Writing on Arms
Once you have a heat sheet, find all of your swimmer's events, heats, and lanes and write them on their arm with your Sharpie. This way the swimmer knows when to report to the block. A good rule of thumb: right arm on day one, left arm on day two, so you're not writing over the previous day's events. Complete this before sending your swimmer on deck — only swimmers, coaches, officials, and volunteers are allowed there.
