In 2015 Rowlings was selected to again represent Great Britain, this time at the IPC World Championships in Doha. Although he failed to take any medals, he came fourth in both the 400 metres and 800 metres races. 2015 also saw Rowlings set four British records in the same meet, when he broke the 100m, 200, 400, and 800m records at the IPC Grand Prix in Nottwil, Switzerland. The following year, in the build-up to the Summer Paralympics in Rio, Rowlings attended the 2016 European Championships in Grosseto. He medaled in all three events, improving on all his times from Swansea two years ago. He won the bronze medal in the 100m, 400m and 800m T34. In July Rowlings was named as part of the great Britain team that would be travelling to Rio to compete in the Summer Paralympics.
