You're standing at the starting line, and instead of the usual city smells of exhaust and hot asphalt, you catch a whiff of hay and maybe—if the wind hits just right—an Andean bear. It's 7:00 AM. Chicago is barely awake, but the Lincoln Park Zoo Run 2025 is already vibrating with that weird, specific energy only runners and zoo enthusiasts can generate.
Most people think of this as just another 5K or 10K. They're wrong.
Honestly, it’s one of the few times you can sprint past a lion’s enclosure without it being a life-threatening emergency. This year, the stakes are a bit different, the course has its usual quirks, and if you haven't trained for the "Nature Boardwalk" incline, your calves are going to hate you by mile two.
The Logistics of Running Wild
Registration usually opens months in advance, and let's be real, it sells out. Fast. If you're looking at the Lincoln Park Zoo Run 2025 calendar, you're likely aiming for that first Sunday in June—June 1st, to be precise. That’s the tentative date the city circles every year.
You’ve got choices. The 10K is for the folks who actually want to feel the burn. The 5K is for the rest of us who just want to justify a massive brunch at a Lincoln Park cafe afterward. Then there's the "Safari Stride" for the kids, which is basically adorable chaos.

Packet pickup isn't just a chore here. It's usually held at the zoo itself or a local running shop like Fleet Feet. Don't wait until the morning of the race to get your bib. You’ll be stressed. You’ll be late. You’ll miss the start because you were looking for a safety pin near the flamingo pond.
Why This Course Is Actually Tricky
Don't let the flat Midwest geography fool you.
The path winds through the zoo’s west side, loops around the South Pond, and stretches out toward the lakefront. It’s narrow in spots. If you're a serious PR hunter, you need to get to the front of your corral. Otherwise, you’re going to be weaving around strollers and people taking selfies with the giraffes.
The transition from the paved zoo paths to the crushed gravel around the Nature Boardwalk can mess with your rhythm. It's soft. It sucks the energy out of your stride.

The Impact Nobody Mentions
Your registration fee isn't just buying you a tech shirt and a finisher's medal that will eventually end up in a junk drawer. Lincoln Park Zoo is one of the few free zoos left in North America. It’s privately funded. Basically, your sweat pays for the specialized diet of a black rhino or the conservation efforts for the Eastern massasauga rattlesnake.
The zoo’s Vice President of Clinical Medicine, Dr. Kathryn Gamble, and her team rely on these fundraising pillars to maintain the highest level of animal care. When you're huffing and puffing past the Pritzker Family Children’s Zoo, remember that. It makes the lactic acid hurt a little less.
What to Wear (And What Not to Wear)
Chicago in early June is a gamble. One year it’s 55 degrees and misty—perfect running weather. The next? It’s a 90-degree swamp.
- Chafing is real. Use the balm. Everywhere.
- Sunscreen. Even if it looks cloudy, that Lake Michigan reflection will fry you.
- Costumes. You'll see them. People in full gorilla suits. It’s impressive, but they are definitely suffering more than you. If you want to go themed, maybe stick to some leopard print socks or a tiger-stripe headband.
The Post-Race Scene
The "Post-Race Festival" is held on the main mall. There’s usually fruit, some bars that taste like sawdust but provide calories, and—most importantly—beer for the over-21 crowd.

Take a minute to actually walk the zoo after you finish. You’ve already paid for the "access" with your entry, though the zoo is free anyway, the atmosphere post-race is unique. The animals are often most active in these early morning hours right as the crowds start to thin out and the sun hits the enclosures.
Real Talk: The Parking Nightmare
If you try to park in the zoo’s main lot on Cannon Drive, you’re going to have a bad time. It’s expensive, and it fills up by 6:30 AM.
Take the CTA. The 151 or 156 buses drop you right there. Or, if you’re local, just jog there as your warm-up. If you absolutely must drive, look for street parking west of Clark Street, but read the signs. Chicago meter maids are more efficient than Olympic sprinters.
Actionable Steps for Your Race Day
- Register by March: This is when the early bird pricing usually disappears. Save the twenty bucks for a post-race pizza.
- Train on Mixed Terrain: Find a park with both asphalt and gravel. Your ankles need to know the difference before race day.
- Hydrate Two Days Prior: Drinking a gallon of water the morning of the race just means you’ll be standing in the Porta-Potty line when the starting gun goes off.
- Check the Corral Map: The zoo layout is a labyrinth. Know exactly where your start gate is located relative to the Fullerton entrance or the West Gate.
- Download the App: The Lincoln Park Zoo has a specific app for animal tracking and maps; it’s surprisingly helpful for finding the nearest restroom that isn't a plastic box.
This isn't just a race; it's a massive community effort to keep a Chicago icon running. Show up, don't trip on the boardwalk, and enjoy the rare privilege of outrunning a tortoise.
