There is riding and riding. I've met many people always "riding all day" when they were in fact looking at obstacles,
discussing, joking around, drinking, eating, sitting on their bike ... I mean look at the videos: 80% of the riders in the
background are not seen riding.
Counting the time one is engaged on an obstacle with both feet on the bike, I would reckon the average rider does
7 to 10 hours a week. This intensity normally results in constant aches, to which one can get used to with the right
mindset of wanting to fight and build something.
