These labels were used by our track team for middle school track meets. We used them the whole season. The athletes wore the labels on the front of the uniform jersey. we hand wrote most of the information and pre typed some of them. I didn't think they would stick. I was wrong - the labels stayed on the jersey all day long. At the finish long the official removed the label and simply put it on a card results board. They even stayed on the results board - some needed a little extra tape - they worked really well for our purpose.
