Airport Loop I decided that I need to work on my endurance a bit as my 10K speed shows a prediction of a 2:55 marathon, but I know that I would die if I tried that right now. So, I ran the Airport loop at goal marathon pace effort. I started out with 6:50 miles just trying to stay ahead of the 7:00 guy. I was consistently around 6:50's the whole way except for the last mile where I put on a bit of a kick to finish with a 53:53 time. I am pleased with the effort as it shows that at least to the 8 mile mark my fitness is right where I want to be. Now to build more base and work on keeping that pace for a lot further. Total Time: 53:53 (6:44 miles) Ave Hr: 167 Max HR: 176 (during last mile kick) |
