Follow the Leader in the Boulder Velodrome

Yelling to each other
to move left or right,
up or down, to go faster
or slower.
Pointing left or right,
elbows jutting out
or held close.
They flew by like
fighter jets sweeping
the sky, approaching
and falling away in the
next moment.
Grouped in formation,
splitting and regrouping.
An orange one, a blue one
a green one, one in faded
blue jeans, a messenger
from heaven extolling
the joy of play.
