I should provide some back drop for those that will look at my times and wonder why I am so slow. My fastest marathon is 4 hours but I haven't broken 5 hours in 10+ years. The last sub 5 also was before my last knee surgery which was followed by a 20 lb weight increase which now is closer to 30. My focus instead turned towards running trails and finishing short to mid distance ultras. My theory was that as I added distance I would lose the weight and with the weight off I would get faster. It was a good theory that has been complicated with years of dealing with injuries. So this year is simply about getting my distance in without pushing hard especially on uneven surfaces (trails) which I hope will reduce my chances of injury. I also believe the run-walk method will reduce the stress on my legs as they get used to roads again, and at this point in time, I am pretty much injury free so it's working.
I also have a pace (blue) versus heart rate (red) chart and it shows my heart rate never going to high but going up as the miles increased. I also can see that my recovery pace as shown by the lower HR average during the walking breaks trended up as well.
So next week I will push the long run to 17 miles and use the same process. After that I will have just 2 more long runs before the first marathon. And after the first marathon no more long runs, just marathons.
