At a glance
IRONMAN 70.3 North Carolina is a half-distance triathlon held each October in Wilmington, North Carolina, on the course known locally as "Beach to Battleship," which began in 2008 and joined the IRONMAN 70.3 series in 2016. The 1.2 mile swim is a tide-assisted channel swim at Wrightsville Beach. The 56 mile bike runs out through the coastal countryside of Pender County and back, with only around 300 to 400 feet of total climbing. The 13.1 mile run passes Greenfield Lake twice before finishing in downtown Wilmington, across from the Battleship North Carolina. It is one of the flattest, fastest courses on the 70.3 calendar and a regular sell-out.
North Carolina is the right race if you want the course to help you, not test you
You are somewhere between forty and sixty. You run something. You haven't been properly fit for a while, and you want a race that rewards the work you've actually put in, rather than punishing you for the hills you couldn't train on.
North Carolina is a good choice, for four reasons.
If you want hills to test yourself against, look at Maine or Bolton. If you want a course built to produce your best possible time, North Carolina is one of the strongest choices on the 2027 calendar.
The swim gives you a push, not a fight
Wrightsville Beach's Banks Channel swim runs with an incoming tide, which carries you toward the finish rather than against you. For a nervous open-water swimmer, that's the difference between dreading the start and getting it out of the way early. How 70.3 training fits around a full diary.
The bike removes the excuse of terrain
At around 300 to 400 feet of climbing across 56 miles, this is one of the flattest bike courses in the series. It isn't the most scenic — long, straight highway through pine country — but it is honest: your result reflects your fitness and your pacing, not whether you can climb.
The date sits in a kind window
Mid-October on the Carolina coast is mild, typically 64 to 75°C, which is considerably friendlier than a summer race in the same region. Your hardest training weeks land in the late-summer heat, but race day itself rarely punishes you for it.
And it has a genuine sense of occasion
Finishing across from the USS North Carolina battleship, in a town that has hosted this race in one form or another since 2008, gives the day more weight than a generic out-and-back.
The swim — 1.2 miles, Banks Channel, tide-assisted
The swim is a point-to-point course in Banks Channel at Wrightsville Beach, timed to run with an incoming tide that carries you along for most of the distance. Water temperature typically sits in the upper 60s to low 70s°F, comfortably within wetsuit range in most years.
The tide is the whole story. An incoming tide helps push you down the channel, which is why times here tend to run faster than a still-water swim of the same distance. A north wind, common that time of year, can put some light chop on the water, but it rarely becomes a real factor.
What that means for how we train you
A tide-assisted swim rewards a relaxed, well-sighted stroke more than raw power — your job is to stay straight and let the water do some of the work. Your swim block builds sighting technique and comfort swimming alongside a crowd in a current. If open water is new to you, start with our guide to open-water swimming for nervous beginners.
The bike — 56 miles, flat, out through Pender County
Out from Wrightsville Beach onto MLK Parkway and US 421, through Pender County and the pine country outside Wilmington, over the Isabel Holmes Bridge, and back. Total climbing is around 300 to 400 feet, across the full 56 miles — about as flat as a 70.3 bike course gets.
It isn't scenic, and that's fine. Most of the route is a long, straight, multi-lane highway through pine forest. It's not the course you ride for the views; it's the course you ride for the time on the clock.
The wind decides more than the road does. A north wind is common in October, which usually means a headwind heading out and a tailwind coming home. It's a manageable trade-off, but it means the discipline on the way out matters more than the terrain does.
What that means for how we train you
On a pancake-flat course, the limiting factor is almost always pacing discipline and aerodynamic position, not power on hills. We build sustained tempo work at your tested number, with the aim of holding it steady into a headwind rather than surging and fading. The same logic applies to how we set your heart-rate zones.
The run — 13.1 miles, around Greenfield Lake, to the Battleship
From North Front Street south along the Wilmington waterfront to Greenfield Lake, where you pass around it and then back around it in the opposite direction, before heading north through downtown to the finish at Riverfront Park, across from the Battleship North Carolina. The course is flat throughout, with shade around sections of the lake and more open, exposed stretches downtown.
Two passes of the same lake is a pacing test, not a terrain test. With nothing to climb, the run comes down entirely to how well you managed the bike and whether you've rehearsed holding an even effort on tired legs.
