What 9,040 races say about US road racing

The busiest race day in America is a Thursday

The single busiest date in the calendar is 26 November 2026, with 519 races. The busiest Saturday of the year has 375.

Thanksgiving morning is not a big race day — it is the race day, and it is the only one of its kind. 87% of all Thursday racing in the entire calendar happens on that one morning; every other Thursday of the year shares 78 races between them.

It is the clearest thing in the data, and it is invisible in any weekly average.

What a race actually costs

Entry prices are published per race and almost never collected. These are the currently-open entry fees on every qualifying event we hold, in whole dollars.

A 5K clusters tightly — the middle half of them sit between $30 and $40. Longer races spread out far more: the dearest tenth of marathons cost 6.7x the median 5K. 168 races are genuinely free, with no paid entry on any distance.

Two days a week, and one of them barely counts

Road racing is not a weekend sport so much as a Saturday sport.

The practical consequence, if you are fitting a race into a trip: the day of the week you are in town matters more than which town it is. A trip spanning a Saturday finds a race far more often than a longer trip that does not.

The 5K is most of the sport

Counted by entries offered rather than by races, since one race often sells several.

Why you cannot read seasonality off a race calendar

This is the number everyone gets wrong, including us before we measured it.

It looks like American racing collapses in the spring. It does not. Organisers post races two to four months ahead, so the far end of any race calendar is thin because nobody has announced yet — not because nobody is running.

We measured the difference by comparing windows exactly 365 days apart, which holds the season constant and leaves only the posting lag: eight months out, a sample of destinations returned 85 real races; twelve months out it returned zero. That is a listing horizon, not a quiet season, and it is why this site refuses to answer for dates more than 300 days away.

Any chart of "races per month" drawn from a calendar — ours or anyone's — is measuring publishing behaviour at its right-hand edge. The last few months above are marked for exactly that reason.

Method, and what these numbers are not

Every figure is computed from the listings this site holds, when you load the page. Nothing here is typed in by hand.

• The corpus is what we gather around 2,519 towns from public listings, filtered to running races between 3 and 26.3 miles. Triathlons, virtual races, walks and kids' events are excluded before any of this is counted.
• It is not a census of American racing. Races that run their own registration, and whole regions served by one local timing company, are missing — we say so in more detail on about. The weekday and distance shares have been stable across three very different corpus sizes, so we think they describe the sport; the absolute counts describe our corpus.
• Prices are the entry fee open right now. Many races charge more closer to the day, so these skew slightly cheap.
• Only dated future races count. A race we could not place on a day is excluded rather than guessed at.
