Find a race that supports your goals.

Not all races are created equal, and if you have a time goal, it’s a good idea to choose an event that works in your favor. Look for established half marathons that are well-organized and have USATF-certified, measured courses. The last thing you want to do is end up running on a course that’s too short or too long. Consider the time of year and the weather; if you’ll be training throughout the summer, a warm October race day might not feel too bad. On the other hand, if you train through a cold winter, your body might not be prepared for an unseasonably warm April day. You may also want to pay attention to the course profile and look for a race that doesn’t have a ton of elevation gain.

Plan out your training.

There are as many ways to train for a half marathon as there are runners; some people do better with high mileage while others need more cross-training or speed work. The important thing is to choose a training plan that works with your body and schedule. A few things to look for in a training plan: long runs that reach at least 10 miles, speed work that lets you practice race pace, and appropriate rest days to absorb the training. Generally ~12 weeks is a good amount of time for a half-marathon training block, but pencil in more if you’re new to running. And consider a tune-up race or two; these are shorter races that can give you an idea of where your fitness stands. There are plenty of calculators online that can convert a 5k or 10k time into an equivalent half marathon time. They aren’t perfect, but they can give you an idea if you’re on track or not.

Focus on fueling.

Once you’ve completed your training plan, there’s another important piece: fueling your body for the upcoming race. Depending on your digestive system and experience level, you may want to limit high-fat and high-fiber foods in the days before the race, as they can cause stomach upset. Prioritizing simple carbohydrates (and plenty of them!) ensures your muscle glycogen will be stocked and ready to go when you toe the line. And of course, you’ll want to make sure you’re taking in fuel (i.e., gels, chews, or liquids) during the race, too. Most experts agree that consuming 30–60 grams of carbohydrates per hour helps to avoid “hitting the wall” or running out of gas mid-race.

Create a race plan.

Once you’ve logged your final training runs and dialed in on nutrition, it’s time to create a race strategy. Think about the course logistics, i.e., are there hills or lonely spots during certain miles? Will the weather heat up by the final 5k? Do you tend to go out too fast? Once you know the pain points, you can craft a race plan that will help you finish strong. Starting conservatively and picking up the pace for the second half (this is called a negative split) is an effective strategy for a successful race. A sample race plan might be: 9:10 pace for miles 1–4, 9:05 pace for miles 5–8, 9:00 pace for miles 9–12, and then finish the last mile with whatever you have left.

Finishing a half under two hours isn’t always easy, but if you stick to a training plan and follow these tips, the odds will be in your favor.

Frequently Asked Questions

What pace do I need to run a sub-2:00 half marathon?/h3>

To finish a half marathon in under two hours, you need to maintain an average pace of approximately 9:05 per mile (or about 5:39 per kilometer) across all 13.1 miles. Building in a slight buffer by targeting 9:00–9:05 per mile in training will give you a margin for hills, crowded start corrals, or any rough patches mid-race.

How many weeks should I train for a sub-2:00 half marathon?/h3>

Around 12 weeks is a solid training block for most runners targeting this goal. If you’re newer to running or building up your mileage base, giving yourself 16 weeks or more is a smart move. The extra time allows for gradual mileage progression without overloading your body too quickly.

What should I eat before a half marathon?/h3>

In the days leading up to the race, prioritize simple carbohydrates and limit high-fat, high-fiber foods that can cause digestive upset. On race morning, a light, carbohydrate-rich meal two to three hours before the start — such as toast with peanut butter and a banana — works well for most runners. Stick with foods you’ve tested during training rather than trying anything new on race day.

Do I need to take gels or fuel during a half marathon?/h3>

For most runners targeting a sub-2:00 finish, yes. Most experts recommend consuming 30–60 grams of carbohydrates per hour during a race, which typically means taking in one to two gels or the equivalent in chews or sports drink per hour. Practice your fueling strategy during long training runs so your stomach is prepared for race day.

What is a negative split and should I use that strategy?/h3>

A negative split means running the second half of the race faster than the first. It’s one of the most effective pacing strategies for a strong finish because it keeps you from going out too hard early and fading late. Starting 10–15 seconds per mile slower than goal pace in the first few miles and gradually building through the back half gives your body time to warm up and preserves energy for a strong close.
