This training plan progresses from beginner (low base miles) to half marathon walk/ruck to full marathon walk/ruck. It leverages and extrapolates Hal Higdon’s "Half Marathon Walking Program" as the foundation—with an optional weight component layered in from GORUCK’s marathon rucking principles. Built by Rawlogy Labs (rawlogylabs.com). Where you see *, these are the days you can add weight if you're rucking the race(s).
