Runner's trots?

I think I had my first real case of runner's trots on Sunday.  Sparing the vile details, I just about made it to the loos on the Common in time, seconds from a horrible clean up operation and a curtailed run.  On the up side, my new Nike running tights (Nike Tech Tights) are lovely; soft, warm, easy on the waist and grippy at the ankles.

Today I are be mostly hiding under a duvet on the sofa, coughing, blowing my nose, trying not to eat my own bodyweight in analgesics for the headaches due to sniffling pretty much all day for the last two days.  *wheeze*
