Potential Pain & Suffering...

Saturday's approaching and I'm gonna go do the insane thing again:  Run 21 km without much preparation.  I ran about 3 km last Monday and another 3 km on Tuesday and then the cold took me, so I haven't done anything.  Wish me luck or call me a fool, but please understand that if I'm grumpy next Tuesday when back at the office, it's because I'm still suffering from my own foolishness!!!
