Into the Second week of training for the 10K

Last night was meant to be a 5 mile walk with more walk than run. The first mile was just under 8 minutes, then I walked a mile, ran another mile and a half, walked a mile and finished it running. Ended up with 50 minutes. I know I slowed about half way through it because it was meant to be an easy pace and I had pushed myself at the beginning. Anyway, it gets harder next week!!!
