A. Not that often, actually: only three times a week; usually Tuesday mornings (6 miles or so); Thursday mornings (8-10 miles) and Saturday morning long runs (12-22 miles depending on how close the next marathon is). Interestingly, because I run marathons now about once a month, my downtime recovery (usually a week of no running following a race) and the marathon itself, are part of the cycle of training keeping the momentum of training-readiness going.
