Don Fink Half Ironman Training Plan Download
Overview and Training Philosophy for Don Fink Half Ironman
Training for a Half Ironman (Ironman 70.3) requires a disciplined approach that balances volume, intensity, recovery, and race-specific demands. The Don Fink training philosophy emphasizes a clear periodization framework, purposeful hard sessions, and strategic recovery to maximize endurance while minimizing injury risk. This section provides the foundation: the why behind the plan, the expected outcomes, and how to adapt the framework to your current fitness, schedule, and goals. Don Fink’s method centers on four pillars: progressive overload, specificity to race distance, sustainable consistency, and intelligent tapering. By following these principles, athletes commonly improve swim efficiency, bike endurance at target paces, and run resilience off the bike. Real-world data show that a well-structured Half Ironman plan can yield 10–20% improvements in race-day endurance markers over a 12–20 week window, with fewer injuries when volumes align with ability and recovery is prioritized. Every plan download includes a baseline assessment, a phased progression (Base → Build → Peak → Taper), and a weekly rhythm designed to fit most schedules. The plan also accounts for course profiles (flat vs hilly), equipment (performance-oriented wetsuit, bike fit), and personal constraints (work, family, travel). The intent is not to “cram” miles but to cultivate steady gains in swim technique, bike efficiency, and running economy while ensuring you arrive at race week rested and confident. Expect a few weeks of higher consistency, then a deliberate ramp of intensity, before a taper that preserves fitness while reducing fatigue. The approach places strong emphasis on brick workouts, race-specific paces, and nutrition integration, so your body learns to sustain effort across three disciplines without abrupt fatigue. In practice, you will see structured blocks that help you move from technique and aerobic base to tempo and threshold work, then to race-specific bricks and finally a taper. The plan includes guidance on session duration, target intensities, pacing strategies, and when to substitute sessions due to life events or minor injuries. Real-world applications include adjusting long-ride durations to reflect terrain, altering swim sets to address technique gaps, and using run off the bike to simulate race-day fatigue. This framework is scalable, adaptable, and designed to deliver a confident, well-prepared performance on race day.
Baseline Assessment and Goal Setting
Before you embark on any training cycle, establish a clear baseline and realistic goals. This ensures you train with intention and track meaningful progress. Baseline testing identifies your current endurance, technique inefficiencies, and recovery tolerance. For a Half Ironman, practical baseline metrics include: a 1.2-mile swim time or 1,900-yard swim time, a functional threshold power (FTP) or steady-state power on the bike, and a recent 5K or 10K run time. If power metrics are not available, use heart-rate reserve and pace-based targets to quantify intensity bands. Data collection should be consistent: same pool, same course, same bike and run surfaces if possible. Key steps for baseline assessment:
- Swim: Perform a controlled 1,200–1,600 meter swim with 50–60 seconds rest between sets; record pace per 100m and stroke rate. Include technique drills (catch, arm extension, layout) to identify efficiency gaps.
- Bike: Complete a 20–40 minute tempo ride with a consistent cadence and power if possible; determine a sustainable average power and optimize pedal stroke. If you lack power data, track average cadence and heart rate at a steady effort.
- Run: Do a 5K time trial or a 20-minute tempo run to establish pace bands and running economy after cycling fatigue.
- Swim: Improve efficiency by 10–20% (e.g., from 1:50/100m to 1:40/100m in a pool test).
- Bike: Increase FTP by 5–15% or sustain a 70–75% of FTP for 60–90 minutes with minimal cadence drift.
- Run: Achieve a steady pace that feels sustainable for 60–75 minutes after cycling, or improve 5K run time by 5–10% while maintaining form.
