PFT madness

While my pull-up program continues, my running seems to have suffered a setback...but I think I know why. It's only been maybe 3 weeks that I have started my EZ 5-milers on mondays...and I think it's taking some time for my body to adjust to the longer distance at one time. I suspect it's probably a bit much to expect my body to continue making hard 3-milers without hit in my times. My wife has noticed a significant drop in her times as well...and I suspect this is to blame. I hope that the effects go soon...we have a 5K to run...and I have some PFT scores to raise.
