Shucks, that don't look hard. You're just talking about doing 1 "round" right? I could prolly start on L8. Sure, it'd take 6:40 to do (plus a little overhead) but you might not even work up a sweat since you're doing it so slow.
Of course, I say that now, here in my air conditioned office at the law firm downtown. What I say this evening at home might be a different story altogether. :)
