Oh, were out there, and in here too, but there are better places to specifically discuss the use of 'bents for LD. In here I try to not use the R word very much.
I never was interested in LD till I started riding a recumbent. The 'bent made rides beyond 4 or 5 hours a lot easier and a lot more enjoyable. I am certain I would have never ridden longer than a century had I not discovered them.
The Giro 20 is a good bike ( I used to have one), and certainly could be used for LD, but I would recommend that, given some time, you'll want to keep your eyes open to trying out a higher performing machine.
