I have been doing the couch to 5 K program and thought I was doing well. Had gotten up to week 5, but have been running on an inside track at our local rec center. Today I tried to run in a local 5K and I swear, I could not run longer than 3 minutes. It felt so different running outside on pavement and every joint was killing me. Plus, my jogging speed was slower than people who were walking! I am 50, weigh 30 pounds too much, and it took me a good 50 minutes to jog, (mostly walk) this 5K. I was a tad bit mortified. I know now I was NOT READY for doing this yet. Has anyone else been humiliated when attempting things like this? But I am going to keep at it. Every day I "wog"--(that is a barely jog) I feel great afterwards. But is there a big difference between inside and outside running?
