Step 1: Assess your current running pace and fitness
Before you can build a realistic pacing strategy for the May 2026 half marathon, you need to understand exactly where you stand right now. This isn’t about judging yourself. It’s about gathering honest data so your training plan makes sense for your body and your goals.
Start by running at a comfortable, sustainable pace for about 20 to 30 minutes. This should feel like you could hold a conversation, but you’re breathing a bit harder than normal. Check your time and distance. If you use a running watch or app, note your average pace per kilometre. If you don’t have a device handy, self-reported running pace measurements can give you reliable data for training purposes, so keep a simple note in your phone or notebook.
Now assess your aerobic fitness by testing how you feel during this effort. Could you push harder? Did you feel controlled and strong? Your aerobic and anaerobic energy contributions directly shape your race pacing capacity. Run the same route or distance at least twice over the next week. Consistent measurements help you spot real improvements rather than one-off variations. This baseline becomes your anchor point for everything that follows.
Honesty matters here. If you’re currently running 6 minutes per kilometre comfortably, that’s your starting pace. Not the pace you wish you ran, or the pace your friend runs. Your actual pace. This foundation prevents you from setting pacing targets that feel impossible during training, which kills motivation quickly.
Think about how your body felt during these test runs too. Did your legs feel heavy? Were you breathing heavily but not gasping? Did your mind wander or did you focus on every step? These clues tell you whether fitness issues are strength-based, endurance-based, or mental. Understanding the difference shapes which training sessions matter most.
Pro tip Record your baseline pace, distance, and how you felt after each run in a spreadsheet or training app, then repeat this assessment every three to four weeks to track genuine fitness progress rather than daily fluctuations.
Step 2: Set a realistic half marathon target time
With your baseline fitness established, you can now set a goal time that actually motivates you rather than demoralises you. The key is anchoring your target to your current abilities, not some distant fantasy version of yourself.
Start by looking at your recent training data. If you completed that 20 to 30 minute test run at 6 minutes per kilometre, you have a solid starting point. From here, realistic goal paces should build on your actual performance rather than wishful thinking. Many runners make the mistake of setting a target pace that feels exciting but impossible during weekly training. This creates frustration quickly.
Consider your experience level too. If you are relatively new to running, aiming to simply finish strong and enjoy the experience makes complete sense. Experienced runners can push harder and chase specific times. Either way, selecting a realistic target time means your training sessions feel challenging but achievable rather than constantly leaving you feeling defeated.
Now do the maths. A half marathon is 21.1 kilometres. If your comfortable pace is 6 minutes per kilometre, a realistic target sits around 2 hours and 6 minutes. Want to go faster? Brilliant. But drop your pace by only 15 to 30 seconds per kilometre initially. This gives you something to work towards without setting yourself up for disappointment. As your fitness improves over the coming months, you can revise this upwards.
Test your goal pace during one of your weekly runs. Run just 2 to 3 kilometres at your target race pace and see how it feels. Can you sustain it comfortably? Does your breathing stay controlled? If it feels brutally hard, your target pace is too quick. Adjust downwards without shame. A realistic goal that you smash feels infinitely better than an ambitious one you struggle with.
Pro tip Write your goal time somewhere visible like your phone lock screen or bathroom mirror, then run one session each week at your target race pace to build confidence that it is genuinely achievable by May 2026.
Step 3: Design your ideal pacing strategy for race day
Now that you have a target time and understand your current fitness, you need a concrete strategy for how you’ll run those 21.1 kilometres on race day. A solid pacing plan is the difference between executing your goal smoothly and hitting the wall at kilometre 15.
Divide the half marathon into three distinct phases. Start conservatively for the first 7 kilometres. This sounds counterintuitive when you feel fresh, but holding back slightly allows your body to settle into the effort and your nervous system to relax. Many runners blast out too fast simply because the atmosphere and adrenaline feel incredible. Save that energy. You’ll need it later.
The middle phase from kilometres 7 to 16 is where you find your rhythm and hold your target pace. This is your sweet spot. Pacing strategies during the middle section rely on sustaining effort rather than chasing splits, which keeps you mentally engaged and physically controlled. Focus on how your body feels rather than obsessing over your watch. Can you still breathe steadily? Are your legs responding or feeling heavy? These sensations matter more than hitting exactly 6 minutes per kilometre every single time.
The final 5 kilometres test your mental toughness and your fitness gains. This is where your training shines. If you’ve been consistent with your sessions, you have fuel in the tank to push harder. Not recklessly, but enough to give yourself a genuine finishing kick. Many runners achieve their personal bests by running negative splits, meaning they finish faster than they started.
Practise this three phase structure during your longer training runs. Run a 14 kilometre effort and deliberately execute the same pacing pattern. Start easy, settle into goal pace for the middle section, then push the final stretch. Repeating this teaches your body and brain exactly what to expect on race day.
Pro tip Memorise your target pace but also train your legs to recognise how that pace feels so you can run by perceived effort on race day, making adjustments based on conditions rather than panicking if your watch shows a few seconds off target.
Compare how the three pacing phases affect your race performance:
| Phase | Focus Area | Risk if Ignored |
|---|---|---|
| Start (0-7 km) | Energy conservation | Early fatigue |
| Middle (7-16 km) | Settling into rhythm | Drifting off target pace |
| Finish (16.1-21.1 km) | Strong, controlled push | Inability to finish strongly |
Step 4: Implement structured training sessions and simulations
Your pacing strategy only works if your body is prepared to execute it. This is where structured training comes in. Rather than just running whenever you feel like it, you need a deliberate mix of different session types that build the aerobic and anaerobic systems required for half marathon success.
