If they are pictures from this year, then the course was flat and uphill. How you can count the front and rear teeth in those pictures is beyond me though.
Since both of the riders are not just joe schmos on their respective teams, its a very high probability that their position was setup in a wind tunnel to maximize their speed over the duration of the TT, which this year are all very short.
