The climbing started at 9am, so having a clear "you can go here and watch" would have been an incentive to be up significantly earlier than the times I have otherwise been up at.
Instead, I ended up going to sleep stupidly late, and crawled out of bed around ten past midday.
Still, turns out it is being covered by the BBC - hidden behind a beach volleyball thumbnail and title, there's a 915 minute long Olympics morning episode, and I was able to jump to the 9am mark and, after a really fucking stupid dog puppet thing, there seems to be the full coverage of men's qualifying bouldering.
Hopefully this means they'll be showing all of it, because I don't know if it's something James can help with.
