Fell down in ice on an Audax ride in Spring this year. No damage to bile, bruised knee think, but most annoyed at being wet and cold at the very start of a long ride.

Yesterday, another Audax ride, the instructions were to "walk" along a footbridge over a weir. I rode across, and at halfway the cement bridge changed to slippy metal grid. Felkl down at low speed, again no bike damage, but I had nice grid imprssion on knee.
