I think what we have here is a split between the "cyclists" and the "folk what ride bikes".
True, and nothing wrong with either in my book, it's the same with many past times, although would have to say their is a fair amount of irony that you are posting this on a bike forum, a place that you seem to hang out in a fair amount for someone that just rides a bike!
I like watching cycling on TV no matter what type it is, sometimes it's good to watch sometimes not, but what I don't get is why people feel the need to tell others it's boring? I find football immensely boring and frustrating to watch and can't understand why anyone would want to watch it but wouldn't go on a football forum and post how dull it is, as it's just my feelings.
As for the Olympic course, a rather done to death topic, I do side a bit with those who feel that it was a waste to build a new track, but then they built a new shooting range for the olympics, because the world class venue (not sure the name, sorry) was just a tiny, tiny bit far out and they wanted it to be as close to london as possible to promote the sport...Shooting not something that needs to be encouraged in london, maybe!?!
But as for it's technical content, I think as an XCO track it looks good, a bit man made but then a lot of terrain "we" ride these days is and don't have a massive problem with that. And in response to the it looks easy comments, 1, riding technical terrain after sprinting up the hill at full gas is very different to riding up the hill at a reasonable pace, stopping at the top to fiddle with saddle height and gloves e.c.t and then setting off. 2, xc race courses are not always the most fun to ride but conversely the best courses to ride don't always make great race courses. I remember years ago doing a race that was 90% single track and had some great technical elements, it was fun on the practice lap, in the race it was RUBBISH. You were constantly held up and then could never get enough speed to ride the technical sections and then when it started to rain it just got worse.
And in terms of comparing it to the commonwealth xc track xco have moved on a lot since then in terms of course design. Yes it's maybe not the most interesting thing to ride on a 140mm free ride bike but then I hardly think Glentress really warrants a bike like that for most of the time and no one seems to have an issue there. Plus if you live around the olympic xc course area, by the looks of it what are you doing with a bike like that!
In short it's a specific track built for a specific purpose, maybe not the best use of public money but then neither is the stupid opening ceremony, at least there will be something left after the olympic mtb race more than ticker tape and left over fireworks.
