Now that I've been a MTB fan for a few years, I'm trying to figure out how the pro's manage their income. I've been following Jason English & Ed McDonald on Strava. They put in a HUGE number of km's every week. I'm intriged to find out how they manage to get so much training time - money for all the food they must consume! - drive train replacements - general income for living etc.

I'm not asking for exact dollar amounts at all. I'm sure that sponsors & prize money take care of some of the costs.
