Race calendar · June 2027
21 marathons across the US in June 2027, sorted by date. Which weekends are busiest, what the fields actually run, entry fees, and where each one starts.
June marathons in the United States are a study in geography. The South and interior lowlands are already deep into summer heat, making a 26.2 that much harder to race well, while the northern states, coastal routes, and higher elevations still offer mornings cool enough to run your best effort.
Mountain towns, lakeside courses, and resort settings show up regularly in June, and many events pair the marathon with shorter distances, so a travel weekend can work for a mixed-ability group.
Timing matters for training. A June 26.2 means your long runs fall in April and May, which is workable but requires staying disciplined through spring distractions. If heat has already arrived where you train, your long-run pacing will need adjustment and race-day expectations should shift accordingly.
What the field actually runs
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.
When in June
Marathons are not spread evenly across June. Here is how the calendar actually falls, weekend by weekend, which is the part worth knowing before you book a trip or plan a taper around one.
By the numbers
The largest field of any June Marathon, from the most recent published results.
It is a lean month for the Marathon. June carries 21, against 71 in April and 14 in August, the quietest. A June race is worth planning around rather than picking late, because the one that fits your training block may be the only one within reach.
Dress for the region, not just the month. In the northern states and at elevation, a light layer at the start is often welcome and can be shed within the first few miles. In the South or at low elevation, assume warmth from the gun: moisture-wicking shorts and a singlet, plus sunscreen, are the practical choice.
It can be an excellent one, provided you pick the right location. Races in mountain towns, along northern lakeshores, and on coastal routes often sit in places worth visiting for their own sake. The race weekend doubles as a trip, and many June events include shorter distances that travel companions or less-experienced runners can enter.
A standard build puts your long runs in April and May. If you are coming off a spring half marathon, a shorter bridge plan can work. The bigger planning question is where you train: runners in warm climates will accumulate heat-adapted long runs before the race, which affects both pacing strategy and realistic finish-time targets.
Start conservatively, even if the first miles feel easy. Heat compounds over the back half of a 26.2 in a way that surprises runners who held pace well through mile sixteen. Prioritize aid stations, keep an eye on how you feel rather than the clock, and treat a slower finish as a smart race rather than a failed one.
The busiest weekend is June 5 and June 6, with 9 of them, 5 of those on Saturday, June 5. Every one of them is on a Saturday or a Sunday.
Across the 12 of these June marathons with published results from past editions, the median finisher ran 4:31:55, and the median winning time was 2:43:54. So anything under 4:31:55 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
The median one finished 99 runners, across the 12 of these June marathons with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 7:05:24.
Montana has 4, Washington has 3, Colorado has 2, Idaho has 2, Maine has 2. If you are willing to travel, those are the states where a June weekend gives you the most to choose from.
Yes, 2 races around the United States get you off the pavement: 2 are trail races.