Periodization, Weekly Structure, and Block Design
Periodization organizes training into phases that optimize performance while minimizing overuse injuries. The typical Don Fink-inspired framework uses four phases: Base, Build, Peak, and Taper. Each phase has a distinct focus, weekly structure, and progression. You will see a steady shift from high-volume, lower-intensity work to increased intensity and skill-specific tasks, followed by a race-week taper that preserves fitness while reducing fatigue. The weekly structure is designed to balance swim, bike, and run sessions with recovery and sleep, enabling durable adaptation. A standard 6- to 10-hour weekly window is common for athletes with full-time jobs, while 10–14 hours can be appropriate for those with more training history or flexible schedules. The key is consistency and quality of sessions over sheer volume. Base Phase (8–12 weeks): build aerobic capacity and technique. Expect longer, low-intensity workouts with a few technique-focused swims and bricks. Build Phase (6–8 weeks): introduce tempo and race-pace work, longer bricks, and moderate-intensity blocks to improve fatigue resistance. Peak Phase (2–4 weeks): sharpen intensity, practice fueling, and refine transitions. Taper (1–2 weeks): reduce volume by 30–50% while maintaining intensity to preserve neuromuscular science and race readiness. The weekly template typically includes 2–3 swims, 2–3 bikes, and 2–3 runs, with one brick session and at least one full rest day each week. Use of low-intensity aerobic sessions for recovery and high-intensity blocks for adaptation is a hallmark of the plan. Concrete weekly templates offer a practical starting point. For example, a mid-cycle week might look like this: a swim with technique sets in the morning, a bike workout that includes 2 x 20 minutes at tempo with 5 minutes recovery, a run of 40–60 minutes with 2 large thresholds, and a brick run of 15–20 minutes after a shorter bike ride. Long sessions emphasize endurance, with a 2.5–4 hour ride on weekends and a 60–90 minute brick run to simulate race-day fatigue. Recovery days incorporate mobility work, light swimming, or easy cycling to promote adaptation without overloading joints. Visualizing your week as a balanced mix of low, moderate, and high intensity helps you avoid mental and physical burnout while facilitating steady gains. In this Don Fink framework, pacing guidance and intensity zones evolve with the phase. Early blocks emphasize technique and efficiency, while later blocks push you toward race-specific tempos and thresholds. Periodization is your compass for adjusting training when life events interrupt cycles, preserving momentum and reducing injury risk. You should also maintain a flexible mindset: while structure is vital, the plan rewards consistency and willingness to adapt to your body’s signals and external commitments.
Sport-Specific Training: Swim, Bike, Run and Brick Sessions
Sport-specific training focuses on translating general endurance into the unique demands of a Half Ironman. Each discipline requires technique, pacing, and race-day integration of fueling and transitions. A well-rounded plan emphasizes technique refinement, aerobic capacity, and the ability to sustain effort across three disciplines with minimal performance decline. You will work on swim efficiency, bike economy, and run speed, while brick sessions train your body to transition smoothly from cycling to running. You should also incorporate open-water practice if your race includes a wetsuit swim or if open-water conditions differ from pool settings. Real-world metrics show that participants who include regular bricks and brick-pacing workouts improve run splits by 5–10% versus those who only train in isolated disciplines. Swim Training (4–6 sessions per week during Build/Peak): include a mix of technique drills (catch, breath control, body position), steady 200–300m repeats with short rests, and longer 400–800m sets with controlled stroke rate. Open-water practice is vital for navigation, sighting, and mental comfort. Run times may be inconsistent at first due to fatigue, so swims should be deliberately paced to prevent early fatigue while enabling your long-term technique development. Drills like fingertip drag, zipper drill, and sculling help improve efficiency and speed at the front of the stroke, while pacing strategies help you settle into a sustainable rhythm on race day. Bike and Run Modules (4–6 weekly): structure intervals to build both endurance and threshold. Tempo rides of 60–90 minutes at 70–85% of FTP or race-pace can improve sustained power, while longer intervals (2–4 x 15–20 minutes) at threshold push your ability to hold your target pace. Run sessions should alternate between easy aerobic runs, tempo intervals, and run-offs from cycling to develop leg turnover and fatigue resistance. Brick workouts—cycling followed immediately by running—simulate race-day fatigue and teach you how to transition with efficiency. A typical brick might be 60–90 minutes on the bike followed by 15–20 minutes of running at a comfortable, sustainable pace. Injury prevention and technique refinement are woven throughout these sessions. Proper warm-ups, mobility work, and attention to form help reduce injury risk during high-volume blocks. If you experience persistent pain, adjust volume and consult a professional to address mechanics or equipment fit (bike fit, running shoes, or wetsuit selection). The ultimate aim is to produce a smooth, economical performance across all three disciplines on race day, with a pace plan that aligns with your fitness and fueling strategy.
Nutrition, Recovery, and Injury Prevention
Nutrition and recovery are inseparable from performance. Endurance athletes rely on precise fueling strategies to sustain energy, promote recovery, and prevent gastrointestinal distress during long sessions. A practical plan uses carbohydrate-centric fueling (3–5 g/kg body weight per day on training days, higher on heavy training days), adequate protein (1.2–1.6 g/kg for recovery and adaptation), and healthy fats to support hormonal balance and joint health. On long workouts and race days, fueling windows typically include 30–60 grams of carbohydrate per hour from sources such as gels, hydration, or sports drinks. Hydration strategy should consider electrolyte loss, especially in warm conditions; many athletes use 600–1200 mg of sodium per liter of fluid depending on sweating rate. Practice fueling during training to identify what sits best with your stomach and energy levels. Recovery strategies include quality sleep (7–9 hours per night for most adults), structured rest days, mobility work (15–20 minutes), and easy aerobic sessions that promote blood flow without adding fatigue. Sleep and nutrition interact closely with recovery; inadequate sleep reduces hormone balance and increases recovery time. Injury prevention emphasizes gradual progression, strength and conditioning work, and listening to early warning signs like persistent joint stiffness or sharp pain. A robust plan includes 1–2 strength sessions weekly to build trunk and leg strength, core stability, and joint resilience. Mobility routines and post-training cooldowns support flexibility and reduce stiffness, facilitating faster adaptation to training loads. Race-week strategy includes a slightly reduced training load, a focus on fueling consistency, and a mental rehearsal of your race-day plan. Tapering reduces fatigue while preserving fitness, allowing you to feel fresh on race day. The nutrition plan during taper emphasizes grocery and meal planning to avoid GI surprises and ensure you arrive at the start line with well-stocked glycogen stores and a comfortable hydration balance. All athletes should tailor nutrition to their body. Use trial runs to confirm tolerance to pre-race meals and race-day fluids, and practice refueling during long bricks to prevent energy dips during the run segment.
