Murphys law or Sods law or is there a similar law that is cycling specific.

Went outside early this morning and noticed that there had been a few drops of rain but the cloud cover had thinned, just like yesterday, a perfect cycling day. Joined the Grinders for a hills ride following the BUPA route as far as Kersbrook. Light shower started at One Tree Hill, continues all the way to the top of Kersbrook hill, not enough to warrant stopping and donning the jacket. Fanging down to Kersbrook and the heavens open up and the shower becomes steady rain all the way back to Golden Grove. Sitting in the bakery cafe waiting for other riders to return, 2 riders return and we sit and chat, try to warm up, continuously appologise to the staff for the huge puddle we've created. After sitting there for a good half hour I suspect all 3 of us think it's time to move when a 4th cyclist returned having dutifully ridden the extended course. He's a slim lad and instead of walking to the table he just shivered his way across. Feeling very sorry for him I think we all agree by telepathy to stay and keep him company. Besides it was still raining very heavily. Finally our 4th arrival stops shaking and he's offered a lift home by Roger so it's off home, just a 10-15 min ride for me (no Strava) but it's still raining. So it's a spin up the Golden Way to get home and then a fast freezing downhill on McIntyre to home. Open the front door, take the wet shoes off and put the helmet inside, go outside again and "Bastard" it's stopped raining.
