Five things 8,853 races taught us. Every number here is measured, not guessed.
64% of US road races are on a Saturday and 25% on a Sunday. Thursday is the busiest day of the rest and it manages 7%; every other day of the week shares 4% between them.
That lands harder than it sounds. A 5-day trip that includes a Saturday finds a race 67% of the time. One that does not finds a race 26% of the time. Shifting a trip by a single day is a bigger lever than choosing a different city, and it is usually the cheaper one to pull.
If your dates are not settled yet, this is the thing to settle them on.
Across every destination we cover, 45% of 5-day trips come back with nothing. That is the most common single answer this site gives, and it is an honest one.
But of those empty trips, 45% have a race within three days of the window and 29% within a single day. The race is very often on the Saturday after you fly home, or the morning before you arrive.
So an empty result is worth one more look rather than a closed door: a late checkout, an early flight, or one more night. We show the near misses underneath an empty result for exactly this reason — within 3 days either side, marked as outside your dates.
Race calendars run about a year ahead and then stop. We list 300 days out, which is where the data thins rather than where we lost interest.
Far-ahead listings are real. What is missing that far out is not the race — it is the entry: 618 of the races in here have a confirmed date and have not opened registration yet. That is the most useful thing a traveller planning six months ahead can find, because it comes with a date to come back on rather than a shrug.
A race marked "registration opens" later in the year is a calendar entry, not a refusal — the mistake is reading it as "no". (An earlier draft of this paragraph used a real on-sale date as the example, and it was in the past within a day. Dates in prose are exactly what this page is about.)
This is the one that catches people out, and we hit it ourselves. The marquee race in a city — the one you have actually heard of — very often runs its own registration and appears on none of the large listing sites. Whole regions are the same, served by a local timing company nobody outside the state has heard of.
When we hand-audited two cities against local calendars, roughly half the road races were invisible to the feed we ingest. So we hand-check and add the ones we can verify — 32 of the races in here are hand-added for that reason, each with a source we checked and a date somebody re-confirmed.
The lesson generalises past this site: if a city obviously has a big race and a search shows nothing, look for the race's own site and the local timing company before concluding it is not happening.
Put the address you are staying at into the search and each race will say how far the start line is and when to leave. It is used for that search and never saved.
Two things worth knowing when you book, both of which have caught us out while building this:
The weekday shares, the horizon and the counts above are measured from the 8,853 races in this site's database whenever it restarts, so they are current rather than typed in once.
The trip-window figures — how often a 5-day trip is empty, and how often an empty one is a near miss — come from walking every possible trip across all 181 destinations, which is too slow to redo on every page load. Those were last measured on 1 September 2026. They have been stable across three very different versions of this database, so they are properties of US road racing rather than of our sample — but the date is there so you can weigh them yourself.
How this works has the rest: where the data comes from, and what it cannot tell you.
