am) 8 miles 50:00. My back is no better but my willingness to ignore it is. If I over extend my stride there is a moment where my forward leg absorbs my body weight and my entire leg loses all strength- nearly giving out. As my body moves forward and the weight is distributed in a more balanced way over my leg the strength comes right back.. so for a split second it's like I'm going to fall on my face. Kind of a tricky thing! I was able to run a 20:00 tempo at HR 165-170. The first mile was 5:30 then I decided not to look at pace and to simply run. The trail is very snowy and the wind is kicking today.. pace is never accurate with those conditions.
Also, when I engage my lower abdominals, if I blow my nose or sneeze, then my entire lower back in to my pelvis feels like I got hit with a cattle prod.. it's quite intense! With 9 days to go and seeing that I can function.. I'm not losing too much confidence.
