I need some help figuring out why I'm having such trouble running post-C25k. I ran a 5k around this time last year, and then didn't run for quite a few months after that, but was still relatively fit when I started training again in January. I skipped a few C25K session this time round as I seemed able to manage it. As I've signed up for the BUPA 10k at the end of May, I downloaded the Bridge to 10K app and tried the first run yesterday. I got a really bad stitch in the second 10min section, so stopped. I tried again this morning, and had to stop again in the second 10min section because I felt completely exhausted. It's really strange, as I know I can run 30mins in one go, but can't seem to even manage 20mins with a break in the middle on the Bridge to 10K!
I don't know if it's because I've been exhausting myself exercising at the gym on my non-running days (and working pretty hard too), or if it's all in my mind (the thought of running a 10k horrifies me, and I remember swearing I'd never do anything more than a 5k after my run last year!) Or perhaps I'm not eating the right things? Please help! I've not got long until I have to do this, and can't afford any setbacks Any advice would be much appreciated!
