Picks up where part 3 ends. Fast short descent into the right turn (east) on D-38 toward Bronson. The pace was pretty high for a time with the tailwind. Another right turn (south) and the pace ramps up on the flat and into the first incline that sweeps east up into the beginning of roller coaster hills. Keir still near the front. Does a nice job regaining some lost positions on the descent.
