do two laps so we had around 30 straws, and we went up to the top corner of the field which you have to run around, but there were no PE teachers up there to motivate you, and none of them could see up there from where they were standing.
To cut a long story short, we built a massive snow penis and stuck all our straws in it.. It was hilarious at the time.
Looking back on it, it was probably one of the most immature things I have ever done.
