Ask any coach about the most important speed workout on a half or full marathon training plan<\/a>, and they\u2019ll probably tell you it\u2019s a threshold run<\/a>. These sessions help you run faster for longer, raising your lactate threshold ceiling, or the most intense effort you can sustain while still clearing lactate, which eventually slows you down. These workouts also improve your overall endurance, explains Brian Rosetti<\/a>, certified run coach and founder of V.O2.<\/p>\n

Executing threshold efforts requires running at a comfortably uncomfortable<\/a> pace, which can feel pretty difficult to hold for a long period of time. That\u2019s why Rosetti recommends cruise intervals as the smartest place to start.<\/p>\n

HOW TO FIND YOUR THRESHOLD PACE<\/a><\/p>\n

A cruise interval workout, originally introduced to the running community by legendary run coach Jack Daniels<\/a> in the 1980s, essentially requires running a series of intervals at your threshold pace with short rests in between.<\/p>\n

Rosetti considers cruise intervals the \u201cbread and butter\u201d of his coaching method, because they\u2019re a great way to rack up more threshold volume in your training thanks to the short breaks.<\/p>\n

\u201cThis type of training is really important whether you\u2019re an 800-meter runner right up to a marathon<\/a>,\u201d Rosetti says.<\/p>\n

Your race distance and weekly mileage will determine how often you do cruise intervals throughout your training plan. If you\u2019re working toward a half marathon<\/a> or a marathon, for example, you might do more threshold sessions than if you\u2019re training for a 5K<\/a>, Rosetti says. But no matter the distance you\u2019re eying, cruise intervals will get you to faster finishes. Here\u2019s how to do them.<\/p>\n

Why it works: This workout allows you to fit more threshold work in than if you were to go out for a 20-minute effort<\/a> because the rests in between allow you to recover before the next interval, Rosetti says. It also makes you more likely to sit right at your threshold pace for those intervals.<\/p>\n

These 1K repeats are particularly helpful because longer reps, like mile repeats, might be too challenging if you\u2019re just starting out, he adds. (Once you\u2019ve had a few weeks of experience with cruise intervals, you can progress to mile and then two-mile repeats.)<\/p>\n

How to do it:<\/p>\n

1-2 miles of easy running to warm up, followed by 4-5 strides<\/a>.3-4 x 1,000 meters at threshold pace (88 to 92 percent of your maximum heart rate), with 1-minute jogging or walking recovery between each1-2 miles of easy running to cool downRelated StoryHow to Master Cruise Intervals1. Go to Flat Land<\/p>\n

Cruise intervals aren\u2019t the ideal workout for hilly terrain; they\u2019re best performed on flat land, whether that\u2019s the track, a flat stretch of road, or the treadmill, Rosetti says. \u201cYou really want to focus on doing [cruise intervals] at a place where you can control the pace and the effort<\/a>,\u201d he explains.<\/p>\n

2. Follow the 10 Percent Rule<\/p>\n

A good rule of thumb to follow with cruise intervals is to make sure the amount of threshold work you do doesn\u2019t exceed about 10 percent<\/a> of your weekly mileage. For a runner at 20 miles per week, that would look like three to four 1,000-meter repeats.<\/p>\n

3. Don\u2019t Push Too Hard<\/p>\n

The key with threshold pace is learning how to stay in the \u201ccomfortably hard<\/a>\u201d state, focusing on how you feel during that effort, and being patient with yourself as you do more thresholds over time, Rosetti says. \u201cIt\u2019s important to understand what [threshold pace] feels like, so you really want to master that feeling,\u201d he says, encouraging runners to hit their threshold pace without relying on a watch<\/a>.<\/p>\n

You\u2019ll know you\u2019re at the right pace if you can say a few words out loud to a running buddy, but you definitely don\u2019t want to keep chatting. You should feel physically relaxed, as if you\u2019re tempted to slow down<\/a> or speed up a little (but don\u2019t), and you shouldn\u2019t feel any heaviness or tightness in your legs. \u201cIf you feel like the backs of your legs are getting heavy, that probably means the lactate is accumulating faster than you\u2019re clearing it, so you have to back off a little bit,\u201d Rosetti adds.<\/p>\n

Another thing to keep in mind: A \u201cgood workout\u201d isn\u2019t necessarily the one that makes you sore<\/a> or depleted, but one where you stick to your pace consistently, without overdoing it, Rosetti explains.<\/p>\n
