the result.“I covered 18-23 miles in my long training runs,” says Strand, “and I did the last 9-14 miles at marathon pace or faster. That was much faster than my previous long-run efforts of 17-22 miles at whatever pace I felt like running.”This kind

."NUTRITIONPass on the extra carbsBread, bagels, pasta, potatoes and pancakes - you just can't get enough, right? Wrong, says sports nutritionist Nancy Clark, author of Nancy Clark's Food Guide for New Runners (£12.95, Meyer & Meyer Sport). Running two or three miles

was already a marathon runner, and most of my runs were long and slow. My cross-country conqueror took a different tack. He focused on hard 1,200m intervals, subjecting his muscles to the kind of stress he’d face in competition. At times he also ran 400m
