Race calendar · February 2027
20 ultramarathons across the US in February 2027, sorted by date. Which weekends are busiest, what the fields actually run, entry fees, and where each one starts.
February ultras put you in a genuine winter environment across most of the country. The South and Southwest offer runnable conditions, but expect mud and ice in the North and Midwest, and short daylight windows everywhere. These are not ideal circumstances, and that is largely the point for the runners who show up.
For many athletes, a February ultra functions as an early-season tune-up or a long training effort before a spring goal race, rather than a peak performance target. Setting that expectation before you register shapes everything from your pacing to your gear list.
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 February
Ultramarathons are not spread evenly across February. 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 February Ultra, from the most recent published results.
It is one of the busier months. February carries 20 Ultra races, against 37 in April, which is the fullest month of the year. There is a real choice of dates here, with less competition for entries than the peak of the season.
Layering is essential because February conditions vary more than in any other ultra season. Start with a moisture-wicking base, add insulation for cold mornings, and carry a windproof shell if there is any chance of rain or wind. Waterproof trail shoes matter if your course has mud or stream crossings. Drop bags let you adjust layers as the day warms.
Most ultra training cycles run four to six months, putting your build squarely in autumn. That means training through shorter days and colder weather before your race even arrives. If your February race is a tune-up effort rather than a goal race, a shorter build is reasonable, but you still need time on feet in winter conditions to prepare for what the course will actually feel like.
It depends on how much weather risk you are willing to accept. Races in Florida, the Carolinas, and California generally offer mild and reliable February conditions. Northern and Midwestern events can mean ice, deep mud, or course changes depending on the week. If your target race is in a cold region, build a contingency plan around conditions you cannot control.
Yes. February days are short, and any race covering fifty miles or more will almost certainly involve darkness at one end or the other. Verify whether your event requires a headlamp and for how many hours. Loop formats, which appear in several February events, make crew access and lamp handoffs simpler than point-to-point courses in low-light conditions.
The busiest weekend is February 20 and February 21, with 8 of them. Another 3 fall on a weekday, which is worth knowing if you are traveling for one.
Across the 10 of these February ultramarathons with published results from past editions, the median finisher ran 6:18:32, and the median winning time was 4:15:07. So anything under 6:18:32 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 30 runners, across the 10 of these February ultramarathons 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 8:44:28.
California has 3, Florida has 3, North Carolina has 3, Arkansas has 2, Oklahoma has 2. If you are willing to travel, those are the states where a February weekend gives you the most to choose from.
Yes, 4 races around the United States get you off the pavement: 3 are trail races, and 1 mixes road and trail.
