Running for Time vs. Distance: Experts Explain Which Is Better for Your Goals

Whether your goal is to run a marathon or simply improve your fitness, following a solid training plan will help you stay consistent as you work toward that goal. But with so many options to choose from, finding the right training plan can feel tricky.So where do you start? Consider this: Most plans fall into the very broad categories of time-based versus distance-based running. In other words, a plan prescribes runs in terms of minutes or in terms of miles. There’s no clear evidence that one is inherently superior for race-day performance, but each approach does have specific advantages and disadvantages.To help you determine whether time-based running or distance-based running is right for you, we tapped three experts to explain the pros and cons of each. They break down exactly what to consider so you can pick the type of training plan that best fits your schedule, preferences, ability level, and race goals.Distance-Based Training PlansAdvantagesDistance-based plans, or those that provide specific mileage goals for each workout, are incredibly common. That’s in part because they make a lot of sense for runners training to race a certain distance, such as a 5K, 10K, half marathon, or full marathon. Runners need to prepare their bodies for the specific mileage of their chosen race, Janet Hamilton, CSCS, an exercise physiologist and the founder and head coach of Running Strong, tells Runner’s World. And following a distance-based plan is a great way to ensure you’re getting in the right number of miles.Aside from preparing you physically for a race, distance-based plans can provide a powerful mental boost. Knowing you’ve successfully run a given distance before you toe the starting line—whether that’s logging three miles prior to attempting a 5K, or 20 miles in advance of a marathon—can give you confidence that you’ll be able to finish the race you’re gearing up for, says Jacob Phillips, a Texas-based run coach with RunDoyen.Distance-based plans can also clue you into your current performance levels. For example, if you run six miles at a hard effort, you’ll get a good grasp on your 10K abilities. “You know exactly where you stand over the prescribed distance,” explains Ken Rideout, a masters marathon world champion and nationally best-selling author of the memoir, Everything You Want Is on the Other Side of Hard.DisadvantagesThe biggest downside of a distance-based plan: If it’s not coupled with instructions on how to pace yourself or what effort level to strive for, then it’s up to you to manage those details. And in Hamilton’s experience, many runners, when left to their own devices, complete their workouts at lactate threshold pace. That’s about the same effort at which you’d race a 10K or half marathon—much faster than you want to do your daily runs.While there are certainly benefits to running at faster paces, you don’t want to miss out on all the perks of easy-pace running. Keeping your daily runs at a comfortable, conversational effort helps develop slow-twitch muscle fibers, improves running economy, and may even reduce your injury risk.Time-Based Training PlansAdvantagesMany beginner-friendly plans and run/walk programs use time as the main training parameter. One perk of this approach is that timed runs can be “a lot less intimidating” than distance workouts, says Rideout. “When you’re running a prescribed distance, you can’t help but notice, what was my pace? What were my mile splits?” he explains. But the format of a time-based run automatically reduces the prominence of those metrics, which can be helpful if you’re just easing into a running routine.Experienced runners might find similar benefits to this approach. For folks who get frazzled by having to check their mileage throughout a run, or those who get obsessive about pace, a time-based plan may be a soothing alternative. “It’s not as stressful,” Phillips explains. “I think there’s a simplicity to saying, ‘Hey, you’re going to go out and just run for half an hour,’” without having to worry about completing a certain route or number of miles.A time-centric approach can also encourage athletes to embrace easy-effort runs because it removes intrinsic pressure to run hard, says Phillips. After all, if time is the only goal, it doesn’t matter how fast you go—you’ll be successful in that day’s workout by simply moving for the prescribed duration.This can also make time-based training a good idea for busy runners. Say you only have 30 minutes today to break a sweat. With a duration-focused plan, you’ll be able to complete your planned workout, even if variables such as the terrain you’re running over or your energy levels that day impact your usual pace. No matter what happens, you’re done in 30 minutes.Opting for timed runs can also make sense for folks who are trail running in off-the-grid locations where there are no mile markers and GPS devices don’t always function well, says Hamilton. Instead of fixating on how far they’ve run—which may be challenging if not impossible given the circumstances—runners can be successful by simply going out for a certain number of minutes.A duration approach may come in handy for traveling runners, too, says Hamilton. When you’re in an unfamiliar location, there’s no need to expend effort trying to figure out how to make a five-mile loop from your hotel. Instead, you can run out-and-back for 45 minutes and call it a day.Lastly, because there’s less emphasis with time-based runs on achieving a certain pace, they can help you “get into different heart-rate zones and stay in a specific zone for a prescribed period of time,” says Rideout. This can be beneficial in improving your overall fitness, he explains.DisadvantagesTime-centric running isn’t for everyone. As we mentioned, if you’re training for a particular distance, a plan focused solely on duration may not give you the race-specific preparation—or confidence—you need to achieve your goal.Additionally, time-based plans might not be the best fit for runners who are strongly motivated by tracking their daily and weekly mileage or hitting new distance-based milestones.When comparing time versus distance running, know that “both ways can be very, very beneficial,” says Phillips. It all just boils down to finding the right plan that fits your goals and lifestyle.In general, new runners will likely find success with a time-based approach, while more experienced runners, especially those targeting a specific goal time in a race, “tend to do a little bit better with a volume-based approach,” says Phillips.Your personality and preferences for a training plan may also influence which philosophy to follow. “As a coach, I like saying ‘We did X amount of miles this week, and next week we’re going to do X amount of miles,’” says Phillips, noting that many of the runners he coaches also prefer to track their progress via distance logged week to week.On the flip side, “there are some people who just don’t want that,” says Phillips. “They don’t want the stress of comparing week to week or even day to day, so I think it just comes down to what you enjoy more.”Hamilton, for her part, tends to recommend plans that combine time and distance prescriptions—for example, run six miles in 60 minutes—because she finds this hybrid approach helps her athletes develop confidence in running certain distances while also keeping their pace in check.Rideout is of the mindset that a well-rounded training plan will include both types of runs. “I try to always keep things fresh, keep my body guessing, and try to optimize performance all the time,” he explains. Regularly introducing different types of training—via time-centric workouts and distance-focused runs—is a good way to ensure your body continues to adapt and improve.No matter what plan you choose, you can always sub one time-focused run for a distance-based workout, and vice versa, if you think it helps your mindset that day.Jenny is a Boulder, Colorado-based health and fitness journalist.
