with regards to running, here is my opinion:
you can and should tack on easy jogging to any days that you have time. it absolutely does not break you down but rather makes you feel better, and in the meantime increases overall fitness. seriously, just go out and jog as often as you can. doesn't have to be too long, and if you feel like crap slow down. if you still feel like crap turn around and go back inside. the gains I've made in fitness just from adding easy jogging to all my days have been crazy. of the 13 runs I do a week, 10 of them are easy jogging, with the other 3 being a tempo run, a long run, and repeats. of course, I push the pace on many of those 10 easy jogging days when I feel good, but if I feel bad jogging is perfectly fine. and in the recent months I've gone from barely managing 40 mpw at 8:00 average pace to 60+ mpw and most of it sub 7 flat, with tempo runs in the 5:40-5:50 range for 25+ minutes at a time. seriously, just GET OUT AND JOG. it won't stop you from recovering. it'll help you if anything. the best tempo run I've ever had, 4 miles at 5:32 avg pace, was after a day of pretty brisk jogging in the morning.
do it phaggots
edit: in other news, today I threw down 10x400 in 65-66 with 60 seconds jogging recovery. combine this with the aforementioned 4 miles at 5:32 pace and you've got the indicators of a sub 4:20 mile this season! I'm stoked as hell
