A shakeout run is the short, easy jog most runners do a day or two before a marathon, and Chicago has some of the best options anywhere for getting one in, from a legendary lakefront trail to a full weekend calendar of organized group runs.

What a Shakeout Run Is For (and Isn't)

The point of a shakeout run is to keep your legs loose and your circulation moving after days of travel and taper-induced restlessness, not to add fitness at the last minute. Keep it short and genuinely easy, closer to a jog than a run, with a few relaxed strides thrown in if you want to remind your legs what faster feels like. The temptation on a shakeout run is almost always to run longer than planned because the weather is nice or the company is good. Resist it. Nothing you do the day before a marathon makes you fitter, but plenty of things can make you more tired.

Where to Run One in Chicago

The Chicago Lakefront Trail answers this question almost by itself. It runs for miles along Lake Michigan, flat and mostly separated from car traffic, and it starts within a few minutes of most of the hotels runners stay in for race weekend. Twenty to thirty easy minutes out and back is plenty. If you would rather stay closer to downtown, a loop around Grant Park and the Museum Campus covers similarly flat, scenic ground without needing to travel far from the expo or your hotel.

Organized Shakeout Runs Around Race Weekend

Race weekend in Chicago typically includes a full calendar of organized shakeout runs hosted by running stores, shoe brands, and local run crews, usually easy group jogs of a few miles along the lakefront, often followed by coffee, food, or a small giveaway. Fleet Feet's Chicago locations are consistently at the center of this scene, and the specific lineup of brand-hosted runs changes from year to year, so check race-week event listings closer to your trip rather than assuming a specific run will repeat exactly as it did in past years. These are a genuinely good way to meet other runners and soak up race-weekend energy without overdoing it physically.

How to Structure It

  • Keep total time under thirty minutes for most runners, closer to fifteen if you are naturally prone to overdoing taper runs
  • Run at a pace that feels almost too easy, this is not the day to test how your legs feel at goal pace
  • Add four to six relaxed strides at the end if you want a bit of leg turnover, nothing hard or sustained
  • Do it the day before the race rather than two days before, so your legs stay loose without adding meaningful fatigue

What to Do With the Rest of the Day

A shakeout run works best as one small piece of an otherwise restful day. Spend the bulk of race-eve off your feet: sightsee a little if you want to, but save the serious walking for after the race, not before it. Hydrate, eat a meal you know agrees with you, and treat the shakeout run as a mental reset as much as a physical one, a chance to remind yourself that the fitness is already built and there is nothing left to prove before the start line.
