A few days ago I was randomly flicking through the channels at home and came across the bobsleigh on Eurosport.  Now this is a sport that only comes into my conciseness when the Winter Olympics comes around and when ever Cool running is on TV.    However as my little boy was watching as well I kept it on a little longer and found myself getting hooked and encouraging each competitor to go faster that the previous competitor.   The more I watched this, the more I appreciated the technical side that the athletes have to take into account when travelling at high speeds.
