I love my ciclosport except for the fact that it zeroes out time and distance (but at least not altitude) after 10 hours. It's like any number greater than 9:59:59 won't fit on the screen. I'm not doing any doubles under 10 hours any time soon! It would sure be nice to not have to watch it like crazy for the last 15 minutes and then miss it right when it zeros out so I don't have an accurate mileage counter...
