I managed to complete a 16 mile run/walk yesterday - just!! Started out at 6AM at 25C and 4 hours later it was 30C+. By noon, after I had driven home it was 34C. Considering it is supposed to be now Autumn, Summer is not letting go. On each of my 14-16 mile longruns over the past 6 weeks or so I have been really struggling over the last mile - but they have all been under the same conditions. It could be the heat by the time I am getting close to the finish, or my mental state or my lack of endurance?? Anyway, this morning I do take heart and encouragement from the fact that I "feel" completely recovered in less than 18 hours.
Who else here is in the middle of marathon training? What distance are you at and how are you tracking??
