The world of cycling mourns Jonathan Cantwell who died Tuesday night aged 36. He raced professionally from 2008-2014.

Australian Jonathan Cantwell, a professional rider for seven years, died Tuesday night at the age of 36.

According to a GoFundMe page set up as The Jonathan Cantwell Family Fund, he “lost his battle to mental illness.”

Cantwell began his career in 2008 with American Continental team Jittery Joes. The following season he raced with Fly V Australia. That 2009 season proved fruitful with two stage wins at the Herald Sun Tour on the first and last days.

After three years with that Australian outfit, he stepped up to the WorldTour with Saxo Bank-Tinkoff.

He debuted at the Tour de France that rookie season in 2012. His best result there was sixth in the stage 4 sprint behind the day’s winner Andre Greipel.

After a second season with Saxo Bank, he returned to an Australian team, Drapac Professional Cycling, for the final year of his career. In 2014, he raced predominantly in Oceania and Asia with Drapac.

According to News.com.au, Cantwell underwent successful surgery and chemotherapy to treat testicular cancer in 2017.

On Wednesday, the GoFundMe page was launched to raise money to support his grieving family, which includes his two children, Jayce and Elly.
