I just realised, that "2000m of descending" doesn't really mean much, so, if you were wondering what the hell 2000m of descending means, well Snowdon, the highest mountain in Wales, is 1085m high.
Ben Nevis is 1344m, and Scafell Pike, the highest peak in England, a mere 977m.
So, 2000m of descending is like riding down Snowdon. Twice. In 40 minutes.
Do you see?
