Swim Course
Set sail on the mighty Hudson

SWIM START

As in prior years, the swim course will run with the current which will be flowing north at the time of our race on July 11, 2021. Starting at 81st St., athletes will enter the Hudson and swim north to the exit at 99th St. and proceed to Transition at 101st St. (Riverside Park) for the subsequent bike leg.

PRE-SWIM START

  • Timing strap must be placed securely around your right or left ankle.
  • Remember your race-issued swim cap, wristband and clothing bag.
  • Give yourself ample time to get from Transition to Swim Start. The Time Trial start format goes faster than anticipated. It’s a one-mile walk from Transition.
  • Drop your clothing bag at a clothing truck near Swim Start. All of the clothing bags will be transported to the Finish Line Athlete Recovery for you to pick up after the race.
  • Listen for final water temperature announcements.
  • Wait in your assigned corral.  Practice swims are not permitted.
  • Sit-to-start for ALL athletes (no diving or jumping)

TIME TRIAL START

  • All athletes will be grouped with their assigned Age Group or Division.
  • Per industry standards, Age Groups are determined by your age at the end of the calendar year.
  • Age Groups/Divisions will be filed as a group onto the Start Barge. Athletes will enter the water APPROXIMATELY 15 ATHLETES EVERY 20 SECONDS.
  • Due to tide shifts and depth concerns, the race is sit-to-start only. No jumping or diving. Diving is grounds for disqualification.
  • Timing mats will be located at the starting edge of the Start Barge.
  • All athletes will receive a Timing Chip net time from the moment they leave the mats at the edge of the Start Barge until they cross the Finish Line timing mats. The swim time split will start once the athlete leaves the Start Barge timing mats and will end at the Swim Exit Barge timing mats.
  • Pro athletes enter the water first, followed by Group Red and Paratriathletes. There will be a 15-minute gap between Paratriathletes and Group Yellow athletes.
  • Any athlete missing their assigned Age Group start will be instructed to enter the water in the next wave.

SWIM Course Tips

  • Bring enough food and hydration with you to the swim start to stay nourished while you’re waiting for your wave.
  • The race has been wetsuit legal every year, so you will likely be able to wear your wetsuit. Stay tuned to event social media channels and PA announcements on race day for the official water temperature.
  • If you’re struggling in the swim, raise and wave your arm to get the attention of one of our many swim support teams on surfboards, jet skis and boats. If you need to grab onto a surfboard for a second you may do so without being disqualified, but you can’t make forward progress.
  • Don’t be surprised by the saltiness of the Hudson River!
  • Make sure you’re on time.

Water Quality

The historic Hudson River is the swim venue for the New York City Triathlon. The Hudson River is the cleanest it has been in 30 years and is considered bathing and recreation quality. The Department of Environmental Protection (DEP) monitors the testing on a weekly basis in the Hudson River to ensure the water meets the Triathlon’s strict standards. For more information on water quality, visit the nyc.gov DEP website or Riverkeeper to see what things are being done to improve the quality of the Hudson.
