Participating in road races and other running events has been steadily increasing since the pandemic. Based in RunSing up data and some other sources, about 8 million people in the United States ran at least one organized road race last year.
Finding a road race to participate in, however, can be a bit of a mess. The ‘race finder’ industry is quite disaggregated. In Great Runs’ opinion, there aren’t any one or two sites that feature the combination of comprehensive listings and a clean, easy user experience.
In this article, we detail the most significant running event finder sites, with our evaluation of their strengths and weaknesses.
In our assessment, there are three main categories of sites for finding running events:
Here, we discuss some of the leading broad-based race finder sites, with an evaluation of their particular strengths and weaknesses.

RunGuides. Comprehensive listings. More focused on particular locations.
Find a Race. Newer kid on the block. Thousands of listings across multiple geographies.
Running in the USA. Largest online directory of races and clubs. Has been around for a long time!
RunSignUp. The largest registration platform for endurance events also lists races. They power some 30,000 events annually.
Ahotu. The best site for finding events internationally, with 60k events across 194 countries.
Here are a few of our favorite sites for finding specific types of events.
Marathons. Marathon Guide is a fun site focused on marathon listings, as well as race results & reviews, and curated articles related to 26.2! World’s Marathons is good for global listings. FindMyMarathon is also a decent resource.
Half-Marathons. Half Marathon Guide is a terrific resource for half-marathons. Comprehensive, well-curated lists, lots of helpful info. Also articles about half-marathons and running in general, plus a great newsletter.
Ultras. Ultra Race Calendar, powered by Ultra Running Magazine has good listings, as does the American Trail Running Association. UltraSignup is the largest registration platform for ultras and also lists races (that they power).
Trail Running. A fair bit of overlap with sites for ultras.American Trail Running Association and UltraSignup are both excellent. Trail Runner Magazine also has a race calendar.
