The end of Addy Wiley's 2023 outdoor campaign brought the best performances of her career, as the Huntington University athlete, then 19, posted personal best times of 1:57.64 and 3:59.17 at 800 and 1,500 meters, respectively. 

Those efforts were exceptional enough to land Wiley at No. 11 and No. 10 all-time on the American all-time lists, while the former mark was the fastest time of any collegian over the 2023 season across any division. 

While Wiley missed out on qualifying for the World Championships in the 1,500m, she went on to score a NACAC U23 title in Costa Rica. 

That momentum may have been enough. 

On Tuesday, the Indiana native and 2022 graduate of Huntington North High School, now 20, announced her decision to sign with track agent Paul Doyle and turn professional, inking with adidas just six months ahead of the U.S. Olympic Trials. 

Wiley will leave her collegiate career with NAIA Huntington with seven titles across her first three seasons, including a quadruple over the NAIA Indoor Nationals. 

In November, she won her last national title in cross country, clocking a time of 21:04.20 for 6K. 

Wiley gained valuable international experience at the end of 2023, securing her top 800m time in Switzerland at the Gala dei Castelli on Sept. 4 before moving on to the 1,500m in Belgium, where she clocked her 3:59.17 at the Memorial van Damme. 

Her latter performance improved upon her time of 4:03.22 from June, when she secured the World Championship standard in Nashville at the Music City Track Carnival; but it also made Wiley the fastest teenager in U.S. history, according to Lets Run.

Wiley finished her year ranked No. 8 in the world on time in the 800m and No. 19 in the 1,500m. The only Americans faster than her were Athing Mu (800m), Raevyn Rogers (800m) and Elise Cranny (1,500m). 

These moments didn't come out of left field. The Huntington North graduate finished her high school career with a national record in the 1,600m, clocking a time of 4:26.16 in 2022. 

In an Instagram post announcing her decision on Tuesday, Wiley said she will open up her indoor season on Friday.
