I did an 11 miler this morning with 6 of them at goal marathon pace. Felt very comfortable and was getting faster every mile. Could have held pace for another 6+ miles with no trouble. This is in spite of being in the middle of the biggest mileage I've run in years and i live in Texas where the temp and humidity made it "feel like" 90 degrees when I finished at 7am.
I know it's just one run, but do I have reason to feel pretty confident if I am still 6 months out from goal race and hitting runs like this during base building?
