Riding through a hail storm.
Yeah, sounds F'd up, but I got caught in a hard hail storm on the way home today. Had to endure about 3 miles of pebble sized hail at 60 mph. Hurt like mad, my head was ringing, the bike was cutting through a wall of water and hail like an ocean liner.
At the end of it all I raised my fist to the sky and was laughing like a lunatic. I felt great for some reason. Still do. Got a huge bruise on my bicep where the hail was pelting me through the gaps in my riding suit.
