I used to train on the old K37/10 Hollywood bypass (long since defunct due to traffic lights). If three HGVs passed in quick succession, I could be doing 30mph up a slight rise with very little effort. There is a reason that open events on such courses sell out at the drop of a hat - they offer a far higher chance of a PB (or sudden messy death) than a quiet course.
