The long run is the cornerstone for success in the half marathon, but we sometimes don’t give it the attention it deserves. Let’s reassess how you’re running your half marathon long runs, why you’re running them that way, and if you should be doing something different.
This is week #2 in May’s You Don’t Know the Half of It: Half Marathon blog series. Check out last week’s breakdown of half marathon workouts here.
Don’t Know the Half of It: Half Marathon Long Run Essentials
Why a Long Run?
While the saying is, “You can half-ass a half marathon,” prioritizing the long run in your training can lead to faster times on the race clock.
A long run will…
- Make you more comfortable with the distance of the half marathon
- Build your cardiovascular system in ways shorter runs cannot
- Change your body on a cellular level into a powerhouse
- Increase your endurance for half marathon and beyond
- Increase your speed endurance for all distances by strengthening your aerobic system
The great thing about the long run for the half marathon, is that it isn’t as time consuming as the marathon’s long runs, but they should still be sacred in your eyes. Often times for frequent half-marathoners, their midweek training is already maxed out by time constraints, but improving their long run will go a long way to improving their half marathon performance.
How are you running your long runs?
Increase your long run by 1-2 mile or 15-20 minute increments. Since long runs for half marathons don’t build as high as marathon long runs, I often take the opportunity to increase long runs by 1 mile or 15 minute increments. Given the proper running base, we can get up to 15 or 16 miles, do some shorter long runs with a speed component, or both. These long run workouts boost confidence and fitness for the race when basic distance begins to feel easy.
Does my week support my long run?
Despite the wonderful benefits and values of a long run, you can’t just run 10 miles every Saturday and take the rest of the week off. You need appropriate shorter runs throughout the week to support your long run, to minimize injury risk, and keep fitness gains.
Preferably your shorter, maintenance runs will be half the distance of your long run. For example, regular runs of five miles supports a ten mile long run. Or looking at total mileage, your long run is 25-33% of your weekly mileage. Both of these guidelines are great for base running, but as you get deep into your training cycle, it may not be feasible. You may want to peak with a 16 mile long run, but be unable to increase your midweek mileage accordingly in that same span of time — this temporary imbalance can be OK with a strong running base. Just don’t make it a regular off-season occurrence.
You can also offset this imbalance between midweek miles and long run miles by developing a medium-distance run during your week. Maybe you can’t run 6 miles every midweek run, but you could on Wednesday. You might run 3 miles / 6 miles / 3 miles / 8 miles. Now you’re long run is at 40% of your weekly mileage. Add in another day of 3 miles, and you’re at 35%, further minimizing the injury risk from an “acutely long” long run.
Am I running my long run too fast?
Unless you’re purposefully running goal pace miles or another specific workout, your long run should be done at easy, conversational pace. These runs are about time on your feet and encouraging your body to improve its aerobic system, so don’t rush your long runs – you’ll lose the benefits.
If you find yourself slowing at the end of your long runs, try starting slower next time. You’re looking for a steady pace without panting, without unintended walking breaks, and with the ability to take a quick phone call or chat with a partner.

When am I ready for overdistance?
If you’ve…
- Raced at least one half marathon,
- Have a high-mileage base (ie, you’re already running 8-10 mile runs), and
- Have the time to build the distance safely with proper rest
then you’re probably ready for overdistance runs. 13 or 14 miles may be enough stimulus for your first over-distance training cycle. Later, overdistance of 15 or 16 miles could be beneficial to make the half marathon feel more comfortable and build aerobic endurance.
When am I ready for speedwork within the long run?
- When you’re ready to progress to overdistance or you already have,
- You’ve already incorporated speedwork in shorter runs during the week, and
- Your long runs feel easy.
Rather than continuing to pile on miles onto your long run to make it harder, you can sprinkle in a few faster miles to increase the difficulty of the workout.
Should I fuel my half marathon long runs?
Fueling is individual to everyone. For runs less than 16 miles, you may want to eat a small meal before your long run and run without mid-run fuel with the philosophy that your body will learn to more effectively burn its fuel stores. Or, you may want to fuel mid-run any run over 60 minutes. I at least recommend fueling for any “high quality” long run, such as race pace miles where performance is the goal vs time on your feet. Also, use one or two long runs to practice your race-day fueling to remember the logistics and test your stomach.
Learn more about fueling the long run here.
Can’t I just stick with a 8 (or other number) mile long run every week?
From a running science perspective, you introduce a stressor to trigger fitness gains. Eventually the body adapts to the stressor and fitness plateaus. By changing up the stressor – by changing the distance, pace, terrain – you improve. Keeping the same variables day after day will make you very efficient at those specific variables. Change it up to improve.
In the long run…
The long run takes up a lot of your time. Make sure you’re supporting it with reasonable midweek workouts and conscious decisions regarding fueling.
Then, make sure you’re getting what you need out of it. If not, switch things up. If you’re not sure what changes to make to your training cycle, I’d be happy to help. I do online coaching and custom plan designs.

Beirut, Lebanon

A deadly Israeli airstrike on Hezbollah’s stronghold in southern Beirut on Friday has left over a dozen people dead, including a high-ranking Hezbollah commander, sharply escalating the conflict between the two sides and raising fears of all-out war.

Senior Hezbollah commander Ibrahim Aqil, part of Hezbollah’s elite Radwan Force, was assassinated along with “about 10” other commanders, Israel Defense Forces (IDF) spokesperson Daniel Hagari said, accusing them of planning to raid and occupy communities in Galilee in northern Israel.
Hezbollah confirmed Aqil’s death on Friday, saying he was killed “following a treacherous Israeli assassination operation on 09/20/2024 in the southern suburbs of Beirut.”
According to Hagari, the targeted commanders were “underground underneath a residential building in the heart of the Dahiyeh neighborhood, using civilians as a human shield” at the time of the attack.
Lebanon’s health ministry said at least 14 people were killed and 66 others injured in the airstrike, which leveled a multistory building in a densely populated neighborhood.
Aqil had a $7 million bounty on his head from the United States for his suspected involvement in the 1983 strike on the US Embassy in Beirut, which killed 63 people, as well as the bombing of the Beirut Marine barracks, which killed 241 US personnel later that year.
A CNN team on the ground in Beirut saw a frantic effort to rescue people from underneath the rubble and rush the wounded to hospital. Witnesses said nearby buildings shook for nearly half an hour after the strike, which the IDF said it had carried out at around 4 p.m. local time.
A week of surprise attacks
Friday’s strike marked the fourth consecutive day of surprise attacks on Beirut and other sites across the country, even as Israeli forces continued deadly strikes and operations in Gaza and the occupied West Bank.
The first major attack against Hezbollah this week came Tuesday afternoon when pagers belonging to the militant groups’ members exploded near-simultaneously. The pagers had been used by Hezbollah to communicate after the group’s leader, Hassan Nasrallah, encouraged members to switch to low-tech devices to prevent more of them from being assassinated.
Almost exactly 24 hours later, Lebanon was rocked by a second wave of explosions, after Hezbollah walkie-talkies detonated in Beirut and the south of the country on Wednesday.
At least 37 people were killed, including some children, and more than 3,000 were injured in the twin attacks.
In a United Nations Security Council meeting on Friday, UN human rights chief Volker Turk on Friday warned that the detonation of communication devices could violate international human rights law.
Lebanese Foreign Minister Abdallah Bou Habib and Israeli Ambassador to the UN Danny Danon clashed at the heated meeting, with Bou Habib calling on the council to condemn Israel’s actions and Danon slamming the Lebanese envoy for not mentioning Hezbollah.
