This plan is built on maxing out at 60 miles a week. It starts at just 50 miles and build towards a few weeks at 60. However it is easy to adapt the plan a few miles this week as on non workout days feel free to add or subtract a mile from the runs so that can swing each week 5 miles. The Plan is focused on two hard days a week and 6 runs a week. The option is there for 4 long runs of twenty miles or more. You should have at least 4 weeks of base training under you before starting this plan ...
