How does difficulty level work?

[Shon_T]

I wouldn't use it like adjusting gears on a bike but more of a balance point for your fitness level and the Challenge you want.  At difficulty 1 you will move much faster with less pedaling, and at 10 the opposite. Depending on what I am doing I will adjust it, if for example I am trying to get a long ride done in a short time window I will drop it down to 1. Normally I leave it around 5.

Thanks for the response, That makes sense. 5 seems to work for me, and I think I get a fairly "real-world" type speed at that level. Of course....I'm screaming up hills much faster than I ever would in real life...but I'm often hitting long downhill portions much slower...
