Hit the Wall/5:10

I've hit the wall. In the last week I had the un pleasure of working a total of 28 hours in a 36 hour period. The other 8 hours were devoted to (broken) sleep and even a cheeky ride.
The rest of the week went busily, with me being able to hit all my training and family goals. Today has me feeling 10:5. Ten pounds of shit in a five pound bag. man.
Last two rides, solid as, one on and one off the road. today. hit out for an hour "start of the training week stretch the legs ride" and turned back after 5 minutes. It was beginning to drizzle. I just couldn't stand the thought of riding in the rain. That is the first (and hopefully last) time I have ever turned back from a ride. gutted.
