What is over training? I quite understand that running morning and night for 5 days a week will probably be deemed as over training but surely after a set period your overall fitness will increase. I currently do in any 5 day period Monday to Friday (weekend is for lash and recovery) Mon: 3 miler in the morning, 10 x 100m metre climb/scramble in the evening (speed and recovery very steep hill). then press-ups sit-ups and weights (upper body) Tue: 8 miler, in the morning, 45 min Spinning in the evening Wed: either circuits or run in the evening Thurs: press-ups sit-ups and weights (upper body) and then circuits Friday: 8 miler, in the morning, 60 min Spinning in the evening Weekend: watch sport and drink beer (occasional game of rugger) Having just read one of that Bear blokes books about his Everest escapades, He seemed to be training for about 8 hours a day..... He couldn't pass a hill without running up it no matter if he was in a dinner suit or not. So my question is if I start cycling to work and then running 2 steps at a time on every staircase I have to pass or use Am i over doing it?
