María Guadalupe González Romero (born 9 January 1989), better known as Lupita González, is a Mexican racewalker. She was the silver medalist in the 20km walk at the Rio 2016 Olympic Games. She was also the gold medalist at the 2015 Pan American Games and is the Mexican national record holder in the 20 kilometres race walk.
González is currently serving a competition ban due to a second anti-doping violation. The ban is due to expire in November 2026.
On her debut appearance at the 2015 Pan American Race Walking Cup she was a clear winner in the 20 km walk, crossing the line in a championship record time of 1:29:21 hours – nearly two minutes ahead of runner-up Kimberly García. González's performance led Mexico to the women's team title, alongside her compatriots Alejandra Ortega and Lizbeth Silva.[4] She was among the leading entrants at the Pan American Games two months later and came away with the gold medal, restoring Mexico's initial success in the event which had ended after Victoria Palacios's win in 2003. Hot and humid weather conditions during the race in Toronto affected González, who despite having a winning margin of over half a minute and breaking the games record collapsed after finishing the distance.[5]
María Guadalupe then won the Race Walking World Cup in Rome and was regarded as one of the favorites to win the Olympic Games,[6] and won silver, becoming the first female Mexican race walker to step on the Olympic podium.[7]
González has received two competition bans for anti-doping violations during her career. Her first ban of four years that lasted from November 2018 to November 2022 was issued after testing positive for the use of trenbolone.[9] An appeal has dismissed in 2020.[10] As a consequence of that ban, González received a second anti-doping violation band of four years to run from November 2022 to November 2026 due to tampering with the first investigation that included submitted forged documents and false testimony.[11][12] An appeal was dismissed in 2023.[13]
