This program is a 20 week lead in. It becomes highly specific meaning it's perfect for runners targeting a competitive marathon race.

There is an emphasis throughout this program on teaching you pacing and consistency, both of which are critical to training and racing.

This plan progresses through 3 weeks of general conditioning to prepare you and introduce you to sessions you can expect throughout the 15 week Marathon specific phase (which will see your longest run of 36km and longest total week of 68.5km). Nearing your event the program will enter a 2 week taper.

The 15 week specific training block is broken into 4 week blocks (3 training weeks and 1 recovery week).

At The Distance, our running programs are designed using training fundamentals proven to enhance performance. Inserted strategically each week are various forms of aerobic, anaerobic and high intensity running specific training sessions.
