Run, walk, run, walk
I tried the run/walk training method for our 4 mile run on Tuesday. The run/walk method has you run a mile followed by a brief walk, maybe for a minute or so. The theory is to give your body a chance to re-group, catch your breath, let the muscles recover before pushing them for another mile. Our coach's husband said he did this during the 5k and he ended up winning in his age group. I'm not saying this method is going to cut 3-4 minute off my average time (per mile) but if it does help in any way, no sense not taking advantage.
Overall, my run on Tuesday was horrible. I think it's still a matter of strengthening and conditioning. We ran the same distance (4 miles) on Monday and I felt great; but trying to run 4 miles the next day I just felt heavy and slow.
