Scream if you wanna go faster!!

A visit to the £113m VaVaVoom Velodrome this morning fairly got the adrenalin pumping!
First look put me in mind of the funfair wall of death, eeekkk!!
When the coach encouraged us to adopt the mountain bike saying flat out or fall off, I thought of the skiers motto - brakes are your enemy, speed is your friend. This could be addictive.
Mmm, now there's a question............where are the brakes on these babies??!!
