Thanks Jen. I've become acquainted with that stuff through Jason, MGBG, Pete Kemme, and the Soc Doc. It's very intriguing. I'd love to climb a rope. For the time being though I'm sticking with my running, rowing, and weights regimen, because it's comfortable--something I've been doing, off and on, for some thirty years--and it's easy to fit into my schedule. But eventually I'd like to get into something like that, along with more high-intensity training too. Oh, and did I mention I'd like to play soccer or basketball once or twice a week, and go on a long bike trip at least once a year? But I'm in an intensive work and child-rearing phase right now, so maintaining basic fitness is already an achievement. I picked up a Rainbow play station for free a month ago, and have climbed up and down that a bit! I envy your trail running. Sounds great. I've done some woods running in the past, but right now I live in the middle of the Twin Cities, so it's just neighborhood, fairgrounds, lake and river paths for the time being. We get out every weekend for picnics in city, regional, and state parks, but I can't really leave the fam for an hour to go off to run... Happy trails.
