Check with the user "merlinextraligh".
IIRC, he rode the USA Pro Cycling Challenge with Carmichael's "team",
i.e. they rode each days course prior to the actual race.

As for Carmichael and LA; Carmichael was just LA's "beard".
i.e. a mutually beneficial arrangement where LA claimed to be getting coaching from a legitimate source,
while Carmichael got his name associated with the most successful American pro cyclist ever.
