I think they call it Bonking ...

...except that it would have had to have been mid-long-run according to Wikipedia.

Factors:

• I set out a little too fast,
• I drank several glasses of wine last night, 
• My quad pain was acting up, and
• I had a deep cramp in my right side. 

So I walked some, ran some and cut it short and went home. I almost want a do over. But instead will go to acupuncture and do a pilates session tomorrow followed by a deep tissue massage and prep for my Saturday 9 mile run.

Some days are just like this... even in Australia.
