Hi I was lucky enough to get a ballot place in 2013 London Marathon. I am trying to devise a training schedule. It will be my second marathon. I have had ITB issues previously once I increased my mileage over 14 mi. it continued to play up throughout the latter part of my training & the race. I stopped running for a few months after the race to give it time to calm down. I recently did the Great South Run 10mi, although not in a brilliant time due to lack of running training. I would like to do London in a sub 5:00 without having ITB pain!!! My plan is to start training this month to build up my mileage slower. I will drop back & start at 5mi. Then increase by a mile a week up to 18mi dropping back by 2mi every 4th week. I will then add in one 20mi & one 22mi end march time. My question is that a friend of mine suggested I train in a 9 day cycle instead of 7 but this has confused me a bit & i cant find any 9 day cycle examples online. I plan to do one long run a week (has to be at weekend), one short 30min run, one interval session, two strength training sessions & one spin per week. Not sure how I can get a 9 day to work for me given when my long run is plus I want to stick with a spin on one set day & one strength class on another set day (ViPR/kettle bells/body pump). Given that I am starting earlier to build the mileage up slower, would 7 day still be best for me? Any thoughts, opinions or suggestions greatly apprieciated. Thanx in advance.
