Relation between MTB and Bent

In my MTB after a 30 km ride I am tired and my leg is hurting,
what would be the distance in a Under Control Bent that I will have to ride
to get the same feelings? I figured 40 km as air drag is 30% less in a UCB,
am I right? all ride was in a flat path with no wind.

Most of the pain of riding an upright bike has to do with the poor body
position, not the actual leg strain of pedalling. Recumbents don't cause
the usual pain that upright bikes do, so you can stay on and pedal much
longer usually.

I used to ride an upright road bike 26 miles every day, that was about
all I could stand without getting off and walking for a bit, just
because of the riding pain. After I got a recumbent, the "usual" ride is
35+ miles, and I still hurt less getting off the bike. I have nearly-no
pain at all, compared to what the upright bike felt like.

So I'd say you could go at least twice as far on a bent, assuming you
had that much time available to ride. Or you could hold a faster speed
(and still go considerably farther)--but some bent types are better for
speed than others (lowracers and highracers).
