    Course

    The Luck of the Irish Triathlon course

    Everything is based at the LISD Aquatic Center on Memorial Drive in The Colony. The Sprint swim is 300 m in a 50 m indoor pool as a snake swim: you swim down a lane, duck under the rope and come back up the next, for 11 lanes in total, while the Super Sprint swims 200 m.

    Read the full course notes

    The bike is a 4.5 mile loop on Memorial Drive, Paige Road, North Colony Boulevard and Morning Star Drive, ridden twice for the Sprint (9 miles) and once for the Super Sprint, so keep count of your laps. The run is a 5K loop through the neighborhoods around the aquatic center (2 miles for the Super Sprint), and the whole course is on flat suburban roads. The Sprint starts at 7:30 a.m. and the Super Sprint at 8:30 a.m., making this an early-season race on the North Texas calendar.

    Race-day conditions
    The swim is in an indoor pool, so water temperature and open-water wetsuit rules do not shape your race. Late March mornings in The Colony are usually 45–60 °F at the 7:30 a.m. start, often breezy, with spring storms possible, so have a layer ready for the bike if you will be wet from the pool.

    What to train for

    A pool swim with lane changes rewards smooth turns and calm passing more than open-water skills: practise 25 to 50 m repeats ducking under a lane rope and getting straight back into rhythm.

    The flat bike suits a steady, slightly hard effort for 25 to 35 minutes, and short weekly bricks of a 20 minute ride straight into a 10 to 15 minute run teach your legs the switch.

    Rehearse your transitions too: on a course this short, a smooth T1 and T2 can be worth as much as a fitter swim.

    Taper

    Tapering for the Luck of the Irish Triathlon

    Start the taper seven to ten days before race day. Trim the volume in all three sports, keep short race-pace efforts in each, and do one last short brick so running off the bike still feels familiar. The course is flat, so pacing decides the day: rehearse your goal pace in short segments during race week. With the race on March 21, 2027, your taper starts around March 12, 2027.

    Luck of the Irish Triathlon training questions

    How long should I train for the Luck of the Irish Triathlon?

    Most athletes give a sprint triathlon eight to twelve weeks of focused training on top of an existing base. The coach counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.

    What is the Luck of the Irish Triathlon course like?

    Flat. Everything is based at the LISD Aquatic Center on Memorial Drive in The Colony.

    How cold is the water at the Luck of the Irish Triathlon?

    The swim is in an indoor pool, so water temperature and open-water wetsuit rules do not shape your race. Late March mornings in The Colony are usually 45–60 °F at the 7:30 a.m. start, often breezy, with spring storms possible, so have a layer ready for the bike if you will be wet from the pool.

    When should I start tapering for the Luck of the Irish Triathlon?

    Start the taper seven to ten days before race day.
