In 2025, More than 142 thousand athletes Race at least one Ironman 70.3. This does not include those who participate in local, unbranded races.
Unfortunately, just under 135,000 of these athletes finished the race. The right training and nutrition plan can help athletes avoid being part of the nearly 5% of athletes who play sports. DNF (do not expire) It happened.
We’ve compiled the best 70.3 training plans, nutrition guides, and race recommendations to guide you to your strongest result yet. Prepare well and enjoy the process with expert guidance that trumps any response AI can conjure.
70.3 Training plans from beginner to advanced
As you work your way up to a middle-distance triathlon, training for three sports will take longer and getting adequate rest and recovery will be more difficult.
For this reason, it’s wise to use an expert-led training plan to help you get to the finish line with as little risk of injury and fatigue as possible. Whether you’re new to distance running or looking to improve your past times, there’s a training plan tailored to your unique needs.
For the first timer, here’s the perfect 70.3 training plan
Ideally, you’re landing here long before your 70.3 race because this training plan from coach Matt Fitzgerald is designed to be 20 weeks long. Yes, it’s a big commitment, but that’s what I signed up for with the half-iron distance.
The plan consists of four phases: base, build, peak, and taper – each expertly designed to get you race day fit, healthy, and mentally and physically prepared for the long day ahead.
With a difficulty level of one, the plan is designed for true beginners looking to make the most of their first finish line of 70.3.
70.3 Intermediate training plan for established athletes and those looking for a PR
If you’ve been triathloning for years, and have completed a lot of Olympic distance races, or even a few 70.3 events, this is your training plan.
The training load is a little heavier and more intense than you’ll find on a beginner’s plan but it’s still very achievable for triathletes who have seen some finish lines and know the determination it takes to get there.
The 16-week training plan starts with approximately nine hours of training and peaks at 15 hours and 30 minutes in week eight with ample strategy around honing your skills and tapering off.
Advanced 70.3 training plan for your best time yet
Whether you’re targeting the sub-6 or sub-5 70.3 hours, this advanced training plan will help you get there. The work is intense, but the payoff is worth it.
Triathlon coach Matt Fitzgerald guides athletes through 20 weeks of targeted training with an eight-week base phase, a six-week building phase, and a six-week peak phase with intentional workouts designed to make you stronger while building your endurance.
Cross the 70.3 finish line in 5:59:59 or less
Breaking the 6-hour mark is a goal for many 70.3 athletes. To achieve this goal, you need more than just a standard training plan. You need one that helps you build the right speed to achieve your goals.
This less than 6-hour 70.3 training plan focuses on speed, setting you up for success through seven weeks of training to achieve your time-based goal. But with such a short training period, this is for triathletes who already have the endurance and fitness to get to the finish line, but are not yet in time for their goal.
Professional triathlon coach hits the road to a best 70.3 in an online course
You’ve got your training plan taped to your fridge, uploaded to TrainingPeaks, and at the top of your day, every day. But learning why that is can help you get the most out of every training session as you prepare for the mental game of race day.
Professional triathlon coach Jim Vance walks outside + members By finding a baseline for their performance, developing open water swimming skills for a more comfortable swim, fattening up race day nutrition, tapering well, and important race day logistics.
Stop fading while running with this six-week running-focused training plan
By the time you reach a 70.3 race, your body will have undergone a few hours of fatigue. It’s common for triathletes to fade in the final miles of a race, which can be frustrating after an excellent performance.
But with the right running-focused training plan, you can stop the fade and finish strong. We tasked triathlon coach Scott DeFilippis of 15 years with creating a plan that doesn’t pause cycling or swimming, but focuses on building enough endurance and fitness to maintain a steady running pace even when fatigue sets in.
Get 70.3 nutrients in training and on race day
Keep doing triathlon long enough, and you’ll start to hear about the fourth system: nutrition. Do it right, and you’ll feel great all the way to the finish line. If you skimp on nutrition or eat the wrong food, you risk vomiting your guts out or burning out late in the race.
Testing nutrition plans, finding products your stomach welcomes, and getting your hourly carb count right based on your unique physiology are all part of training for the 70.3 race. Our experts explain how to do it effectively.

Choosing the appropriate race 70.3
Maybe your goal is to see a part of the world you’ve never seen before while enjoying the racing spectacle. Or you may want to sleep in your own bed the night before your first 70.3 race. Regardless, we have race recommendations to guide you in making the smart choice that’s right for you.
Can (and should you) do 70.3 as your first triathlon?
You’ve set your sights high and are ready to jump right into the sport with a 70.3. But the bigger question is: Should you start there, or race in some shorter events first to get familiar with the sport?
Quite frankly, it’s a question you can only answer based on your goals for the 70.3 race, your experience with endurance racing in general, the time you can realistically commit to training, and the amount of time you have before your big race.
In an ideal scenario, you would do a shorter-distance tune-up race to get used to the sport and handle traffic on the track. But triathlon coach Alison Freeman shows how to run a race simulation to help you prepare if a controlled race isn’t possible.

Choose your race based on pace (backed by a triathlon data expert)
