Speaking as a runner, when someone says the track is fast, they mean one of two things:
1) Fast times have ensued or are likely to ensue based on the talent and competition.
2) The track is well built, possibly including slightly banked turns, and with the case of a track like the one used in the Bird's Nest, there is no wind.
