Using Run-Walk to beat my 2:39 marathon PB!

I&bringing the run-walk marathon back to try to beat my 2:39 marathon PB. The run-walk method is nothing new to running, and a lot of its notoriety can be credited to legendary running coach Jeff Galloway. However, I struggled to find scientific reasoning behind the run-walk method as well as any data on runners going under 3 hours using this method. Personally, I have successfully used the run-walk method to run a 2:45 marathon and 8hr 38min 100km. LINKS
