No, I have done all my long rides (which are usually 3 to 4 hours) with a 2 x 10, although when the terrain starts going up, I am just using the small ring, leaving the big ring for any flat paths or road sections.
It is worth noting though, that I am in my 50's, and my son who is in his late 20's is much faster than me on similar kit... I am the tortoise and he is the hare.
