Sorry djb. Trackies is people who ride track, as in velodromes (usually indoor). We seem to have a very strong track tradition for a country with such beautiful weather, as the Comm Games showed. And I was surprised talking to the Canadians that they have few international standard velodromes. Melbourne has two; one is only available for special events but anyone can access the other one and local clubs race there every week. Plus half a dozen shallower outdoor ones.
