IRONMAN 70.3 Dallas
A rolling Half-Ironman on the calm shores of Lake Lewisville — your first big-distance finish line is waiting in North Texas.
Where it is
Dallas, United States
Is this your race?
IRONMAN 70.3 Dallas sits at the friendlier end of the half-iron world. The lake is sheltered and calm, the bike avoids any serious mountain, and the run loops a well-surfaced nature trail where your crew can cheer you on three times. The one thing to respect: March water in Lake Lewisville can be cool, so cold-water swim practice belongs on your training plan from day one. Beginner fit 4/5: 70.3 baseline 3, +1 sheltered lake swim with wetsuits likely allowed, +1 flat/gently rolling bike and run — total 5, capped at 4 (maximum for a 70.3 distance).
✅ You’ll love it if…
- You want a big-distance debut with a forgiving swim venue
- You thrive in mild spring weather rather than summer heat
- You love a run course where friends and family can find you easily
- You are based in Texas or the South-Central US and want a low-travel first 70.3
⏳ Build up first if…
- You have never swum in open water below 18 °C — add cold-water acclimatisation sessions before race day
- You are still building your long-ride base — aim for at least one 70–80 km training ride before taper
- Multi-loop runs feel mentally tough for you — practise breaking them into separate 'mini races' in training

The course, demystified
The race unfolds entirely around Little Elm Park on the southern shore of Lake Lewisville. You swim one loop in the lake, ride out through rural North Texas roads, then return to run three laps on the park's nature-trail system — all within easy reach of your support crew.
Respira y flota (breathe and float) — the start and finish are both at Little Elm Beach, making this a single out-and-back loop in Lake Lewisville. The lake is described as calm open water, which is a genuine gift for first-timers who dread surf and chop. That said, March water temperatures are typically estimated at roughly 14–19 °C, so wetsuits are very likely to be allowed (and strongly recommended). Confirm the official rule in the athlete guide as race week approaches.
The bike leg rolls through rural two-lane roads and suburban communities north of Dallas. Third-party sources report elevation gain of roughly 280–427 m — no sustained mountain climb, just a series of gentle rollers that keep the course interesting without punishing beginners. Expect a fast, open feel with good road surfaces.
Three loops on the Little Elm nature-trail system. The surface is described as smooth and consistent, and the multi-loop design means spectators can cheer you on at the same spots again and again — a real morale boost in the final kilometres. Third-party sources estimate roughly 50 m of run elevation gain, making this one of the more forgiving 70.3 run courses you will find.

How to fly in
Dallas–Fort Worth International Airport (DFW) is the nearest major airport, roughly 30–40 minutes from Little Elm depending on traffic. A rental car is strongly recommended — Little Elm is a suburban community and rideshare availability near the race venue early on race morning is not guaranteed. Book your car early; demand around large race weekends can push prices up.
Hotels near the start
Where to stay — by what matters to you
Closest to the action
Staying in Little Elm puts you within minutes of Little Elm Beach, the transition area and the run course. Race-morning logistics become much simpler when you can walk or take a very short drive to transition. Check whether an official hotel block is announced — it may not exist for a venue this close to the park.
🏨 See stays · affiliateMore hotel options, easy access
The Frisco and North Dallas corridor offers a wider range of hotels and price points, with a manageable drive north to Little Elm. This is a good fallback if Little Elm accommodation fills up or if you prefer a larger hotel with a pool for pre-race warm-up swims.
🏨 See stays · affiliateGetting around & the rest of the trip
Arrive at DFW by Friday 12 March to allow time for bike assembly, athlete check-in and course familiarisation without rushing.
Check-in and race briefing are typically held Friday–Saturday; confirm exact times in the official athlete guide once published.
Bikes are usually racked the afternoon before the race (Saturday 13 March); verify the cut-off time in the athlete guide.
Sunday 14 March, 7:00 AM start. Be at transition well before the gun — aim for at least 90 minutes early to set up, use the facilities and warm up.
Book your return flight for Monday 15 March at the earliest; post-race celebrations and stiff legs make same-day travel a gamble.

Bringing a support crew?
Little Elm Park is genuinely one of the more spectator-friendly 70.3 venues you will find. The swim start and finish are both at Little Elm Beach, and the three-loop run means your crew can cheer you at the same spots three times — which is three times the noise and three times the motivation.
- Little Elm Beach: watch the swim start (7:00 AM) and the swim finish; this is also where the finish line is located — prime real estate for the whole day
- Transition area (T1 and T2): cheer athletes as they move from swim to bike and bike to run — check the athlete guide for spectator access rules
- Run loop: the nature-trail course is designed for spectator access; pick one or two spots on the loop and you will see your athlete pass three times
- Finish chute: be here for the final 200 m — the atmosphere is electric and your athlete will remember seeing your face at the line
