Noticable, they are going crosswind

You are absolutely correct Harry -- in your link with that upwind race
for university students, held it Europe each year, there are no
specific requirement for crosswinds. The races are held head to head
between the competitors and they use whatever wind Mom Nature gives
them on race day.

The Blackbird directly downwind vehicle had no such flexibility. To
set the NALSA (and soon to by published Guiness) record, 18 recording
sensors were placed on the vehicle and the course and during the
record run it was kept within ~3degrees of the wind.
