Pittsburgh’s biggest running weekend in history is about to land. P3R, the not-for-profit that organises the Dick’s Sporting Goods Pittsburgh Marathon, confirmed on Tuesday that the marathon, half-marathon, marathon relay and supporting events will collectively bring more than 50,000 runners and walkers across the start lines on 2–3 May. The full marathon itself sold out earlier in April for the first time in the event’s history, with organisers running a waitlist that they expect will not fully clear before the entry transfer window closes on Thursday evening.

The marathon takes its 26.2-mile loop through 14 of the city’s neighbourhoods on Sunday morning, starting at 7am from Liberty Avenue downtown. With the half-marathon, marathon relay and 5K all selling at or near capacity, the weekend takes an unfamiliar place near the top of the U.S. spring-marathon participation table, behind only the Boston Marathon among events run on the first weekend of May. The earlier mentioned 50,000-figure includes Saturday’s UPMC Sports Medicine Pittsburgh 5K, the Pittsburgh Champions Mile, the Chick-fil-A Kids Marathon, the Pittsburgh Pet Walk and the Sheetz Toddler Trot.

Conditions look near-ideal for a fast race in a course better known for its hills than its splits. Forecasts published by the National Weather Service’s Pittsburgh office on Tuesday call for a Sunday morning low of 53°F and a high of 66°F (12–19°C), with no rain on the radar and a light southeasterly wind. The marathon’s elite field is selected by invitation rather than time, and P3R has confirmed a deeper-than-usual professional and masters-level entry list, with appearance fees up roughly 12% on 2025 to chase the city’s long-standing $200,000 American time-incentive scheme.

Race week brings a familiar set of road closures across the city, with the bridges over the Allegheny and Monongahela closing in rolling waves from 5am on Sunday and the West End Circle restricted from Saturday afternoon. Mayor Ed Gainey announced a $1.4 million package of public-safety, sanitation and crowd-management spending in February tied to the marathon, and 1,400 volunteers have signed up to staff the 26 aid stations along the course—a record total that organisers say reflects a wider community lift that started during the pandemic and never fully ebbed.

For Pittsburgh itself, the marathon’s scale has implications well beyond Sunday’s finish line on the Boulevard of the Allies. P3R commissioned a third-party economic impact study from VisitPittsburgh in March that pegged this year’s weekend at $25.7 million in direct visitor spending, helped by record demand for race-weekend hotel inventory through downtown and the South Side. With the full marathon now selling out a year ahead of schedule, P3R chief executive Kris Rust said registration for the 2027 edition would open on the Tuesday after the race—a week earlier than usual.
