Average Training Week for a Sub-3 Marathon

An average week

This plan is a general guide for a sub-3-hour marathon, featuring key workouts: a long run (endurance), a tempo run (stamina), an interval run (speed), and an easy run (recovery). Hard efforts like intervals and tempo runs are followed by an easy run, rest, or cross-training to prevent overtraining. It’s not a rigid schedule—adapt it to your needs!

Here’s a typical week as a general guide for runners chasing a sub-3 marathon. Each workout has a purpose (hover over the cards to see why), but you don’t need to follow it exactly—tweak it to fit your fitness and schedule.
