MVDP and Trentin talked about it before the race and concluded it was a bit like cyclocross, a million corners, slippery when wet and filthy. I think it was extra filthy because there's a lot of traffic using those city roads and there's been a long dry period before the race.
I can't believe how filthy the roads were. It's not a great circuit is it? You'd think they'd have worked that out from the Commonwealth games.
