I watched the streamed replay of the race and it seemed to contain the entire thing.
I did the same this evening..initially I just watched the first 30min under the "preview", and then it asked for my cable provider...I clicked on Verizon and that was it...no login etc...watched the entire race. I assume it recognizes my IP and verified that I am in fact a verizon customer. But the actual race footage was pretty good, I thought. At least in terms of visual coverage...the actual audio mix was a little off---announcers were somewhat muted compared to the background noise-- but I was happy to be able to see the race.
