According to LetsRun.com Shelby Houlihan will return from her four-year doping suspension on February 1 at the Razorback Invitational in Fayetteville, Ark.
Houlihan is scheduled to race in the 3000-metre event. The American record holder in the 1500m tested positive for the banned performance-enhancing substance nandrolone in December 2020.

Houlihan’s last official race was a 5000m outdoor event where she clocked a 15:02.55 performance on Dec. 4, 2020. She did, however, run in the unsanctioned Beer Mile World Classic in 2023.
Houlihan also has the Bruce Lehane Scarlet & White Invitational at Boston University on Feb. 8 on her schedule. It is likely that she wants to race smaller events to return to race effort with less pressure — it has been four years after all.
Houlihan and her coaches Jerry Schumacher and Shalane Flanagan, along with a lawyer, had hit the news hard denying the possibility of doping. Schumacher and Houlihan had said that they had not heard of the PED. The defence during an appeal was famously called Burritogate, as Houlihan, now age 31, had cited a burrito from a food truck as potentially contaminated.
Houlihan owns personal bests of 3:54.99 in the 1500m, 14:23.92 in the 5000m and 1:59.52 in the 800m.
