Sam Grewe

Grewe first leapt in to the spotlight in 2015 when he won the high jump T42 world title at just 17-years-old.

The young American had only been taking part in the high jump for a year – he didn’t even have a coach.

But if he lacked experience, he certainly didn’t show it. Grewe added a phenomenal 20cm on to his personal best, clearing 1.81m to take gold.

The following year he made his Paralympic debut at Rio 2016, finishing second behind India’s Mariyappan Thangavelu.

But in 2017 he was back at the top again, clearing a new personal best 1.93m at a high school meeting in May before going on to successfully defend his world title in London, Great Britain.

If his form continues, Grewe looks set to beat Arnold Boldt’s world record of 1.96m set back in 1980.

Grewe was diagnosed with bone cancer in his right leg in 2011; the following year his leg was amputated above the knee.