What that means for how we train you
With elevation removed from the equation, your run block focuses on pace discipline off the bike and fuelling: brick sessions to rehearse running at your target pace straight off a fast, flat ride, and a nutrition plan tested well before race day, not invented on it.
Five things that ruin race day at North Carolina
Every one of these is a coaching problem, not a fitness problem. They are decisions made under fatigue by people who haven't rehearsed them. That rehearsal is most of what you are paying us for.
- 1
Treating the tide-assisted swim as a free pass
It helps, but it doesn't swim the race for you. Athletes who haven't rehearsed sighting in a current still drift off line and add distance.
- 2
Riding the headwind leg too hard
The wind usually turns to a tailwind on the way back. Athletes who burn matches fighting the headwind out have nothing left to use the tailwind for.
- 3
Underestimating a "boring" bike course
A flat, straight highway with no terrain to break it up is mentally harder to pace well than it looks. Treat it as a discipline problem, not an easy ride.
- 4
Losing focus on the second pass of Greenfield Lake
Seeing the same scenery twice on tired legs is where concentration — and pace — slip. Treat each pass as its own short race.
- 5
Booking accommodation late
This race has sold out in multiple recent years, and Wilmington and Wrightsville Beach fill up with race weekend visitors. Book early, same week as you register.
Your coach: Stephan Weyers
Stephan is a co-founder of Wingman, an IRONMAN Certified Coach, a USA Triathlon Certified Coach and a TrainingPeaks Certified Coach. He is also a sports lawyer and entrepreneur, which is relevant to you: he didn't come to this sport as an athlete with time to spare. He came to it, in his own words, as an "IRONMAN bucket-list wannabe," and worked through to multiple IRONMAN finishes and then to coaching.

Stephan Weyers is co-founder of Wingman Multisport and an IRONMAN Certified Coach. A sports lawyer by trade, he went from bucket-list Ironman to multiple Ironman finishes, then to coaching.
Stephan combines a data-driven approach with what he learned on his own journey as an amateur athlete. He describes himself as a cheerleader at heart, but firm in approach.
“His line is: “Genetics loads the gun, lifestyle pulls the trigger.””
Why Stephan for North Carolina?
A flat, fast course rewards pacing discipline over raw power, which is exactly where his data-driven approach earns its keep. He knows what a forty-eight-year-old with a full diary can absorb in a June week, because he was one.
The programme: 31 coached weeks to 16 October 2027
Every Wingman race follows the same shape — an optional twelve-week preseason to build the base, then a race-specific programme through to race day.
Stage 01
Optional twelve weeksPreseason
13 March to 4 June 2027
Build your aerobic engine, strength, movement quality, and swim technique from scratch if needed. This is the base-building phase, before intensity increases.
Stage 02
nineteen weeksRace programme
5 June to 16 October 2027
North Carolina-specific: sustained tempo bike work at your tested number, tide-assisted swim sighting practice, run-pace discipline off the bike, and heat-aware training through the late summer before race day.
Stage 03
Race week
11 to 16 October 2027
Taper, travel, a shake-out swim, ride and run with Stephan the day before, a transition walkthrough, and coach support on the course in Wilmington.
The weekly commitment
Preseason runs at roughly five to seven hours a week. The race programme peaks at eight to eleven hours a week, then comes down through the taper. This depends on the athlete's level. The hours mentioned here are a bare minimum. Sessions are built around your actual calendar, not an idealised one.
If you miss a week, the plan adapts. It is rebuilt around what you did, not what you were supposed to do. That is what "adaptive" means here, and it is the difference between a coach and a downloaded PDF. On Team Wingman, the plan is fitted to your week once, at signup. On Wingman Custom and Wingman One, Stephan reviews your training every day and rebuilds the plan with you. How Wingman's online coaching works.

Every plan comes with a finish-or-refund guarantee: if you follow the plan and don't finish, we refund your coaching fees. Minimum compliance requirements apply.
Every plan runs on a six-month initial term, then continues month to month. You can change plans or cancel with 30 days' notice once the initial term is complete.
Our coaching packages cover your training, not your Ironman race ticket. You'll need to buy your race entry separately from the official race organiser.
Eight hours a week, on your terms
You are not going to move to Boulder. You have a business, and children, and a diary that is only partly yours.
