Long run with marathon-pace inserts

Blocks of goal marathon pace embedded inside a long easy run.

Also called: MP long run, specific long run.

The signature peak-phase session of most modern marathon builds. Inserting goal pace into a long run stresses fuelling, pacing and mechanics simultaneously, in the fatigue state where they actually break down. Treat it as a dress rehearsal: same shoes, same gels, same drink, same start time as race day.
