Saint-Sernin-sur-Rance to Albi

This was a pretty easy ride on pretty much all zero and low traffic scenic roads, with the only exception being when approaching Albi. 

Note that the two spikes in the profile near the end of the ride should be ignored. They're due to going through flat tunnels. As such, the climbing is probably around 480M rather than 630M.

As the tunnels are narrow, though with some lighting, it's best to have both a headlight and taillight for these two tunnels.
