Well, the ride took about 3 min 15 s, which at 2 km yields and average speed of
37 km/h. That is probably not far off as an average, although I'm sure he was
going a lot faster than that for much of the course. I would estimate an
average grade of around 5 to 6%, so 2 km at say 6% does give 120 m.
And that of course illustrates the simplicity of working in metric units - a
rather more difficult calculation in imperial/USC.

Lets have some fun and take a look at this video. Metric connection: guess
how long the course is, and maybe the elevation loss (their website doesn't
say). My estimate is 2 km and 120 m. Anyone else?
