I'd planned my final run of c25k this morning, but knew I hadn't run 5k in the half hour - nothing like it! So today I thought I'd run the Cardiff Parkrun marked route, and see how long it took me. I did my warm-up walk without Laura, then started listening and running at the same time; that way I have her encouraging me at the end of my run, rather than telling me to slow down, when I still had 5 minutes to go! God, it's hard! It took me 35'45" (so, in the end she did tell me to slow to walk while I still had to run!) and my warm-down walk was certainly NOT very brisk - more like a crawl...but I did it!
If you're just starting out - go for it! Although I'm tired, I simply couldn't imagine being able to do this 9 weeks ago - farther than I've ever run, even as a child! (and I'm 54!)
