Also, highlights can only be up to 50% of the coverage... well as long as Channel 4 are happy to dedicate a chunk of time for the program as a whole then that won't be a problem. 1 hour build up, 1.5 hours of race, 30 minutes of post race analysis... sounds good to me.
You're more optimistic than I am. They're gonna show the bare minimum. No way will we get an hour build up for highlights.
