i missed my long run yesterday as it was too icy, and i figured i'd rather miss a day (and just for the record, it was 2 days off as saturday is my rest day) than miss 6 months because of a broken bone or something....i think runners get too obsessed, with food, training and all that....
i'm a pretty serious runner, and am as scared as the next one about the descent into the armchair, but is hasn't happened yet, and2 days off is just fine....
as for marathon schedules, i was constantly injured in preparation for my last one, so only managed 20-30 miles a week in the 4 months preceeding it (a week of which was spent in hospital too, so no training at all there) and my time was 15 mins better than i aimed for (3.30 instead of 3.45.) the marathon was quite easy and great fun...the time was a bonus....
