Putting Fatigue

During lunch today I practiced putting in the heat by playing The Range disc golf putting game with a coworker.  I made it through nearly 200 putts before my putters started floating errant.  The sun and 85 degree heat had finally caused putting fatigue to set in and this was a prime putting practice opportunity.  I was determined to keep up my putting form and focus during practice so it would come much easier while on the course.
