🎯

Is this your race?

This is one of the friendlier half-distances on the calendar — a lake swim, a flat bike, and a spectator-lined loop run all work in your favour. The one thing that demands respect is the water: March in North Texas can leave Lake Lewisville cold, and you will want a wetsuit and a solid open-water practice block before race day. Beginner fit 3/5: 70.3 baseline 3, +1 flat and gently rolling bike and run, -1 cold water (reported 14–19 °C in March, dipping below 18 °C, wetsuit status unconfirmed); no heat or altitude penalty applied.

✅ You’ll love it if…

  • You want a first 70.3 without a mountain bike leg to worry about
  • You thrive in mild spring weather and enjoy lakeside racing
  • You like a loop run where your crew can cheer you on multiple times
  • You are based in or near Texas and want to minimise travel logistics

⏳ Build up first if…

  • You have not yet practised open-water swimming in water below 18 °C — add cold-water acclimatisation sessions before race day
  • You are new to pacing on exposed, wind-prone roads — practise riding at race effort on flat, open terrain
  • You have not completed a sprint or Olympic-distance triathlon yet — a tune-up race in the months before will build confidence

Not yet? That’s normal. Start here → take the 2-minute Readiness Assessment.

The course, demystified

The race begins and ends at Little Elm Beach on Lake Lewisville. The swim is a single loop in calm freshwater, the bike rolls through rural two-lane roads and quiet suburban neighbourhoods, and the run follows the Little Elm nature-trail system on a three-loop out-and-back that your supporters can walk to easily.

🏊 Swim · 1.2 miles / 1.9 km

Respira y flota (breathe and float) — the start is a single loop in Lake Lewisville, a freshwater lake with a sandy beach entry and exit at Little Elm Beach. Freshwater lakes are generally calmer than ocean swims, which is a real advantage for beginners. The main variable is temperature: reported figures range from roughly 14 °C to 19 °C in March, which is cold enough to cause breathing shock if you jump straight in. Plan to wade in slowly, splash your face, and take a few breaths before you start swimming. A wetsuit is widely expected to be permitted (check the official athlete guide to confirm), and it will help both with warmth and with buoyancy.

Rookie trap: Cold water can trigger an involuntary gasp reflex — the fix is simple: enter gradually, get your face wet before you go, and give yourself 20–30 seconds to settle your breathing before you push off. Never skip this step.
🚴 Bike · 56 miles / 90 km

The bike course winds through rural two-lane roads and suburban communities north of Dallas. Third-party sources estimate roughly 263–280 metres of total climbing — that is very modest for a 90 km ride, roughly the equivalent of a few gentle highway overpasses. There are no sustained climbs to worry about. What you should prepare for instead is wind: flat, open roads in North Texas can expose you to a headwind that feels harder than a hill. Ride at a steady, controlled effort rather than chasing fast splits early — you still have a half-marathon to run.

Rookie trap: Wind on exposed flat roads is easy to underestimate. If you push hard into a headwind on the outbound leg, you will pay for it on the run. Practise riding at a conversational effort even when conditions tempt you to go faster.
🏃 Run · 13.1 miles / 21.1 km

The run follows the Little Elm nature-trail system on a three-loop course described as smooth and consistent. Third-party estimates put elevation gain at roughly 28–50 metres — essentially flat. Three loops means you will pass the finish-line area multiple times, which is great for spectators and great for your motivation. Aid stations and crowd support are accessible throughout.

Rookie trap: Three loops can feel mentally repetitive, especially if you go out too fast on loop one. Treat each loop as its own mini-race: start conservatively, hold steady on loop two, and give what you have left on loop three.

Getting around & the rest of the trip

✈️ Fly into DFW
Book flights early — March is a popular travel period and prices rise as the date approaches.
🔗 Book accommodation early
Little Elm has limited hotel inventory close to the venue; check the official IRONMAN hotel partner list and book as soon as registration opens.
🔗 Sort your bike transport
Decide early whether you are flying with your bike, shipping it, or renting locally — each option has lead-time requirements.

Your countdown: train and book

One timeline that fuses fitness milestones with the trip deadlines first-timers miss. Coral dots = book-it deadlines.

12+ months out (now – Spring 2026)Register and build your baseSecure your entry as soon as registration opens — 70.3 events sell out. Start or continue a consistent swim-bike-run routine three to four days a week. No big sessions needed yet; the goal is habit.
9–12 months out (Spring – Summer 2026)Book flights and accommodationLock in your DFW flights and Little Elm or Frisco accommodation. Check the official IRONMAN hotel partner list first. Sort out your bike transport plan — flying with a bike, shipping, or renting locally.
6–9 months out (Summer – Autumn 2026)Do a tune-up raceEnter a sprint or Olympic-distance triathlon to practise transitions, race-day nutrition, and open-water starts in a lower-stakes environment. This is one of the best investments you can make.
3–6 months out (Autumn 2026 – Jan 2027)Build long sessions and cold-water practiceExtend your long bike rides toward 3–4 hours and your long runs toward 90–100 minutes. Add open-water swims in cool water if possible — you want your body familiar with the cold-water breathing response before race day.
6–8 weeks out (Jan – Feb 2027)Dial in race nutrition and gearTest every product you plan to use on race day — gels, bars, electrolytes, kit — during your long training sessions. Nothing new on race day is the golden rule. Confirm your wetsuit fits and is race-legal.
2–3 weeks out (late Feb 2027)Download the official athlete guideRead the athlete guide cover to cover: confirm wetsuit rules, cut-off times, transition procedures, and parking. Taper your training volume while keeping intensity. Pack your gear list early.
Race week (8–14 Mar 2027)Arrive, check in, and restAim to arrive at least two days before the race. Attend the athlete briefing, rack your bike, and walk the transition area. Eat familiar foods, hydrate well, and sleep as much as you can. On race morning, arrive early, get your wetsuit on, and wade into the lake slowly to acclimatise before the start.

If-Then: your calm-in-chaos grid

A plan for the moments that scare you. Read it twice the night before.

IfThe water temperature is below 18 °C on race morning
ThenWear your wetsuit (confirm it is permitted in the athlete guide), enter the water gradually, splash your face, and take slow breaths for 20–30 seconds before swimming. This is normal and manageable — thousands of athletes do it every year.
IfYou feel the wind picking up on the bike
ThenResist the urge to fight it. Drop into a lower gear, keep your cadence smooth, and hold your planned effort level rather than your planned speed. You will make up time on the sheltered sections.
IfYou go out too fast on loop one of the run
ThenSlow down immediately — do not try to 'bank' time on a three-loop course. A steady loop two sets you up for a strong loop three.
IfYou feel overwhelmed in the swim start
ThenMove to the outside of the group, slow your stroke, and focus on long exhales. You are in a calm lake — there is no current pulling you anywhere. Give yourself permission to breaststroke for 30 seconds until you settle.
IfRace-day weather is warmer than expected
ThenStart drinking electrolytes earlier on the bike, reduce your effort slightly in the first half, and pour water over your head at aid stations. Check the official forecast the day before and adjust your nutrition plan.

Bringing a support crew?

Little Elm Beach is a natural spectator hub — the swim start, T1, T2, and the finish line are all based there, and the three-loop run means your supporters can cheer you on several times without moving far.

  • Little Elm Beach: watch the swim start and finish, both transitions, and the run finish — all in one place
  • Little Elm nature trails: the three-loop run course means you will see your athlete pass at least three times; find a spot near the turnaround or the start of each loop
  • Bring sunscreen and layers — March in North Texas can be mild but mornings are cool and conditions can change