Here is what the maths actually looks like. At the peak of the North Carolina programme you are riding twice on weekdays — early, on a turbo, sixty to ninety minutes — running twice, swimming twice, and giving up one long weekend morning. That is it. The long ride that people dread is a Saturday morning, and a flat course means it suits a turbo whenever the weather or the diary says so.
What we do with the weeks that go wrong. They will. You will have a week in August where you travel to three cities and train once. When that happens, you tell Stephan, and the plan is rebuilt — not with a guilt trip, and not by cramming the missed sessions into the following week, which is how people get injured. The programme assumes that roughly one week in six will not go to plan.
North Carolina with the family
Wilmington is one of the easier races on the calendar to bring people to, because the finish line is already a tourist attraction.
Mid-October on the Carolina coast is mild, uncrowded, and a good week to combine a race with a family trip.
Getting there
Wilmington International Airport (ILM) is minutes from downtown, with connections through several major hubs. Raleigh-Durham (RDU) and Myrtle Beach (MYR) are both under two hours by car for travelers who find better fares there.
Where to stay
Wrightsville Beach puts you at the swim start with a beach holiday built in; downtown Wilmington puts you at the finish, walking distance from the Riverfront. Both fill up for race weekend, so book early.
What they do while you race
The Battleship North Carolina Memorial sits across from the finish line. Wrightsville Beach itself is a destination beach town. Downtown Wilmington's historic riverfront has restaurants and shops for the rest of race week, and the North Carolina coast's beaches and marshes are easy day trips either side of the race.

On registration
IRONMAN 70.3 North Carolina has sold out in multiple recent years. Book your race entry with IRONMAN as soon as registration opens, and your accommodation in the same week; we will tell you when.
The genuine deadline is the preseason, not the race. Athletes who join after the preseason starts are compressing 31 weeks into 19, and that is where injuries come from.
Questions people actually ask
How hard is IRONMAN 70.3 North Carolina?
One of the more forgiving courses in the series in terms of terrain: a tide-assisted swim, around 300 to 400 feet of bike climbing over 56 miles, and a flat run. What it asks for is pacing discipline on a course with no hills to force a change of effort, not strength to get over climbs.
Is the IRONMAN 70.3 North Carolina swim wetsuit legal?
Yes, in most years. Water temperature in mid-October typically sits in the upper 60s to low 70s°F, within wetsuit range for the large majority of athletes.
How flat is the North Carolina bike course?
Very. Total climbing over the 56-mile out-and-back through Pender County is around 300 to 400 feet — one of the flattest bike legs on the 70.3 calendar. The road itself is a long, straight highway through pine forest rather than a scenic route.
Is the tide-assisted swim really faster?
Generally, yes. The Banks Channel swim at Wrightsville Beach is timed to run with an incoming tide, which carries athletes along for much of the course and tends to produce faster swim splits than a still-water swim of the same distance.
Does IRONMAN 70.3 North Carolina sell out?
Often. The race has sold out general registration in multiple recent years. Register as soon as entries open and book accommodation the same week.
What is a good time for a first 70.3 at North Carolina?
The flat course and assisted swim make it one of the better venues on the calendar for a personal best, but we don't publish a placeholder number without the race's own finisher data to back it up — your coach will set a specific target after your first testing block.
Can I train for this while running a business?
Yes, and it is most of what we do. Peak weeks run eight to eleven hours: two early turbo rides, two runs, two swims and two long weekend sessions. The flat course suits turbo training when the diary is tight. The programme is built around your calendar and rebuilt when your calendar wins.
I have not trained properly in years. Is 31 weeks enough?
For a 70.3, from a low base, with consistent coached work, yes, and it is the reason the preseason exists. The twelve weeks from March are about building the aerobic base and strength before the specific work starts. Athletes who skip that phase are the ones who get hurt in the summer build.
Where do my family watch?
The run passes through downtown Wilmington and around Greenfield Lake twice, and the finish is at Riverfront Park across from the Battleship North Carolina — a genuine attraction in its own right, not just a finish line.
What happens on the free consultation call?
Twenty minutes with Stephan. Where you are now, honestly. What 16 October 2027 would take. Whether the two of you would work well together. If the answer is no, he will tell you.
Thirty-one weeks from now, this is either a story or a thing you thought about
Preseason starts 13 March 2027. Coach capacity for North Carolina is limited, and the race itself tends to sell out. The call costs nothing and requires no commitment.
