⏵ Course guide · The world's largest 10K
Every July 4, up to 60,000 runners take on a fast downhill start, Cardiac Hill near mile 3, and Atlanta's brutal summer heat. I will walk you through how to get in and the course first, then give you a pacing plan for the hill and the heat, plus free tools to dial in your own numbers.
These facts come from atlantatrackclub.org and public race reporting. Confirm the current-year lottery timeline and wave assignments on atlantatrackclub.org before you race.
The route runs point-to-point from Lenox Square in Buckhead down Peachtree Road, onto 10th Street in Midtown, and finishes in Piedmont Park.
The first couple of miles run largely downhill, which feels great and tempts a fast opening pace. That is exactly the setup for what comes next: Cardiac Hill, also called Hope Hill, a roughly three-quarter mile climb gaining over 12 stories near mile 3, right at the intersection of Peachtree and Collier.
Runners who bank speed on the early downhill often pay for it here. The climb is real, sustained, and lands early enough in a 10K that it can wreck your pacing for the rest of the race if you go in overcooked. Ease your effort on the downhill start specifically to protect your legs for this hill.
With up to 60,000 spots and still oversubscribed, entry is not first-come-first-served.
Joining Atlanta Track Club gets you guaranteed entry, no lottery involved. If Peachtree is a race you want to run more than once, or if you live in the area and value certainty, membership is the direct path.
Non-members go through an annual lottery for the remaining spots. Given the scale of demand for the world's largest 10K, do not assume you will get in on a whim; apply during the announced window and have a backup plan if the lottery does not go your way.
Two variables decide your Peachtree day: how you handle Cardiac Hill, and how you handle a hot, humid July 4th morning.
Set a grade-adjusted pace target for Cardiac Hill specifically, so your effort stays honest on the climb instead of blowing up trying to hold a flat number. The time you lose on the hill is normal; the time you lose from overcooking the downhill start before it is avoidable.
This race is hot and humid without exception. Do not carry over a cool-weather 10K goal pace; reset it with the heat and dew point calculator, and treat a slower-than-usual time as the honest result of the conditions, not a fitness setback.

⏵ Train for it with Summit Line
Get a race-day plan built around YOUR fitness, Cardiac Hill, and a hot July 4th morning. Summit Line reads your real training, builds a plan for the hill and the heat, and helps you dial in race-day pacing so race day is something you execute, not guess at.
Two paths. Join Atlanta Track Club and you get guaranteed entry; otherwise you go through the annual lottery, which is oversubscribed given a field that already runs up to 60,000 spots. If you plan to run Peachtree more than once, an ATC membership pays for itself quickly just by skipping the lottery uncertainty every year.
The signature terrain feature, also called Hope Hill, a roughly three-quarter mile climb near mile 3 that gains over 12 stories of elevation, up to the intersection of Peachtree and Collier. It arrives right after a fast, largely downhill first two miles, which means many runners hit it faster and less prepared than they should be. Respect it: ease your effort in the downhill miles before it, and expect to slow noticeably on the climb itself.
Genuinely hot, every year, without exception, since it always runs on July 4. Expect highs in the 70s to 80s Fahrenheit with high humidity even at the early wave starts, and the humidity typically matters more than the raw temperature number. This is not a course to chase a flat-weather goal pace on; plan your effort around the heat, not around a cool-weather personal best.
Bank a little discipline on the fast downhill start rather than free speed, since Cardiac Hill arrives at mile 3 and punishes runners who overcooked the opening miles. Use a grade-adjusted pace target for the hill itself, and reset your overall goal pace for the heat and humidity with the heat and dew point calculator rather than assuming a cool-weather 10K time is realistic here.
Field size. The race regularly draws around 50,000 finishers out of up to 60,000 available spots, which makes it the largest 10K in the world by participation. That scale means time-seeded waves rolling through the morning rather than one mass start, so your actual start time depends on your seeded pace group.
