3. Prioritize Long Runs
Long runs are the cornerstone of marathon training. They help build endurance, teach your body to burn fat efficiently, and prepare you mentally for the distance. Gradually increase your long run distance each week, peaking at 32-35 km about three weeks before the race.
4. Incorporate Speed Work
Speed work, such as intervals and tempo runs, improves your running economy and helps you maintain a faster pace on race day. Include one speed session per week, alternating between intervals, tempo runs, and hill repeats.
5. Don’t Neglect Recovery
Recovery is just as important as training. Schedule at least one rest day per week and consider incorporating active recovery activities like yoga, stretching, or light cycling. Listen to your body and take extra rest if you feel fatigued or notice any signs of injury.

Nutrition and Hydration for Marathon Training
1. Fuel Your Runs
Proper nutrition is critical for marathon training. Focus on a balanced diet rich in carbohydrates, lean proteins, healthy fats, and plenty of fruits and vegetables. Carbohydrates are especially important for long runs, as they provide the energy your muscles need to perform.
- Pre-Run: Eat a light meal or snack 1-2 hours before your run. Opt for easily digestible carbs like a banana, toast with peanut butter, or oatmeal.
- During the Run: For runs longer than 90 minutes, consume 30-60 grams of carbohydrates per hour. Energy gels, chews, or sports drinks are convenient options.
- Post-Run: Refuel within 30-60 minutes after your run with a mix of carbs and protein, such as a smoothie, yogurt with fruit, or a balanced meal.
2. Stay Hydrated
Hydration is key to maintaining performance and preventing fatigue. Drink water throughout the day and during your runs, especially in Borneo’s tropical climate. For long runs, consider carrying a hydration pack or planning routes with water fountains.

Race Day Strategies
1. Arrive Early
On race day, arrive at the venue at least 1.5-2 hours before the start time. This will give you enough time to park, pick up your race bib (if not done earlier), warm up, and use the restroom.
2. Warm-Up Properly
Spend 10-15 minutes doing dynamic stretches and a light jog to prepare your muscles for the race. Avoid static stretching before running, as it can reduce muscle power.
3. Start Slow
It’s easy to get caught up in the excitement and start too fast. Stick to your planned pace, especially in the first half of the race. Conserving energy early on will help you finish strong.
4. Use Aid Stations Wisely
Take advantage of the water and fuel stations along the course. Practice your hydration and fueling strategy during training to avoid stomach issues on race day.
5. Stay Mentally Strong
The full marathon distance is as much a mental challenge as it is a physical one. Break the race into smaller segments, focus on your breathing, and use positive self-talk to stay motivated.

Post-Race Recovery
After crossing the finish line, prioritize recovery to help your body bounce back:
- Cool Down: Walk for 10-15 minutes to gradually lower your heart rate.
- Refuel: Eat a balanced meal or snack within an hour after the race to replenish glycogen stores and aid muscle repair.
- Rest: Take a few days off from running to allow your body to recover. Light activities like walking or swimming can help with circulation and reduce soreness.

Final Thoughts
Conquering the full marathon distance at the Borneo International Marathon 2025 is a challenging but achievable goal with the right preparation.
