Multi-sport events at the beautiful Lago Mar Lagoon in Texas City are fast becoming the most popular in the area. The 12-acre crystal clear lagoon offers an experience like none other in the area, and we are happy to provide a choice of events that are sure to satisfy everyone’s athletic needs. Scheduled events include a Sprint Triathlon and Duathlon, a Youth race, and a 5K road race. The Sprint Triathlon will serve as one of the events in the USAT Paratriathlon championship series. See below for more information and to register.

WHAT TO EXPECT

This one-of-a-kind race brings athletes to the largest Crystal Lagoon around, found at the Lago Mar neighborhood in Texas City, TX. A true oasis from the hustle and bustle of the city, and the perfect place to race and get those competitive juices flowing after a crazy year.

The 12-acre Crystal Clear Lagoon is unlike anything ever created in this part of the world! It’s truly exceptional and is absolutely the best body of water you will ever race in around these parts!

Sprint Distance:

500m swim, 12 mile Bike, 5k Run

Begin with a 500 meter swim, transition to the bike and make two loops around the beautiful Lago Mar community. Slip into your running shoes, and then hit the ground running for a 5k course around the neighborhood of Lago Mar. After you complete the flat, fast oval shape loop, your finish line will be right back at the edge of the Lagoon, so you can immediately cool off and start your floating post race party!

Duathlon:

1.2 mile run, 12 mile Bike, 5k Run

The duathlon mimics the triathlon course; the exception being that the swim is replaced with a short, 1.2 mile out-and-back run on the sidewalk bordering the neighborhood lake.

Aid Stations & Post-Race Food & Drink

Hydration stations will be set up along the course at frequent locations. Running with a hand held bottle or belt is appreciated to keep the area tidy.

Post Race:

After the race, find your friends and/or family; and enjoy the Lagoon and LagoonFest Texas the rest of the day. Your Race Entry doubles as a LagoonFest Texas pass. Lago Mar Lagoon is unlike anywhere else, and you will not want to rush off after the finish line!

WHAT TO EXPECT

This one-of-a-kind race brings youth triathletes to the largest Crystal Lagoon around, found at the Lago Mar neighborhood in Texas City, TX. A true oasis from the hustle and bustle of the city, and the perfect place to race and enjoy amazing family fun!

The 12-acre Crystal Clear Lagoon is unlike anything ever created in this part of the world! The Lago Mar Lagoon is truly exceptional and is absolutely the best body of water you will ever race in: Crystal Lagoons are cleaned with advanced technology and truly crystal clear! This is the safest and most fun course we have ever put together.

Youth Triathlon Short Course (Ages 6-10):

75 yard swim, 2 mile bike, 3/4 mile run

Youth Triathlon Long Course (Ages 11-15):

150 yard swim, 4 mile bike, 1.5 mile run

Keep in mind these are USAT Ages - the age of the participant they are on December 31st. If a child is 10 years old on race day, but turns 11 before the end of the year; the USAT Triathlon age is 11.

This swim is perfect for a youth course, as we will have lifeguards all over the water, and the swim course is in crystal clear water. There are no lanes and swimmers may not be able to touch the bottom the entire way. Not to worry, it is a short swim to the side of the lagoon or to frequent safety kayaks if needed.

The bike and run course will all be in the safety of the beautiful Lago Mar neighborhood.
