Ugh! I'm struggling. On Tuesday I got up at crack of dawn to tackle week 8 run 1. I managed about fifteen minutes before I turned round and walked back home. My legs felt like lead! I had absolutely no oomph. I put it down to the early start and going out on an empty tummy. Yesterday was a rest day, and then today I decided to have another go at it, but this time I went out for my jog after work. And the same thing happened. Fifteen minutes and pow, I hit the wall. Or the ceiling. Or the plateau. or whatever it is you hit when you just can't carry on. Again, I turned round and walked back home. I'm feeling really demoralised And my 5k Women's Running is looming, on the 4th June. I need to get my stamina up. Help! Any advice gratefully received.
