    • Headphones and water belts
    • Re personal listening devices, we follow USATF rule 144.3.b (Assistance to Athletes):
      The visible possession or use by athletes of video, audio, or communications devices in the competition area. The Games Committee for an LDR event may allow the use of portable listening devices not capable of receiving communication; however, those competing in championships for awards, medals, or prize money may not use such devices.

    • Because we must be able to communicate instructions to you at certain points in our races, we specifically allow wearing headphones during the race, but we specifically prohibit wearing headphones at these points:
    • Start line
    • Aid stations
    • Turnaround 1
    • Midpoint
    • Turnaround 2
    • Finish line

    • Since we offer prize money ($250, $150, $100 for 1st, 2nd, and 3rd M/F), we ask you to follow this rule: if you expect to finish in the money, please don't wear headphones. Because of the specificity of Rule 144.3.b, we must disqualify potential money-winners whom we see wearing headphones or other two-way devices such as cell phones and the new talking wristbands. Sorry about that.

    • You may carry water or wear a hydration vest, but won't it slow you down? We have aid stations with water and Gatorade roughly every two miles.
