After driving cross country in 4 days I can't imagine doing it that quick on a bike. Those Iron Butt guys are truly hardcore as the record from Alaska to Florida was a lot shorter than what I could do driving cross-country with a co-driver. As soon as I can find a stupid job I'm riding out to Washington state and taking more time than 4 days to do it. CO is one stupid long day of riding and 1 long day of riding. It would be a beautiful ride if it wasn't for kansas, illinois and iowa
