  Same beautiful venue featuring improved organization with help from local triathletes. Great for beginners and experienced athletes!

  Note: Given that we've been getting more non-licensed racers over the past couple of years, we have dropped USAT sanction to save non-licensed racers from having to pay the $15 one-day license.
