Karting

There was a go karting event that was organised by some people at work today so there were about 50 of us competing in teams of 4.
After the qualifying the team I was in had the quickest average time.
In the final race all was going well and in the last few minutes I managed to overtake the person I had been chasing for several laps. As I was half way around the next corner I was nudged from behind which turned the kart into the tyres and I was stuck for about 30 seconds.
That put up the my average lap time and we ended up 4th, what's worse is that it was one of my own team mates who nudged me.
Still it was good fun.
