Is March a good month for an Ultra?
March sits in the middle of the year for the Ultra, carrying 18 against 37 in April and 7 in July. Enough to choose from, and easier to get into than the races at the peak of the season.

Ultramarathons in March 2027
18 ultramarathons across the US in March 2027, sorted by date. Which weekends are busiest, what the fields actually run, entry fees, and where each one starts.
March ultras in the United States mean early spring in name only. Conditions vary dramatically depending on where you line up: desert courses in the Southwest can still deliver cold pre-dawn starts and exposed wind, Southern courses may already feel warm and humid, and Eastern and Midwestern trails often carry mud, snowmelt, and unpredictable footing that can matter as much as fitness.
Because the country has not settled into a single season yet, March rewards runners who prepare for range rather than a fixed forecast. Layering strategy, drop-bag planning, and footing adjustments mid-race all matter more than in the stable middle of summer. This is also a common spring-opener month, so many entrants are testing a winter build rather than peaking.
The calendar is modest, with events spread across a handful of states from Florida to Utah to California. That spread means travel is usually part of the decision, and many of these events draw runners who have planned well ahead. If a specific race or region appeals, securing a spot early is the norm rather than the exception.

Common Questions About Running a March Ultra
What should I wear for a March ultra?
Start with a light base layer you can shed, and carry a wind shell regardless of the forecast. Morning temperatures at elevation or in the desert can be cold enough for gloves and a hat even when midday turns warm. In the South and Florida, humidity is the variable to plan around, so moisture-wicking fabrics and blister prevention matter more than insulation.
How far ahead should I start training to be ready for a March ultra?
A March race puts your peak training block squarely in winter, which means long runs in cold, dark conditions and trails that may be wet or icy. Plan your build so your highest mileage weeks land in January and February, leaving room to taper before race day. Starting a structured build in late October or November gives most runners enough runway.
Is it worth traveling to a March ultra, or should I race close to home?
If you are based somewhere with difficult winter conditions, traveling to a Southern or desert race can mean better footing and a more predictable day. Florida and the Southwest offer runnable terrain when the East and Midwest are still dealing with mud and unpredictable weather. The tradeoff is heat and humidity in Florida, so weigh that against what you have been training through.
How do March ultras fit into a longer racing year?
A March finish sets up a natural recovery window before the main spring and summer ultra season. Runners who treat March as a goal race can use April and May to rebuild and target a second event in late spring or early summer. Alternatively, a March race works well as a long training effort if your primary goal is later in the year.
When in March are most ultramarathons held?
The busiest weekend is March 6 and March 7, with 9 of them. Every one of them is on a Saturday or a Sunday.
What is a good Ultra time?
Across the 12 of these March ultramarathons with published results from past editions, the median finisher ran 7:36:39, and the median winning time was 4:41:55. So anything under 7:36:39 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.
How big is a typical March Ultra field?
The median one finished 45 runners, across the 12 of these March 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 10:04:01.
Which states have the most March ultramarathons?
California has 2, Florida has 2, North Carolina has 2, Tennessee has 2, Texas has 2. If you are willing to travel, those are the states where a March weekend gives you the most to choose from.
Are there trail ultramarathons in March?
Yes, 7 races around the United States get you off the pavement: 6 are trail races, and 1 mixes road and trail.
