The Run/Walk Plan

I received an e-mail enquiring as to how I ran such long distances. While in training for a marathon I occasionally use the run/walk plan to break through the proverbial wall. Here is the run/walk plan in a nutshell:

• Run for 1 mile at your normal pace.
• Walk for 60 seconds
• Run the 2nd mile
• Walk for 60 seconds and drink a cup of a sports drink
• Repeat 24 more times

I have noticed that after using this program during my longer runs during training I can run faster, farther and feel better at the end of my long runs. I used the run/walk method during the St. Jude Memphis Marathon and finished with my personal best time for a marathon.
This run/walk method I have described is based on a plan developed by Jeff Galloway. Jeff Galloway ran the Chicago Marathon in 3:30 using his plan.

How do you break through the wall when you are training for a marathon?
