I'm right with you there Alan. One of my best throwing days came last year in Tucson, after driving all night with just a couple hours sleep to get there. My mind was a little out of it, but it forced me to stop and think about everything I was doing.

I was having an ok day, throwing some good stones when my hernia started acting up. I have an umbilical hernia, so every once in a while it will feel like my insides are trying to come out through my belly button. I'm ok, but I have to be careful how I hold my torso and bend over, etc...

I had my best hammer throws ever that day, still unmatched. I was concentrating on holding my form correctly and not aggravating my hernia any so I was totally focused on doing the winds correctly and not trying to force it.

Now in Phoenix earlier this year I had the opposite experience. I drove in that morning, again no sleep but this time I was running late. I signed in and got on the field just as my turn to throw was coming up. I literally ran onto the field, changing into the game shirt and stepped up to the caber. I totally flubbed my first two attempts because I was so focused on getting caught up.
I stopped before my third attempt, calmed myself, and then had an 11:30 turn.

Just had to get my head in the game.
