For the next nine months, track and field athletes of all ages will be testing their fitness on both the indoor and outdoor ovals (and roads). 

While we know who the sport's biggest stars are, it is time to highlight five athletes who are due for a breakout season in 2025.

Olivia Markezich (3000m Steeplechase)

The former Notre Dame legend and NCAA champion is going to be a force to be reckoned with in the outdoor season, and here's why... 

For starters, by the time the US Championships come around, Markezich will have officially been with the On Athletics Club for well over a year, meaning she'll be considerably more dangerous than she was this last June, which is scary for anyone contesting the 3,000m steeplechase. Markezich is also a woman on a mission who wants nothing more than to avenge her sixth-place finish in June's U.S. Trials. 

At the U.S. Olympic Trials in June, Markezich went from second to sixth over the final 150m after a pair of awkward landings and an eventual fall. The recently-turned-pro still got to the finish, crossing in 9:14.87, a new PB. Markezich is more than capable of snagging one of those top spots this time around, and I think it's safe to say she's set to be a household name when it's all said and done.

Dylan Jacobs (5000/10,000m)

In a world full of talented American distance runners, it seems like Dylan Jacobs is always so close to breaking through. In June, Jacobs placed fifth in the 5000m, just five seconds out of the third and final qualifying spot. The three-time NCAA champion is just 24 years old and has proven as of late that he's someone to keep an eye on.

Despite only racing three times before the U.S. Trials this summer, Jacobs went toe-to-toe with athletes who had been racing for months, nearly punching his ticket to what would have been his first-ever Olympics.

Perhaps the biggest reason why Jacobs is due for a breakout season is his recent coaching switch. Jacobs took his talents to Boulder, CO, and joined the On Athletics Club last month, and now has a world-class coaching staff and training partners to help elevate his repertoire.

Amanda Vestri (Half Marathon)

Over the last few years, Amanda Vestri has put together an accomplished resume, but it wasn't until earlier this year that she was finally getting the well-deserved praise. In June, at the U.S. Olympic Trials, Vestri finished fifth in the 10,000m, keeping pace with many American stars. Earlier this month at the Orlando Half, Vestri made her debut over 13.1 miles, winning the whole dang thing in 1:08:12, the No. 13 time in American history. 

Opting for the roads, Vestri has her sights set on some big goals over the next year, starting with the 2025 World Road Running Championships. To book her ticket to sunny San Diego, CA, Vestri would need to finish in the top three at the Publix Atlanta Half Marathon in March. However, Vestri is testing the half-marathon waters again before then, she'll head to Houston, TX, to get another race under her belt.

Considering Vestri pulled a muscle and missed her originally planned debut in Valencia,  the fact that the 25-year-old has had the year she has is incredible. In addition to her 5000m (15:13) and 10,000m (31:10) she threw down over the summer, it won't be a surprise if the former Syracuse star becomes a regular on the international circuit. 

Duncan Hamilton (3000m Steeplechase)

During his college days at Montana State, Hamilton was pretty good (and still is). Though he never won an NCAA title, the three-time All-American finished runner-up twice, running as fast as 8:16.23. Since signing the dotted line and joining the Bowerman Track Club, Hamilton has continued to improve, finishing sixth at the U.S. Olympic Trials and now sporting a PB of 8:13.76.

Hamilton also etched his name into American history, breaking the 2000m national record, clocking 5:19.86. Just like many college stars see after a year or two in the professional system, Hamilton could be in line for a few accolades next year and is one of the many American men who could make the 3000m steeplechase team.

Sinclaire Johnson (1500m)

Considering she's won a national title within the last three years, it might be considered a stretch to call her a 'breakout' star, but I've got a feeling she's about to make some noise heading into the 2025 World Championships in Tokyo next September.

After breaking the tape in 2022, Johnson finished fourth behind a world-class trio but was, unfortunately, the first person to be left off of Team USA. Johnson's most recent campaign saw her run 3:56.75 and 1:59.95 for the 1500m and 800m, with the former being a lifetime best. The 26-year-old is undergoing a coaching change as well, leaving the Union Athletics Club to be coached by her fiancé, the 'Pace Pirate' himself, Craig Novak. 

With the recent pregnancy announcement from defending third-place finisher Elle St. Pierre, there is now one less challenger standing between Johnson and another national title.
