Apologies if it has been mentioned elsewhere, but you can follow Graeme's progress at the human-powered land speed record in Battle Mountain, Nevada here - http://www.humansinvent.com/#!/tags/cycling/
The official WHPSC page is here - http://www.recumbents.com/wisil/whpsc2013/speedchallenge.htm
They're pretty slow with the updates but there is lots of good geekery to be found on the site.
I also found this via their forums - http://new.livestream.com/accounts/5346183/events/2388331 they're broadcasting live feeds from each session and have some earlier videos available to watch. All fairly amateurish
And the man himself has been posting updates on his site - http://obree.com/obree-news.html
A piece for BBC Technology by Richard Moore is at http://www.bbc.co.uk/news/technology-24015622 and I think the Daily Record has someone out there.
Latest on Grame's HPV record attempt on the Cycling Weekly blog:
Prone record is his. It might not be the record he originally wanted but good on yer Graeme:http://www.dailyrecord.co.uk/sport/other-sports/cycling/flying-scotsman-...

Only 3 lots of runs left and riders are having to put their names into lucky dip draws to get places because of the weather delays
