Career She made her debut on the world level at the 2021 World U20 Championships, where she reached the semi-final, followed by the 2021 Junior Pan American Games where she won a bronze medal in the mixed relay, finished fourth in the 100 metres and 4 × 100 metres relay, and was disqualified in the 200 metres and 4 × 400 metres relay. At her second World U20 Championships in 2022, she reached the semi-final in the 100 and 200 metres. She finished fifth in the 100 metres at the 2022 Bolivarian Games and seventh at the 2023 Central American and Caribbean Games, but here she won her first international senior medal, a bronze in the 4 × 100 metres relay. The Dominican Republic team followed up with another relay bronze at the 2023 Pan American Games, where Alonso finished fifth individually. Late in the season, she set a personal best of 11.37 seconds in Cali.
In 2024 she competed at the World Athletics Relays and at her third World U20 Championships.
Alonso's breakthrough came in 2025. She first ran two indoor meets in the US, setting a 60 metres time of 7.31 seconds – a national record – before lowering her 100 metres PB to 11.25 at the first outdoor meet in Bayaguana. Three weeks later, she ran 11.17 in Santiago de los Caballeros—returning to the US in June to run 11.15 in Winter Garden. During the European summer meet circuit, she further improved to 11.14 in Varberg and 11.13 in Schifflange. At the 2025 domestic championships, she ran 11.14 in the heat and 11.04 in the final. Two weeks later, 11.10 gave her the silver medal at the 2025 NACAC Championships, and one week after that, she won the 100 metres silver and 200 metres gold at the 2025 Junior Pan American Games. Her winning time in the 200 metres was a championship record, as was the 100 metres time of 11.08 which she achieved in the heats. She also qualified for the 2025 World Championships.
