I'm on week 4 of C25K (distance) with the goal of running a 5k on July 21. Monday I had a great run. I was able to complete all of the run intervals. Wednesday was okay. I got part way through the 2nd 1/4 mile run and was just so hot I couldn't run anymore. Today...I'm completely discouraged. I ran the first 1/4 mile interval at a much slower pace than I've been doing and only got about halfway through the 1st 1/2 mile interval when I had to slow to a walk. My muscles are tight and sore. Before each run I stretch for about 5 mintues and each run starts with a 5 minute warm up walk. Today that didn't seem to matter. My muscles seemed nice and loose until about halfway into the 1/4 run interval and then they seemed to tighten up and started hurting. It wasnt unil the last half of the second 1/2 mile interval that they seemed to have loosened up some.
If it matters I run on a paved bike path and wear Saucony running shoes that I got fitted for at a running store. I'd like to continue to run on the paved surface since the 5K is going to be on streets.
Any advice or tips are greatly appreciated. I'm still going to do the 5K either way and it's not timed so I don't have to run but I'd really like to be able to run the whole thing.
