A zero to a sixty, in a 7.5

I got bored so I decided to go cycling, by myself as usual.
Grabbed the roadie and set off on my usual 44km route.

I've got this new GPS programme installed on my phone and I decided to give it a shot.
When I got home, I uploaded the data onto my mac. It's quite cool as it maps out your route on Google Maps and if you transfer it to Google Earth, it lets you check your speed at almost any point of time.
Guess what? I hit 47.1km/h. YES, 47.1km/h!! And to add to that, that was a traffic light dash so I got from a standstill to 47.1km/h in a mere 8 seconds! (My gps better be accurate or it'll be damn embarrasing)
