What Is a Shakeout Run? The Slowest Run of Your Race Week

Your race is days away and your training is done. The plan says rest, but your legs feel heavy, your head is busy and you keep checking the weather app. So you lace up for a run that is meant to feel almost too easy. Runners call it a shakeout.

Here is your complete guide to the shakeout run: what it is, the two kinds runners do, how long and how slow to go, when to skip it, and why so many big races now turn it into a group run.

What Is a Shakeout Run?

A shakeout run is a short, easy run that you do the day before a race. Coach Laura Norris describes it as one of the final steps of a pre-race taper. The point is to keep your body in its usual rhythm without adding any fatigue.

Where the Name Comes From

The name means what it says. Marathons.com translates it as the run that shakes things out, and points out that the idea is far older than the name. Runners have jogged before races to prepare body and mind for a very long time.

What It Does and What It Does Not Do

• Fitness: Norris is direct about this. The shakeout run does not improve fitness, so there is nothing to gain by pushing it.
• Loose Legs and Blood Flow: The Running Channel lists three jobs for it: loosen your muscles, increase some blood flow and help with any pre-race nerves or tension.
• Flat Legs After a Taper: A taper can leave you feeling flat. For runners who often feel that way on race day, Norris says a shakeout may help the legs feel more ready.
• Nerves: A few quiet kilometres give you time to think through the race and remind yourself that your legs still work.

The Two Kinds of Shakeout

The word gets used for two different runs, and it helps to know which one people mean.

Why a Race-Morning Shakeout Is a 2am Job at SGIM

Runners Connect coach Jeff Gaudette times the race-morning shakeout for about 2 to 2.5 hours before the start. At the BYD Singapore International Marathon, the half marathon and marathon both flag off at 4:30am. Count back and your race-morning shakeout would start between 2am and 2:30am. That is a very early alarm on top of an already early start, which is one more reason to do your shakeout earlier in race week instead.

How Long and How Easy Should It Be?

• Think in Minutes, Not Kilometres: Norris suggests 10 to 30 minutes depending on how much you train, and 15 to 20 minutes of very easy running for lower-volume runners. She plans it in time because the same distance takes a 4-hour marathoner far longer than an elite.
• Keep the Effort Very Light: Her rule of thumb is an effort that does not go above 3 out of 10, with breathing so easy that you could talk non-stop. If you train by heart rate, stay in zone 1.
• Add Strides Only If You Already Do Them: The Running Channel says a few strides at the end can put some pop in your legs. Race week is not the time to try them for the first time.
• A Relaxed 5 km Is Fine: Asked whether you can run 5 km the day before a marathon, The Running Channel says it will be fine for most runners, as long as you do not race it.

When to Skip the Shakeout

• You Always Rest Before Long Runs: Norris says race week should mimic your normal training rhythm. If you rest the day before every long run, race week is not the time to change that.
• It Adds an Extra Running Day: If a shakeout would take you from four running days a week to five, she recommends resting instead.
• You Are Short on Sleep: The Running Channel goes as far as saying that having extra sleep is arguably more important than a 20-minute run.
• You Will Be on Your Feet All Day: Travel, a busy race expo and walking around a new city all add time on your feet. Norris quotes coach Jack Daniels, whose plans make the day before a marathon a 30-minute easy run or a rest day, especially if it is a travel day.

Group Shakeouts: Why They Took Off and the One Trap

Norris notes that group shakeout runs surged in popularity after the pandemic, and The Running Channel says big city marathons now have lots of organised ones. Marathons.com adds that many races now hold group sessions the day before the event, sometimes led by an elite athlete.

What a Group Run Gives You

• Company: Running with people who are racing the same weekend turns a nervous week into a social one.
• Advice: You get to swap race-week plans with other runners and pick up ideas you had not thought of.
• Reassurance: Finding that you can keep up comfortably with a group does wonders for your confidence before race day.

The Trap: Running It Too Fast

Norris warns that too many runners join a group shakeout and end up running faster than their race pace. The result is fatigue on the one day you want to feel fresh. So run at the pace where you can still chat, even if that means letting the group go ahead. If other people's nerves rub off on you, Marathons.com suggests you may be better off running alone.

That is why the ATHLO+ Shakeout Run for SGIM 2026 keeps to chatting pace, with the social part saved for after the run.

The Shakeout to Be At in SGIM Race Week

Come for the run, stay for the people. The ATHLO+ Shakeout Run for SGIM 2026 is the race-week shakeout built around Singapore's running community: an easy run along the bay with the runners you will see on the start line, then an evening together at Harry's Esplanade.

Come with your club or come on your own. You will swap race plans with people chasing the same finish line, and you will probably leave with a few new running friends. It is a community run by ATHLO+, not an official BYD Singapore International Marathon event.

What Happens on the Night

• The Run: An easy 5 km run along the Marina Bay waterfront, past the Merlion and Marina Bay Sands, and back. The pace stays at chatting speed from start to finish, the way a shakeout should.
• Sharings: Race-week sharings from the community, so bring the questions you still have about race morning.
• New from ATHLO+: Be the first to see what ATHLO+ launches next.
• Food at Harry's: Stay on after the run. Food and drinks are your own, and ATHLO+ members still get a discount at Harry's with the code in their Locker.
• Lucky Draw: There is a lucky draw on the night, with the prizes shared closer to the day.
• Familiar Faces: TeamSportPlus will be there, and some of our partners are coming down too.

The Details

Wednesday sits three days before the half marathon on Saturday 5 December and four days before the marathon on Sunday 6 December. That gives you an easy, social run in race week and still leaves the last days before your race for rest. If a short shakeout the day before is part of your routine, keep it too.
