I am reading a lot about different techniques to accomplish a Full. Jeff Galloway suggest walking for 1-2 minutes every 5 miles or so. Yes, it will add 10 minutes of walk time to your final finish time, but it will prevent crashing at mile 18-20 and prevent you from having a very slow poor finish. That 1 to 2 minute walk will help your body reset mentally and physically.
He basically said that if you take that 26.2 in sections, 5 miles, then reset, 5 miles, reset... so on and so forth you can avoid the wall. Im all for that.
Nick, I know that we might have the same mentality of just go go go and NO walking, but I might have to try this. On really hot days and on long runs, I have been know to walk for 30 seconds to take in some fluids peacefully, Ill say that if you can fight the urge to walk again for a certain distance, it really does reset any pains in the legs or mental pains.
Weird.
