This plan was designed for experienced runners who are training for the Runners World Half Marathon in Bethlehem. It is ideal for advanced runners who have averaged at least 30 miles per week for at least six months and who want to develop speed over a longer distance. Each week features 1 or 2 days of rest and 5 or 6 days of running. That includes hill work, race-pace runs, mile repeats, and long runs, which start at 10 miles and peak at 13 miles. The plan also includes notes on the Bethlehem course.
