Thank you so much for the nice comments yesterday. I feel a little guilty because I wasn't asking for compliments, just trying to start a discussion, but the kind words really meant a lot to me. It's always helpful to hear other people's take on the psychological aspects of training. You all inspire and motivate me every day.
As promised, here's the conversation about CrossFit and cardio from the other day. (taken verbatim from the comments)
mtbjune: Question for you...and your readers...do you do any additional cardio work on top of your CF workouts?
Margaret: nope crossfit is plenty of cardio even the ME or heavy lift days your heart and lungs get a work out. I do Judo and Tae Kwon Do in addition to Crossfit. Now if your sport is marathoning you probably need to add in running but will need to log fewer miles than you used to. Crossfit endurance speaks to this on their website. most crossfitters can go out and run a 5k they might not enjoy it. But it won't take any extra training, that's why 5k and even 10k pop up as WOD they're almost considered rest days.
JamesD: June, my big thing is Brazilian jiu jitsu, and I find I don't need any cardio. I struggle mightily with the longer CF workouts, but in the 10 and under minute range where jiu jitsu takes place I've found, much to my sadistic delight, the college guys gas before I do.
miked: I usually run 5k or so a couple of times a week. But that's more for social reasons to run with the guys at work.
Amy: I go to spinning once a week, and I hike or snowshoe on the weekends. I also want to start up XC skiing again this year. I used to run some, but not so much anymore. Although sometimes I run from work to CrossFit!
