Wierd drafting trick I've used, on long straights:
Basically, if the pack is strung out pretty long, and it's single file or near it at the head of the group, I move to the outside, put in a quick burst, and then move up to the front or near the front hugging the line as tight as possible. You almost get sucked along, even though you aren't in the draft. A lot easier than being completely in the wind, and it might only work because I'm small. Not sure how it works, to be honest, and this wasn't the best description.
