Patriot Half training plan and course guide.
The Patriot Half is one of New England's longest-running 70.3-distance races and a common A-race for Boston-area triathletes. This is a 24-week build calibrated to the course, the early-June water temperature, and the typical race-day weather window — written by a 4× IRONMAN World Championship qualifier and IRONMAN 70.3 champion.
The course, leg by leg
1.2 mi in a freshwater pond. Predictable water, manageable for first-timers in a wetsuit. Sighting is straightforward off the buoy line; the early sun angle can be tricky on the back stretch.
Flat to rolling on rural roads through cranberry bog country. Net-flat profile but wind-exposed. Hold low end of race power — first-timers tend to overcook the first 20 miles and pay for it on the run.
Two loops through Freetown State Forest. Mostly flat with a few short rollers. Aid stations roughly every mile. Mid-June heat is the variable — pacing must respect dew point, not clock pace.
24-week plan structure
Aerobic build across all three sports. Swim CSS testing, FTP test on the bike, easy-pace run progression. Twenty hours total per week is not the goal — consistency is.
Race-pace bricks introduced. First 60-mile rides. Open-water sessions begin at Walden once water is over 60°F. Strength block runs in parallel two days a week.
Race-rehearsal long days — 70-mile ride + 6-mile brick run at race effort. Nutrition strategy locked in. Bike-fit confirmed. Two race-pace 90-min trainer sessions per week.
Highest volume week ~14 hours. Race simulation 4 weeks out: 1500yd swim → 56-mi ride → 10-mi run. Final FTP and CSS tests inform race-day pacing zones.
Volume drops, intensity stays. Carb load calibrated to body weight. Hydration and sodium dialled. Course recon if logistics allow. Race-morning protocol rehearsed in the final long brick.
Race-week protocol
- Carb load: 8–10 g/kg body weight across 36–48 h pre-race
- Hydration: pre-load sodium 24h out, target 600–900 mg/L race-day
- Bike: 15-min spin Saturday, gear shakedown, tire pressure dialled
- Swim: short shakeout in Long Pond Saturday if open
- Nutrition: 70–90 g carbs/hour on the bike, switch to liquid + gels on the run
- Pacing: bike at 70–75% FTP for first-timers, 78–82% for experienced age-groupers
- Run: 6–10 bpm under threshold HR for the first 4 miles, then race
- Heat plan: dew-point-adjusted pace, ice at every aid station above 65°F dew point
Frequently asked questions
When is the Patriot Half?
The Patriot Half is held in mid-June in Freetown, Massachusetts. It's one of New England's longest-running 70.3-distance races and a popular early-season half-IRONMAN for Boston-area triathletes.
How hard is the Patriot Half bike course?
It's flat to rolling — fast on paper, but exposed to wind across the cranberry-bog terrain. Strong age-groupers can hold near-FTP power numbers; first-timers should pace conservatively and save legs for the run.
How long should I train for Patriot Half?
Twenty-four weeks for first-timers from a swim-bike-run base. Sixteen to eighteen weeks for experienced triathletes coming off a winter run cycle. The mid-June date means a base block through the New England winter on the trainer.
Do you coach for Patriot Half specifically?
Yes — Patriot Half is one of the most common A-races on the roster because so many of my athletes are Boston-based. The build is calibrated to the course, the early-June water temperature, and the typical race-day weather window.
What is the Patriot Half swim like?
A 1.2-mile freshwater swim in Long Pond. Predictable water, manageable for first-timers in a wetsuit. Sighting is straightforward off the buoy line; the early sun angle can be tricky on the back stretch. Water temperature is usually wetsuit-legal in mid-June.
Is the Patriot Half good for first-time 70.3 athletes?
Yes — the flat-to-rolling bike and the two-loop run through Freetown State Forest make it approachable. The freshwater swim is less intimidating than ocean swims. The main challenge is mid-June heat and humidity, which we address with dew-point-adjusted pacing and heat-acclimation training.
What should I eat during the Patriot Half?
On the bike: 70–90 g carbs per hour from a mix of drink mix, gels, and solid food if tolerated. On the run: switch to liquid and gels only. Sodium: 600–900 mg/L based on your sweat test. Practice your exact race fuelling in training bricks — never try something new on race day.