A 12 week structured training plan progresses through specific phases. Base building comes first, where you establish your aerobic foundation with easy runs and longer efforts. Then you move into strength and speed phases that include tempo work and intervals. Finally, you transition into race preparation where everything comes together. Each phase builds on the last, creating a logical progression rather than random workouts.
Incorporate tempo runs into your weekly routine. These are sustained efforts performed slightly faster than your goal race pace, typically for 20 to 30 minutes. A tempo run trains your aerobic system to sustain faster speeds, making your actual race pace feel controlled by comparison. Run these at effort level 7 out of 10, not all out.
Interval sessions and mile repeats push your anaerobic capacity and teach your body to handle faster running. Do 6 to 8 repetitions of 800 metres to 1 kilometre at your race pace or slightly quicker, with recovery jogs between efforts. This trains your system to recover between hard efforts, which matters when you’re pushing in the final kilometres of your race.
Once every three weeks, run a simulation. Execute a 12 to 14 kilometre run at your exact race pace using your three phase pacing strategy. Start easy, settle into goal pace, and finish strong. Treat it like race day with the same breakfast, same kit, and same mental approach. Simulations build genuine confidence because your body knows it can sustain this effort.
Pro tip Schedule your longest run and race simulations for the same day of the week you’ll race, ideally at the same time of day, so your body adapts to performing at peak hours.
Here’s how different types of training runs contribute to half marathon readiness:
| Training Run Type | Main Benefit | Recommended Frequency |
|---|---|---|
| Easy run | Builds aerobic base | 2-3 times per week |
| Tempo run | Improves speed & endurance | Once per week |
| Interval session | Increases anaerobic power | Once per week |
| Long run/simulation | Tests race strategy & stamina | Every 2-3 weeks |
Step 5: Monitor progress and refine pacing approach
Training is not a fixed path. As the months progress towards May 2026, your fitness changes and your pacing strategy needs to evolve with it. Regular monitoring of your progress tells you what’s working and where adjustments are needed.
Track your training load consistently. Every run should be recorded with distance, time, pace, and how you felt. Over weeks and months, patterns emerge. If your tempo runs feel easier, your aerobic fitness is improving. If your goal race pace suddenly feels sustainable when it once felt hard, you have tangible evidence of progress. Monitoring training load through wearable technology helps confirm that your training intensity and recovery are balanced, preventing the burnout that derails many runners.
Every three to four weeks, review your data. Look at your pace trends across different session types. Are your easy runs actually easy, or are you running them too fast? Are your tempo runs improving? Check your longest run. If you completed 14 kilometres at goal pace comfortably six weeks ago and now it feels controlled, you can confidently run slightly faster on race day.
Adjusting pacing based on training feedback is essential for avoiding early burnout and refining your race strategy. If your target race pace now feels too conservative based on recent sessions, you can increase it slightly. Conversely, if sessions are consistently harder than expected, stick with your original target or even reduce it slightly. There’s no shame in honest adjustment.
Pay attention to how your body responds to training. Persistent heaviness in your legs, trouble sleeping, or elevated resting heart rate all signal that you need recovery weeks. These occur roughly every fourth week. During recovery weeks, reduce your mileage by 30 to 40 percent. This allows your body to adapt to training stress and emerge stronger.
Two weeks before race day, stop introducing new workouts. Your fitness is set. Trust your training and focus on staying fresh and managing nerves.
Pro tip Create a simple spreadsheet with weekly average pace across easy runs, tempo efforts, and goal pace sessions, then plot these over time to visualise fitness gains and spot patterns that inform pacing decisions.

Frequently Asked Questions
How do I assess my current running pace for half marathon training?
To assess your current running pace, run comfortably for 20 to 30 minutes at a pace where you can still hold a conversation. Record your time and distance to calculate your average pace per kilometre, which will serve as your baseline for training.
What is a realistic target time for my half marathon?
A realistic target time should be based on your current pace; for example, if your comfortable pace is 6 minutes per kilometre, aim for a target around 2 hours and 6 minutes. Adjust your target pace gradually, only lowering by 15 to 30 seconds per kilometre to avoid setting unattainable goals.
How should I structure my training sessions for a half marathon?
Structure your training sessions to include a mix of easy runs, tempo runs, interval sessions, and long runs. Aim to include each type of run weekly, with long runs every 2-3 weeks to build stamina and practice your pacing strategy.
What should I do if my training paces start to feel too easy?
If your training paces begin to feel manageable, it’s time to reassess your goal pace. Test your target pace during training, and if it feels comfortable after several weeks, consider increasing your pace by about 5 to 10 seconds per kilometre.
How can I monitor my progress towards my half marathon goal?
Monitor your training progress by keeping a record of distance, time, pace, and how you felt after each run. Review this data every three to four weeks to identify patterns in your fitness and adjust your training accordingly.
When should I stop introducing new workouts before the race?
Two weeks before race day, focus on maintaining your fitness by sticking to your established routine. Avoid introducing any new workouts to ensure your body is well-prepared and fresh for the half marathon.
