Blatantly spamming this on various 'bent focused forums because I thought it was a great bit of info. Did a search in the forum and didn't see this posted already, so I'm passing it along (please correct me if I'm wrong).
Just got a link to an interesting article via Twitter, titled "Focus breathe: how to climb fast with a recumbent" http://www.fietsersafstappen.nl/engl...th-a-recumbent
Not sure how old the article is, but it brings up a great technique for improving your climbing power. Enjoy!