Monitoring, Adjustments, and Race Day Strategy
Progress monitoring ensures your plan remains effective and adaptable. Record training loads, pace, heart rate, and perceived exertion (RPE) after each session. Tools such as Training Impulse (TSS), chronic training load, and pacing charts help identify trends and early signs of overreaching. If you notice a plateau or plateau-like fatigue, adjust by reducing intensity or volume, incorporate extra rest days, or shift to lower-impact workouts to allow full recovery. Interviews with athletes reveal that timely adjustments prevent burnout and support sustainable progress across a multi-month training cycle. In race preparation, finalize your race-day plan: open-water or pool swim approach, drafting strategies on the bike, and run pacing at the point of transition. Ensure your fueling plan aligns with practice sessions and is robust under heat or humidity. Practice transitions (T1 and T2) multiple times in bricks to reduce the time spent in transition. Race-day tactics include starting conservatively, gradually increasing effort, and finishing with a controlled yet decisive push in the final 1–2 miles. A well-executed nutrition plan, combined with disciplined pacing and transition strategy, yields consistent performance gains and a more enjoyable race experience.

Frequently Asked Questions
Q1: Is this plan suitable for absolute beginners?
A beginner-friendly version can be created by reducing volume and intensity, focusing on technique in all three disciplines, and extending the Base phase to build a solid aerobic foundation. Begin with two swims per week, two bikes, and one run, with ample rest and mobility work. Gradually increase sessions as technique improves and endurance increases. If you are new to triathlon, consider a longer timeframe (28–30 weeks) to minimize injury risk while adapting to the multi-sport demands.
Q2: How do I choose the right week-to-week intensity?
Intensity should be anchored to your current fitness and baseline metrics. Use heart-rate zones or pace bands, and if you have a power meter, target specific zones for bike sessions (e.g., zones 2–3 for base, zone 3–4 for tempo, and short bursts in zone 5 for race-pace surges). Beginners should spend more time in zones 1–2 to build aerobic capacity, then progressively introduce tempo and threshold work as technique and endurance improve.
Q3: How should I adjust if I miss a workout?
Missed sessions should be remapped into the plan without doubling up on fatigue. For example, replace a missed high-intensity session with a lighter alternative (low-volume, low-intensity) and shift other sessions by a day or two. If several days are missed, re-evaluate the plan’s progression to ensure appropriate recovery and avoid overtraining. The goal is to maintain consistency over time while avoiding abrupt spikes in load.
Q4: What are the most important bricks for half-iron training?
Bricks train your body to run well off the bike and are crucial for triathlon performance. Focus on bike-to-run transitions with runs of 15–30 minutes immediately after cycles of 60–90 minutes at race-pace effort. Brick sessions help your legs adapt to fatigue and improve run form as you exit the bike, which significantly affects overall race time. Bricks also provide a practical test of fueling strategies under fatigue.
Q5: How should I approach nutrition during training?
Practice fueling during long workouts to identify tolerance and stomach comfort. A typical strategy includes 30–60 grams of carbohydrate per hour on long sessions, with fluids containing electrolytes to replace sodium losses. Adjust hydration for climate; hotter conditions require higher fluid intake and more electrolytes. Protein intake post-workout (20–40 grams within 30–60 minutes) supports muscle recovery. Test different products during training to find what works best for your stomach and energy needs.
Q6: How often should I test my baseline metrics?
Baseline tests can be repeated every 6–8 weeks to monitor progress and adjust targets. For athletes aiming at a peak in Week 20–24, schedule a mid-cycle check to gauge improvements in efficiency (swim technique, bike pacing, run form) and adjust training loads accordingly. Frequent testing should not induce additional fatigue; keep tests focused and short, and ensure adequate recovery after each test.
Q7: Can I customize this plan for a hilly course?
Yes. Modify long rides to include hill repeats and simulate elevation gain. For runs, incorporate uphill tempo segments to prepare for climb demands. In the swim, consider drafting strategies near current course sections if water is crowded or choppy. Tailor pacing to course profile and practice fueling on climbs and at high-output efforts to ensure you stay consistent through the run segment.
