I've massively gotten into spinning in the last 6 months, getting quite good too. But I'm off to the desert again in January, and whilst the have the bikes and run the classes my work pattern won't give me the chance to go. So has anyone used one of the cd's you can get with the tracks already layed out on them? Or is there some software you can get to make your own? Or do you just make a playlist and a script and do it that way?
