I think the record is about 51 hours non-stop. I have to say, having ridden a very similar route, that is absolutely mind-blowing! When I rode the distance it took me about 70 hours of cycling over 14 days!
I just cannot imagine how hard that was. Well I can get an idea, judging by the look on James Cracknell's face going up Shap Fell. That's not what I would describe, as the Telegraph did, as "looking composed and ready for more as they reached the end of the half hour slog".
That is the look of two people who would like to lie down in a dark room for about a year.
It's a terrible shame they weren't able to finish. They were forced to stop before Edinburgh after medical advisors warned of long-term damage to Romero's knees if they continued.
I must go and take a look at their training regime.
It's also a shame that the story wasn't reported as widely as it deserved. Speaking of which, Mark Beaumont has reached Salt Lake City on his bid to cycle the Americas from Alaska to Argentina. The man is amazing, if possibly certifiable...
